Internet Monthly Report March 1992
IAB MESSAGE
NEW IRTF CHAIRPERSON
The IAB has selected Jon Postel to chair the Internet Research Task
Force, replacing Dave Clark who was forced to resign due to time
conflicts.
Jon has been active member of the Internet research community since
its beginnings in 1974, and before that played a major role in
defining the ARPANET protocols, starting in 1969. As "Protocol
Czar", he defined the final specifications of protocols such as
TCP, IP, and SMTP. As RFC Editor, he has maintained the uniformly
high editorial and technical quality of the RFC series.
IAB MEETINGS
The IAB met for 1.5 days on March 16-17, 1992 at the San Diego IETF
Meeting. Minutes of this meeting will be published when they
become available.
The minutes of the IAB meetings of November 1991 and January 1992
are now available for anonymous FTP from host venera.isi.edu with
pathnames:
pub/IABmins.nov91.txt
pub/IABmins.jan92.txt
STANDARDS ADVANCES
The following list shows the protocol standards actions approved
by the IAB since February 1, 1991.
NetFAX -- A File Format for the Exchange of Images
Proposed Standard: 17 March 1992
RFC 1314 - "A File Format for the Exchange of Images
in the Internet"
Frame Relay MIB
Proposed Standard: 17 March 1992
RFC-1315 - "Management Information Base for
Frame Relay DTEs"
TCP Extensions for High Performance
Proposed Standard: 17 March 1992
RFC in preparation.
Cooper [Page 3]
Internet Monthly Report March 1992
Character MIBs
Proposed Standard: 17 March 1992
RFCs in preparation.
IP over SMDS
Proposed Standard: 4 February 1991
Draft Standard: 17 March 1992
RFC-1209 - "Transmission of IP Datagrams over the
SMDS Service"
IP TOS -- IP Type of Service
Proposed Standard: 27 February 1992
RFC in preparation.
SMDS Interface MIB
Proposed Standard: 24 February 1992
RFC in preparation.
IP Forwarding Table MIB
Proposed Standard: 24 February 1992
RFC in preparation.
Note: The IESG recommended that the Internet Draft "IP
Forwarding Table MIB" <draft-ietf-rreq-forwarding-04>
be published as a Proposed Standard. This document
depends on the Internet Draft "Type of Service in the
Internet Protocol Suite" <draft-almquist-tos-02> and
should be published after that document. This is the
product of the Router Requirements Working Group of
the IETF.
During IESG and IAB consideration of the -04 version
of this specification, the working group developed a
-05 version and published it as an Internet Draft.
Since the differences are very minor, and indeed
probably have no effect on the resulting service, the
IAB has adopted the -05 version and will publish it as
a Proposed Standard.
We want to encourage (!) working groups to always submit
finished specifications, and discourage frequent
post-submission changes. However, forcing a recycling of
this particular specification, and thereby adding a month
of delay, seemed entirely unnecessary.
Cooper [Page 4]
Internet Monthly Report March 1992
MIB-I -- Management
Information Base
Standard: 26 April 1990
Historic: March 1992
In August 1991, MIB-II (RFC-1213) became a Standard for the
Internet. MIB-II was intended to replace the earlier MIB-I,
and in fact MIB-II is a fully backwards-compatible extension
to MIB-I. Therefore, MIB-I has been demoted from Standard to
Historic (an honorable end for a notable IETF effort). This
new state for MIB-I is reflected in the current "IAB Official
Protocols Standards" RFC-1280 (March 1992).
STANDARDS ACTIONS PENDING ON APRIL 1, 1992
'BGP NEXT-HOP-SNPA Attribute' to Proposed Standard.
Held up for discussion with IESG. Concern was general
architectural issues raised by this specification.
'Mapping between X.400(1988) / ISO 10021 and RFC 822'
to Proposed Standard.
Approved by the IAB, pending resolution of an organizational
issue with the IESG.
'X.400 1988 to 1984 downgrading' to Proposed Standard.
The IAB believes it is entirely appropriate to progress an
Internet standard for the 1988->1984 X.400 fallback, even
though the spec is the subject of CCITT and ISO standards.
Approved by the IAB, pending resolution of an organizational
issue with the IESG.
'SNMP Security' to Proposed Standard
Held up for discussion with IESG area and WG chair. Revision
in preparation.
'Point to Point Protocol (PPP)' to Proposed Standard.
Ballot in progress.

RESOURCE DISCOVERY AND DIRECTORY SERVICE
----------------------------------------
The Internet Research Task Force on Resource Discovery and
Directory Service met in March, and discussed the problem of how
to allow resource discovery systems to scale by several orders
of magnitude. We began by exploring the current paradigms for
resource discovery, and by proposing some experiments for the
group. We are now considering a problem we call "Perspective
Discovery". The idea is that as an increasing number of
information services, indices, etc., are interconnected on the
Internet, we see a burgeoning "Web" of information. For
example, there are now gateways/access methods between Archie,
X.500, WAIS, Prospero, WWW, etc. For this web to be useful,
there need to be ways to locate useful entry points. Such entry
points are being built and exported by individuals or groups,
with an impetus for their entry points to become popular. We
are currently exploring an architecture that would allow entry
points to be advertised, interrelated, and discovered. This
approach is different from the directory-of-directories
approach, since it does not imply a cascading hierarchy (where
eventually there are directories of directories of directories,
etc.), and scalability is achieved through specialization rather
than global nesting.

INTERNET ENGINEERING REPORTS
----------------------------
1. The IETF met in San Diego March 16-20, 1992 and was hosted by
San Diego Supercomputer Center. Many thanks are due to Paul Love
and all the folks at SDSC for the amazing amount of work that
went into hosting this meeting, and to the staff at the Hyatt
Islandia. The facilities were outstanding and the location was
beautiful. Megan Davies again demonstrated her superior
abilities at scheduling and coordination as we managed to avoid
rain until Friday afternoon. 64 working groups, BOFs, and
directorates met during the week.
In addition to being a productive meeting, the San Diego IETF
meeting enjoyed a number of "firsts." This was the first meeting
where attendence broke the 400 person mark. It was also the
first to break the 500 attendee mark! There were over 525
attendess in San Diego.
Another first for the IETF meeting was the audio broadcast of
the technical presentations and plenary meetings, thanks to the
efforts of Steve Casner, Steve Deering, and a host of others.
There were a number of receiving sites in the United States,
the UK, Sweden, and Australia
2. The next IETF meeting, co-hosted by MIT and NEARNet, will be
held in Cambridge during the month of July, 1992. Details will
be provided in future Internet Monthly reports and announced to
the IETF mailing list.
3. The IESG received a revised version of the "MIME (Multipurpose
Internet Mail Extensions)" Internet draft
<draft-ietf-822ext-messagebodies-05.txt> This document reflects
both specific editorial changes requested by the IESG and minor
corrections. A second last call was sent.
4. The IESG made the following recommendations to the IAB during
the month of March, 1992:
a. SNMP Administrative Model <draft-ietf-snmpsec-admin-02>
be published as a Proposed Standard.
b. SNMP Security Protocols <draft-ietf-snmpsec-protocols-02>
be published as a Proposed Standard.
c. Definitions of Managed Objects for Administration of
SNMP Parties <draft-ietf-snmpsec-mib-02> be published as
a Proposed Standard.

INTERNET PROJECTS
-----------------
BARRNET
-------
Three new 56kbps sites, one T1 site, and one dial-in site were
connected in March. Implementation of routing to the CIX remains
delayed pending resolution of routing issues. Circuits were
ordered to complete a T1 loop between BARRNet's hub sites at
Stanford, Davis, Sacramento, and Menlo Park, providing a fully
redundant T1 path to the NSS for sites in the Sacramento Davis
area. A similar loop is planned for the Stanford/NASA Ames/Santa
Clara/Cupertino hub sites.
Paul Baer <baer@jessica.stanford.edu>
BOLT BERANEK AND NEWMAN INC.
----------------------------
Inter-Domain Policy Routing
In March 1992, the IDPR working group submitted IDPR to the IESG
for Proposed Standard status consideration. BBN continued to
assemble a group of participants for IDPR experiments within the
Internet and met with some of the potential participants.
In the previous month, BBN fulfilled its commitment to producing
the IDPR configuration database software. With the subsequent
maternity leave of BBN's IDPR software engineer, BBN is not
currently working on the gated version of IDPR. SAIC is leading
the IDPR gated development effort. Please refer to their
submission for a discussion of the status of that software.
ST Conferencing
During March, a total of 30 video conferences and demonstrations
were conducted. Six of the conferences involved three sites, one
(by special arrangement) involved four sites, and the remaining
twenty-three included only two sites. A large number of these
conferences were associated with the Reforger FV demonstration.
The DART project also used conferencing services. There were no
SIMNET exercises in March.
During March, BBN developed and began field testing for new T/20
software to ensure that the gateways do not drop priority packets
such as ST conferencing packets when the traffic load exceeds the
fatpipe capacity. This had caused a problem with UK/US video
Cooper [Page 11]
Internet Monthly Report March 1992
conferencing. Preliminary field testing has been successful, and
will continue in April.
Ft. Leavenworth joined the TWB as a new conferencing site, and
participated in the FV conferences and simulation (non-SIMNET)
exercises. Frankfurt also joined the TWB temporarily for the FV
demo, and will return as a regular conferencing site when a
permanent data connection to Frankfurt becomes available.
Jil Westcott (westcott@bbn.com)
CERFNET
-------
During April CERFnet will be moving their headquarters from the San
Diego Supercomputer Center (SDSC) to General Atomics headquarters
just down the street. In the new location CERFnet will have new
Network Operations Center (NOC) facilities and extensive additional
space for its expanding staff. Our 800 number (800-876-CERF) will
remain the same, but our direct line will change to (619) 455-3000.
Our mailing address will remain the same - CERFnet, P.O. Box 85608,
San Diego, CA. 92186-9784.
CERFnet staff attended the Net '92 conference in Washington D.C.
and introduced the prototype of a board game - "The LAN That Time
Forgot." The game provides a fun way to learn about the Internet as
you travel through different e-mail, FTP, and Telnet paths. People
were enthusiastic about the game and had good suggestions for
additional improvements. The game will be completed and released by
early Fall.

CICNET
-------
CICNet activities for February and March, 1992
On February 4, the winter meeting of the CICNet Network Information
Resources Committee was held in Chicago. The meeting was attended
by over 30 participants from almost all CICNet sites. Featured
presentation included a discussion of a full text database service
by John Price-Wilkin of the University of Michigan, activities at
the Coalition for Networked Information by Craig Summerhill of CNI,
and a presentation on the Gopher information service by Mark
McCahill of the University of Minnesota.
Cooper [Page 12]
Internet Monthly Report March 1992
Also during February, CICNet President Mike Staman represented
CICNet at meetings of FARNET and the Midamerica Coalition for High
Performance Computing. Mike was also elected to the Board of
Directors of FARNET.
At the end of the month CICNet staff participated in series of
meetings in Illinois which were designed to inform education,
business and industry of the development of net ILLINOIS. The
meetings were attended by over 200 individuals.
During February, 9.6 billion packets were switched by all routers
on the network and 3.76 billion packets were accepted into the
network. This represents a 20% increase over January in the number
of packets accepted into the network.
On March 5th and 6th, the CICNet Technical Board met at the
Ameritech headquarters in Rolling Meadows, IL. Topics for this
meeting included planning for an SMDS trial in the Chicago area and
a discussion of dialup services. New members joining CICNet in
February and March include Share, Inc, the Illinois Institute of
Technology - Kent College of Law, and the Motorola Corp.
During March a project to upgrade all of CICNet's Cisco backbone
routers to CSC/3 processors was completed. CICNet has recently
established an active WAIS server which provides an easy way to
search a list of Bitnet node sites, UUCP sites, Internet mailing
lists, and email addresses for individuals who participate in
USEnet news groups.

CONCERT
-------
CONCERT added six new Universities/Colleges this month to its list
of connected sites. The new schools include Catawba College, Chowan
College, Elon College, Meredith College, Queens College, and Shaw
University.
CONCERT staff members participated in the National Net 92
conference held in Washington, DC. The CONCERT staff demonstrated
their current Packet Video Videoconferencing facilities. National
Net 92 visitors were able to view in a workstation X Window the
regularly scheduled programming on the MCNC's CONCERT Video
Network's general purpose channels. Viewers were also able to
participate in interactive collaborative sessions with people in
MCNC`s Visualization Center located in Research Triangle Park,
North Carolina. The production ANS T3 network was used for the
communications from Washington to Research Triangle Park.
CONCERT staff also particpated in the IETF workshop held in San
Diego. At the IETF, work on the CONCERT trouble ticket system was
presented to the UCP working group. The trouble ticket system is
based on freely available software tools, including the postgres
database package available from Berkeley. Testing of the system is
in progress, and it is planned for the system to be made available
to interested sites "real soon now" (hopefully by the end of April,
or early May).

FARNET (FEDERATION OF AMERICAN RESEARCH NETWORKS)
-------------------------------------------------
FARNET activities for February and March, 1992
FARNET sponsored a workshop on improving end-to-end reliability and
operations capability in the Internet, on February 10-12, with
support from the National Science Foundation. Attendees included
technical and management staff from FARNET member organizations and
representatives from HPCC agencies, the IETF, two RBOCs, and the
library community. Preliminary results were released before the
March IETF meeting. A final report will be available in about
three weeks. More information about the workshop is available on
host farnet.org via anonymous ftp. Look in the
/farnet/farnet_docs/orlando-ws directory. Note that the results
are not fully processed yet; the final report will contain our
complete recommendations.
FARNET President Eric Hood testified before the Subcommittee on
Science of the House Committee on Science, Space and Technology on
March 12. Hood praised the performance of the National Science
Foundation in managing the NSFNET program and called for the
extension of network services to new communities, cooperation among
Federal agencies in the NREN program, and relaxation of the NSFNET
"Appropriate Use Policy" to permit greater commercial use of the
network. The full text of his testimony and that of the other
witnesses is available on host farnet.org, directory /farnet/nren.
FARNET is working on a number of project ideas in K12 networking,
including one with the national consortium of magnet high schools
of science, math and technology. FARNET and magnet school
representatives met in Maryland on March 22 to discuss how a joint
project might be implemented and have agreed to work together on a
preliminary proposal.
FARNET and Merit sponsored a series of demonstrations at National
Net92 (March 25-27) to showcase how people are using the Internet
today to support education and research, in settings from
elementary school to graduate school. Archie, WAIS, Gopher, the
Merit Cruise of the Internet, and several K12 applications were
demonstrated. Other FARNET members exhibiting at the meeting
included CONCERT/MCNC and Cornell University.
The next FARNET meeting will be held in Research Triangle, North
Carolina, May 13-15. The topic is "Business and Strategic Planning
for Your Organization." Guest registrations are available. For
more information, contact Laura Breeden at FARNET.

MULTIMEDIA CONFERENCING
The March IETF meeting in San Diego was an exciting one for those
interested in teleconferencing. The general sessions plus sessions
of the Audio/Video Transport working group and the Teleconferencing
Architecture BOF were "audiocast" using packet audio over the
Internet to listeners at 20 sites on three continents spanning 16
timezones. In the AVT WG, Steve Casner set forth a rough strawman
for a real-time transport protocol and led a discussion of how it
should be modified. This protocol should replace the out-dated
Network Voice Protocol we are using temporarily in the packet audio
programs. The goal is to have the new protocol ready for use in
programs on a wide variety of platforms in time for a second
audiocast from the Boston IETF.
In the Telearch BOF, Eve Schooler gave a presentation on the
Connection Control Protocol. Flexible management of multimedia
connections will be the next big step required for packet
teleconferencing to work on more than an experimental basis.

C. JvNCnet K-12 Dial-up Connectivity Program
JvNCnet is currently providing network access to the New
Jersey Department of Education and several public school
districts in the state. The Internet link enables students and
teachers to use a variety of databases and interactive
applications to complement classroom experiences and
significantly expands the channel of communication for both.
Teachers exchange novel ideas and instructional strategies as
well as obtain expertise from diverse educational
professionals and members of the academic and research
communities. Children learn about peers who live in different
cities or even countries, practice using a foreign language,
participate in mentoring with undergraduate friends, and
access the World Fact Book, NASA Space Link, or remote library
card catalogs (to acquire a book through inter-library loan),
all via the Internet. Montgomery, Bergenfield, Lawrence
Township, Ridgewood, West Windsor-Plainsboro, Roselle Borough,
and South Brunswick are exploring the network and are finding
out about its wonderful stored treasures and how children are
inspired and engaged using them. The potential? Students
will continue communicating, searching, reading, and learning
more about something they are interested in.

NSFNET/ANSNET BACKBONE ENGINEERING
----------------------------------
T3 Network Status
=================
The T3 network remains very reliable and during the month of March
it carried 5.8 billion packets. During March we cut traffic over
to the T3 system from NASA (FIX-E), JVNCNet, and MidNet. A new T3
ENSS was installed at FIX-W. Installation of the T1/T3
interconnect gateway at Princeton was completed, to act as a backup
for the Ann Arbor interconnect. The T3 link between Chicago and
Palo Alto was re-routed to reduce the overall circuit distance and
network latency during March. A temporary T3 ENSS was installed at
the National Net'92 conference in Washington D.C. to support
several application demonstrations including a packetized video
application. Interactive videoconferencing sessions were sustained
Cooper [Page 24]
Internet Monthly Report March 1992
across the T3 network between MCNC in North Carolina and the Net'92
conference in Washington.
There are several T3 BGP routing software enhancements that were
developed and tested during March for deployment in April. These
include interpretation of different Inter-AS external metrics,
improved version negotiation, and improved aggregation of networks
into a single update.
We have encountered a few T3 problems during March. There is a
memory leak bug in the SNMP daemon running on the T3 nodes that
causes a very slow increase in memory utilization over time. This
has caused some nodes to suffer from problems wih paging space, and
route daemon problems. A workaround has been applied until a bug
fix is provided for this.
We have had several RS6000 FDDI adapter problems during March where
the adapter will freeze. We experienced this at Pittsburgh
following a facilities problems that caused high temperature
conditions. We have also observed similar intermittent FDDI
adapter problems at San Diego (ENSS135), Champaign (ENSS129), and
Palo Alto (ENSS128). Each of these adapters has been replaced. We
expect to replace all RS6000 FDDI adapters with a new higher
performance/reliable adapter during the summer. We have also
experienced an RS6000 ethernet interface freeze problem at
Pittsburgh and FIX-E. We have replaced both of these interfaces
and will deploy a microcode bug fix to all ethernet adapters during
April.
T1 Network Status
=================
During March we continued to support changes on the T1 system to
reduce congestion and stability problems. Although we have
migrated a large fraction of traffic to the T3 system, we are still
observing stability problems due to increased routing complexity
and CPU problems on several RCP nodes. As we add more networks to
the T3 system we re-announce these networks to the T1 system at the
interconnect gateways. The IS-IS link state packet size being
computed is now over 25Kbytes at several locations. Additionally
the T1 network is supporting over 10 EGP peers at several locations
which increases the load on the RCP nodes. RCP-13-1 at Palo Alto
has suffered the most during March. These routing problems are
independent of traffic load on the PSP nodes.
We have made several changes to alleviate these problems. First, we
have implemented some performance improvements in the T1 routing
software and improved the coding efficiency of the T1 network LSP
Cooper [Page 25]
Internet Monthly Report March 1992
packets to reduce the size. The performance improvements have been
deployed and the LSP packet size compression will be deployed in
April. We have also upgraded several RCP nodes with faster RT/PC
processor cards. These cards will improve the RCP CPU performance
by about 30%.
Phase-III T3 Network Upgrade Plan Summary
=========================================
ANS & Merit are planning a major upgrade to the ANS/NSFNET T3
backbone service beginning in late April which is scheduled to
complete at the end of May. The upgrade involves changing all of
the T3 interface adapters in the RS/6000 T3 routers as well as the
DSUs. The new T3 adapter (called RS960) supports on-card packet
forwarding which will dramatically improve the performance, as
packet forwarding will not require support by the main RS6000 CPU.
The mechanism used will allow a T3 adapter to send data directly to
another adapter across the RS6000 bus. The reliability of the new
RS960 adapter is much greater than the existing T3 adapter (known
as "Hawthorne T3 adapter").
We will also upgrade the DSU to provide "C-bit parity" over the T3
links. C-bit parity (based on ANSI T1.107A spec.) will provide
improved end-to-end real-time link level network management
information. C-bit parity is conceptually comparable to Extended
Super Framing (ESF) over T1 circuits. Other minor changes on the
router include the replacement of the fan, the I/O planar card, and
associated cabling to support the adapter upgrade.
The result of this upgrade will be higher speed packet switching
and increased SNMP functionality, better T3 link monitoring, higher
T3 router reliability and availability, better diagnostic and
repair capability as well as improved statistical monitoring
support.
The deployment of this upgrade will temporarily affect T3 network
connectivity while the core node (CNSS) and end node (ENSS) routers
are upgraded. In order to minimize down time, all nodes will be
upgraded during off-hours on weekends.
The target start date for the phase-III upgrade is April 24. This
is contingent upon successful completion of the test plan described
below. Implementation of the deployment is planned to cover six
steps, each step taking place over a Friday night/Saturday morning
8 hour window. Each step will correspond to the upgrade of all
CNSS's located at two adjacent POPs and all of the T3 ENSS nodes
supported by those CNSS's. T3 network outages at NSFNET midlevel
T3 network sites are expected to average 2 hours per step, although
Cooper [Page 26]
Internet Monthly Report March 1992
we have provisioned an 8 hour window to accomplish the upgrade to
the T3 ENSS and adjacent CNSS nodes. NSFNET T3 midlevel networks
will be cut over to the T1 backbone prior to the scheduled upgrade
and will remain on the T1 until the affected nodes are upgraded and
network reachability has been successfully re-established.
During the outage period where the T3 CNSS routers are upgraded
(expected to be 2 hours), traffic from other T1 and lower speed
ENSS nodes, as well as T1 CNSS transit traffic will be continue to
be routed via the T1 safetynet circuits.
All upgrades will start on a Friday night, with a starting time of
approximately 23:00 EST. There will be two exceptions: changes to
the Denver and Cleveland facilities will be starting at
approximately 24:00 local time. Each CNSS site should take about 8
hours to complete, with the exception of the New York City core
node. At the New York City site, we will also be physically moving
the equipment within the POP and expect this move to add about 4
hours to the upgrade there. Although each upgrade is expected to
require 8 hours to complete, we are reserving the entire weekend,
approximately 23:00 local time on Friday to 24:00 local time on
Sunday, for possible disruptions to service. This window will
allow enough time to debug any unforeseen problem that may arise.
A second visit to core nodes will be required to replace a single
remaining old-technology T3 adapter. This will result in a T3
outage of approximately 105 minutes at sites as indicated below.
We have established a tentative upgrade scheduled which is
contingent upon successful completion of all testing (described
below). The current upgrade schedule has been distributed to the
regional technical liasons.
It is anticipated that with the exception of the T3 ENSS indicated
site outages other ENSS nodes and transit traffic services will be
switched across the safetynet and T1 CNSS concentrators during the
upgrades. However brief routing transients or instabilities may be
observed. NSR messages will be posted 48 hours in advance of any
scheduled changes and questions or comments on the schedule or plan
may be directed to the ie@merit.edu mailing list.
T3 Research Network RS960 Test Plan and Experiences
===================================================
This upgrade is the culmination of several months of development
and lab and network testing of the new technology. Many of the
problems identified during the deployment of the phase-II T3
network have been corrected in the new hardware/software. A
summary of the experiences we have had with this technology on the
Cooper [Page 27]
Internet Monthly Report March 1992
T3 Research network is described below.
ANS/Merit and their partners maintain a full wide area T3/T1
Research network for development and testing of new hardware,
software, and procedures prior to introduction on the production
networks. The T3 Research network includes 3 core node locations
with multiple fully configured CNSS routers. There are 5 ENSS
sites at which we maintain full T3 ENSS routers as well as local
ethernet and FDDI LANs that interconnect multiple peer routers and
test hosts. These test network is designed to emulate the
production network configuration as much as possible. The wide
area Research network interconnects with multiple testbeds at each
of the 5 ENSS locations. These testbeds are configured to emulate
regional and campus network configurations.
General Testing Goals and Methods
---------------------------------
Unit and system testing of all phase-III technology is conducted
first in the development laboratories, and then regression tested
on the development testbeds at each of the participating sites.
The primary goal for testing of the phase-III technology on the T3
Research network is to determine whether the new technology meets
several acceptance criterion for deployment on the production
network. These criterion include engineering requirements such as
routing, packet forwarding, manageability, and fault tolerance.
They also include regression testing against all known problems
that have been corrected to date on the T3 system, including all of
its components.
The following are secondary goals that the test plan includes:
1. To gain experience with new components so that the NOC and
engineering staffs can recover from problems once in production.
2. To identify any problems resulting from attempts to duplicate
production network traffic load and distributions on the Test
Network.
3. To perform load saturation, route flapping, and other stress
tests to measure system response and determine failure modes
and performance limits.
4. To duplicate selected system and unit tests in a more
production-like environment.
5. To design and execute tests and that reflect "end-user
perceptions" of network performance and availability.
Cooper [Page 28]
Internet Monthly Report March 1992
6. To isolate new or unique components under test to evaluate new
criterion or performance objectives for testing those specific
new components. Regression testing against the entire system
is also emphasized.
7. To independantly evaluate the validity of specific tests to
ensure their usefulness.
Phase-III Components to be tested
=================================
The RS960 interface upgrade consists of two new hardware
components:
1. RS960 DS3/HSSI interfaces
2. New T3 DSU adapters

Phase-III Test Experiences and Results To-Date Summary
======================================================
Testing is scheduled to continue up until 4/17. We will then
freeze the test network in preparation for deployment on 4/24.
Testing will continue throughout the deployment.
Overall Testnet Observations
----------------------------
The performance of the RS960 technology is far superior to that of
the existing Hawthorne T3 adapter technology. Although peak
performance throughput tests have not yet been conducted, the
steady state performance for card-card transfers has been measured
in excess of 20KPPS with excellent stability.
During the early deployment of the RS960 and DSU technology on the
testnetwork, we observed several new transmission facility problems
that were not observed in the lab tests, or in earlier DS3 adapter
tests. We found a new form of data pattern sensitivity where under
certain conditions the new DSU can generate a stream of 010101 bits
that induce an Alert Indicator Signal (blue alarm) within the MCI
network.
The RS960 and existing Hawthorne T3 card do not interoperate over a
serial link. However they will interoperate if both are installed
within a single CNSS node using specially developed driver software
which uses the main RS6000 CPU for packet forwarding between the
RS960 and Hawthorne T3 cards. As part of the phase-III migration
period we had originally planned to support an interim CNSS
configuration of 3xHawthorne T3 adapters and 1xRS960 adapter as
well as a 1xHawthorne T3 & 3xRS960 T3 interim CNSS configuration.
Unfortunately during the performance tests we determined that the
3xHawthorne T3 & 1xRS960 T3 configuration creates a performance
bottleneck that could cause congestion under heavy load. This is
due to the interim state RS960 <-> Hawthorne interface software
driver bottlneck where the main RS6000 CPU is used for packet
forwarding between dis-similar adapters. We have therefore
eliminated this configuration from the deployment plan and will
support only the 1xHawthorne, 3xRS960 configuration as an interim
state during the deployment. We are also looking various
deployment strategies that will avoid any congestion across an

T3 link metric adjustment, safetynet link load splitting, careful
placement of these transition links to avoid hot-spots, or
temporary addition of new DS3 links that will short-cut these
transition links.
We are using something called a copy tool that was developed as a
host system that interfaces on a production network ethernet, and
test network ethernet whereby all production ethernet packets are
promiscuously copied on the host, given a new destination address,
and injected into the Research network to simulate production
traffic flows within the Research network. We have found a bug in
the copy tool that has caused problems on the test ethernets at a
couple of Research network locations. Everytime the copy tool is
re-booted, we experience congestion on the test ethernets due to an
erroneous broadcast of a copied packet onto a test ethernet. We
are fixing this problem before we run these tests again.
We have run numerous route flapping tests where will install and
delete routes repeatedly on all installed RS960 cards and have not
encountered any chronic problems so far. The installation and
deletion of 6000 routes on the card is fast enough that we can not
measure an inconsistencies between different on-card route tables.
We have compiled a limit of 6000 routes on the card for now since
this reflects the deployment configuration, however we can support
up to 14000 IP routes on the card if necessary.
We have opened and closed over 100 problems during the several
months of lab and Research network testing on RS960. There are
currently 14 open problems remaining from our tests to date and we
can provide some details on this for anyone interested. We have
fixes for most of these problems that will be regression tested on
the Research network next week. We expect to close these problems
prior to deployment of RS960 on 4/24.
NSFNET/INFORMATION SERVICES
---------------------------
Networks configured for announcement on the NSFNET infrastructures
number 4,976 at the end of March, 1992. Of this total, 2,721
networks are configured for announcement on the T3 backbone, and
1,697 networks are located outside of the United States. March
packet traffic on the NSFNET is discussed in the NSFNET/ANSNET
Backbone Engineering report to the Internet Monthly Report.
The March meeting of the IETF in San Diego, CA was well attended by
Merit/NSFNET staff: Ellen Hoffman and Pat Smith of Information
Services; Jessica Yu, Elise Gerich, Sue Hares, and Mark Knopper of
Internet Engineering; Dale Johnson and Andrew Adams of Network

Management Systems. Hoffman and Smith continued their activities
as co-chairs of their respective User Services working groups, and
Yu chairs the BGP Deployment working group. Hares, Gerich and Yu
also participate in the Routing and Addressing (ROAD) working
group. Gerich was the Merit Internet Engineering representative to
the IEPG, which also convened in San Diego.
Ken Horning of Merit spoke at the Online Computer Library Center
(OCLC) in Dublin, Ohio. "NREN: Light at the end of a long tunnel,"
a one-day conference, was sponsored by OhioNet and attended by
librarians and information services staff from several midwestern
states. Horning presented an overview of the NSFNET project,
including recent network use statistics, as well as highlighting
the role the NSFNET is envisioned to play in the evolving National
Research and Education Network (NREN).
The Coalition of Networked Information held the Spring 1992 Meeting
of the Coalition Task Force in Washington, DC. Ellen Hoffman,
manager of Merit/NSFNET Information Services, and Laura Kelleher
participated in the various sessions. The TopNode Internet
directory project was officially announced at the proceedings.
Merit will be working with Indiana University on TopNode, with
responsibilities to include sharing knowledge about network
resources, assisting in the gathering of such information, and
creating an X.500 version of the TopNode directory. In keeping with
the meeting theme, "Network Navigating and Navigators," Merit
Network, Inc. introduced its "Cruise of the Internet," with the
gracious cooperation of CNI.
The "Cruise" is an interactive instructional guide to the Internet.
The Introduction section compares the Internet to an ocean. In the
Navigation Tools section, some of the tools which can help navigate
the Internet (e-mail, FTP and Telnet) are introduced. The
Applications section includes several examples of how people are
using Internet resources and how to access those resources. Created
by Steve Burdick of Merit Network, Inc. using MacroMind Director
for the Macintosh, the Cruise is based on a presentation written by
Laura Kelleher and Mark Davis-Craig, also of Merit. A Windows
version is being planned.
The beta version (1.0.B) of Merit Network's "Cruise of the
Internet" is being distributed without charge for evaluation and
use. The Cruise is available for anonymous FTP as a self-extracting
archive (.sea). To extract the Cruise and run the presentation,
system requirements are:
A Macintosh II or Quadra series computer
8-bit color and any color monitor (13" minimum recommended)

National Net '92, "Advancing the Leading Edge," convened at Loews
L'enfant Plaza Hotel in Washington, D.C. March 25-27. The NSFNET
partnership provided connectivity for several demonstrations. Phil
Hirt of the Merit Network Systems Hardware Support group deployed
and managed the LAN. Bill Norton, of Merit's Network Management
Systems group, demonstrated "discoveryRover," one of the primary
tools used by the Merit NOC to monitor the NSFNET and written by
Norton. The demonstration showcased the graphical interface to
Rover which builds the topology display of the network from a
network status file. Node and link state changes are reflected in
color changes on the X Windows-based display. Merit/NSFNET and
FARNET hosted "The Internet in Action," an exhibition of tools to
navigate Internet resources, including WAIS, Gopher, Cleveland
Freenet, and Merit's "Cruise of the Internet." Attending on behalf
of the Merit/NSFNET Project were Eric Aupperle, President of Merit
Network, Inc.; Jim Williams, Merit Associate Director for National
Networking; Ellen Hoffman, manager Merit/NSFNET Information
Services; Steve Burdick, Laura Kelleher and Pat Smith, Information
Services; Mark Davis-Craig and Dana Sitzler, Merit Technical

PITTSBURGH SUPERCOMPUTER CENTER
-------------------------------
The PSC is proud to announce the arrival of our next generation of
massively parallel computer, the Thinking Machines Connection
Machine, CM-5. The new machine currently with 4 gigabytes of
memory distributed among it's 256 processing nodes, has the most
memory of any machine currently available to the users of the NSF
centers. Plans for future expansion of the machine include
floating point pipelines and a doubling of the memory that will
enable it to do 32 gigaflops.
We established a live video link to the site where the CM-5 was
installed so that we could view the install back at home. The
system consisted of a Sony Camera attached to a Sun Sparcstation 1+
at the install site that communicated via ethernet and fiber to
another Sun at our home site. This second machine multicasted to
workstations locally, reducing the redundancy of information pumped
over the long haul.
Matt Mathis, Gene Hastings and Ken Goodwin took part in this
month's IETF meetings in San Diego. Matt presented his work with
BGP Usage at the PSC to the BGP Ultilization Session. Gene chairs
the Network Joint Management group and moderates the Network Status
Reports group. He also participated in the User Connectivity,
Operations Area Directorate, Internet School Networking and BGP
Utilization groups. Ken participated in the Op-Stats and Router
Performance Measurement working groups.
Gene attended the FARNET workshop on the hardening of the Internet
in February. The group plans to produce a report and set of
recommendations to the NSF. Gene agreed to take part in a
committee that will produce the final report from notes taken
during the meetings. Also in February, Gene and Ken attended

SAIC
----
We have started planning for the IDPR gated experiment. We have
contacted MITRE to see if they will be able, like before, to to
provide us with their Internet test environment. We also have
responses from several users on the Internet who would like to
participate in the experiment. We would like to include as many
users as possible, and we are looking for ways to change gated
implementation to support a "half-gateway" configuration. This
will enable one physical gateway to act as an IDPR virtual gateway
(VG), and hence reduce the number of resources, at one site,
required for the experiment.
We have had discussions with Mark Sleeper to identify how to
incorporate network management experiments. We have concluded that
the code previously written for the management agent needs to be
revised for interface to the IDPR gated module. We will decide
later what parameters in IDPR want agent to control. The original
agent was CMIP based, however the GATED implementation of IDPR will
mostly likely use SNMP, since the SMUX support is readily
available. One path being pursued is a CMIP agent that will use
SNMP based access routines.
Z. Avramovic has written a position paper, currently under review
by D.Mills, that suggests some reduction of IDPR complexity. She
is also analyzing CLNP and ENCAPS, two proposals forwarded to the
IETF, that suggest ways to augment or change Internet address
space. The purpose of the analysis is to determine how compatible
is IDPR architecture with either of the proposals.
Integration of the VGP module was begun, however there is some
mismatch between the old VGP code and the new BBN database that
requires some creative use of the database information and the
addition of some functions. However, the overall performance of
the GATED implementation will still be greatly enhanced by having
the single common database. The VGP as well as the CMTP code has
been modified, but remains untested.
Cooper [Page 36]
Internet Monthly Report March 1992
Planned Activities:
The complexity of the ISODE SMUX interface is still being
investigated. By the end of April we will have decided whether or
not we will use it. It appears that it should be fairly simple to
use, but the documentation is somewhat sketchy.
Chi Chu will update the IDPR kernel interface to support source
policies and will now use ioctl's rather than syscall's to provide
a more portable implementation. Woody Woodburn will be working on
the user level portion of the GATED implementation. Once VGP has
been tested, the SETUP module is the next candidate for
integration.

SESQUINET expanded to 37 member institutions with the addition of
South Coast Computing Services. The Texas State Technical College
is scheduled to be installed in April. SESQUINET has designated
Waco, TX as its 5th hub site.
Services
SESQUINET is now serving as an RFC repository. RFC's are available
from FTP.SESQUI.NET in the pub/rfc directory.
SESQUINET is planning to implement OSI/CLNP routing and has
received a block of registered addresses from the GSA. Please
contact hostmaster@sesqui.net for additional information.

A proposal for multimedia international services was circulated in
more polished form.
IETF Attendance -
Steve Hardcastle-Kille and Peter Kirstein attended the IETF in
person. Jon Crowcroft, Ian Wakeman and a cast of several from
Cambridge University and Edinburgh University attended as part of
the impressive Steve's Casner/Deering vat multicast to
ISI/BBN/DARTNET/OZ etc. UCL contributed the Multicast Assistance
Sender/Helper to forward UDP over parts of the Internet that cannot
adequately perform this function with Loose Source Routed IP. MASH
has been upgraded to take multicast packets and route them to
multiple unicat destinations (and vice versa!). It is ill-advised
to use it where loops may form!
We also successfully demonstrated medium speed colour video
conferenceing across (2Mbps) Janet to the annual Networkshop in
Leeds, with mono slow scan and audio again from London and to
Cambridge (Cambridgeshire). As part of a related excerscise, we ran
H.261 video between here and the British Telecom Labs in Ipswich,
with IP routers carrying other media over a separate B channel.
Note that we are now starting to field multicast as part of the UK
JANET IP Service infrastructure (albeit experimentally). We are
anxious that router vendors start supplying this as a normal
function.

UNIVERSITY OF DELAWARE
----------------------
February 1992 Report
1. Our packet-audio/video gear is working well and we are getting
used to having it around. Work is getting under way on
studying the networking-specific issues and, in particular, on
distributed algorithms for managing state and resource
commitment in the routers.
2. The problem that has prevented reliable acquisition of WWVB
time signals here has still not been found. FCC monitoring
stations in Maryland and Maine report identifying the critter
and locating it roughly in Quebec(!), but reports from New
England sites claim a clear signal and no problem acquiring
reliable time. I have concluded the FCC guys are chasing the
wrong bandit and in fact, the critter is nearby.
3. Work continues on checkout of the NTP Version-3 time daemon
implementation for Unix. It is now running on all net-128.4
munchkins here and on the DARTNET router at ISI, as well as a
number of alpha sites widely scattered on the globe. Because
of the problem noted above, DARTNET time service was rehomed
to ISI, where the WWVB signals appear to be clear.
March 1992 Report
1. The nice folk at Bancomm have loaned us a new product
combining a packaged GPS receiver and NTP primary time server
in a suitcase. Unfortunately, they forgot about gateway
support, so it talks only to our net-128.4 munchkins at
present. They are to fix that soon.
2. Our experimental, computer-controlled, LORAN-C receiver has
completed evaluation tests and measurements. A comprehensive
report, including analysis and design methodology, test
results, program listings and schematics, lurks in
pub/ntp/loran.tar.Z on louie.udel.edu.
3. We have liberated a Sun IPC to replace our four aging Fuzzball
time servers dcn1/2/5/6.udel.edu. Work is in progress to
rack-mount it and all our time machinery and resolve the pesky
problem of WWVB interference.

Internet Monthly Report March 1992
4. A preliminary (beta) distribution of the NTP Version 3 daemon
for Unix is in pub/ntp/xntp3.tar.Z on louie.udel.edu. This
distribution is intended for experimental use only and should
not be used for production service.
5. After one last, painstaking review and incorporation of minor
amendments, the NTP Version 3 specification document has been
submitted to the RFC Editor.

OSI IMPLEMENTER'S WORKSHOP (OIW)
--------------------------------
Since its last contribution to the Directory monthly report, the
OIW Directory Services SIG has met twice, once in December and once
in May.
SIG work in December focused on wrapping up 1991 work items, moving
profile text into Version 5 of the Stable Implementation Agreements
(SIA). Most of the newly stable text pertains to 1992 Directory
extensions for Replication (the new X.525 | 9594-9). It defines a
number of conformance classes for support of shadowing by
implementations, clarifies error handling in the new shadowing
protocol (DISP), and outlines a number of recommend practices for
shadowing DSAs.
SIG work in Directory access control per the 1992 extensions has
mostly been overtaken by the effort in the standards arena to
incorporate specific error handling into the base amendments, hence
there is no significant body of working text on access control
within the SIG.
A subgroup focusing on distributed operations has made twofold
progress -- first, it has worked to incorporate profiles on
distributed operations into SIA v.5 as of the March OIW; second, it
has been assisting with the definition of OSINET interoperability
test suites.
Also in March, the SIG repositioned itself to devote significant
effort to International Standardized Profiles (ISPs) for the
Cooper [Page 42]
Internet Monthly Report March 1992
Directory. ISPs are essentially alignments of certain core areas
of the Directory profile between the OIW and the other two regional
workshops (Europe and Asia-Oceania), and once agreed upon they are
published as ISO documents. John Dale from Corporation for Open
Systems has been acting as ISP editor on the SIG's behalf.
The current target for ISP draft submission in all areas is late
1992. Further work in editing/reviewing ISPs will take place at
the SIG's next meeting in June, but there is a meeting planned
between ISP editors from all three workshops for this May in
Ottawa, Ontario (in conjunction with the ISO/IEC SC21 conference at
the same location).
A working group aimed at profiling schema extensions in the 1992
edition of the Directory standard met for the first time at the
SIG's March meeting, and their work is expected to continue, with
any profile text on schema extensions becoming stable by the end of
the year.
Another March meeting activity was joint discussion with the MH
(X.400) SIG, focused on providing support for MHS use of the
Directory, and on where such support is lacking between 9594-
6|X.520, 10021-2|X.402, and the respective SIA, taken together. No
Workshop action has yet resulted from this, but a contribution from
the European workshop on attribute support for MHS will be reviewed
in further joint discussion between the two SIGs in June.
Finally, it is noteworthy that in 1992, US GOSIP will for the first
time include text on Directory Services. This text, which cites
the SIG's Stable Implementation Agreements on Directory, is
expected to be drafted by NIST in the very near future.
As a footnote, both Working and Stable Implementation Agreements,
for Directory Services (Part 11) and other protocols, are now
available for anonymous FTP at osi.ncsl.nist.gov, in both
WordPerfect and ASCII format. Effort to make them available in
PostScript format as well should bear some fruit shortly.
