IAB MESSAGE
A. IAB/IETF NOW PART OF ISOC
Meeting in Kobe, Japan, on June 15, 1992, the Board of Trustees of
the Internet Society voted to accept a recommendation from the
Internet Activities Board to bring the IAB and all of its
activities into the Internet Society, with the IAB serving as a
technical advisory group of the ISOC. The IETF will continue to
pursue standards-setting and other engineering activities under
this new umbrella, and the IRTF will continue to pursue research
questions of importance to the Internet.
The IAB was renamed the Internet Architecture Board.
B. NEW POLICY ON POSTSCRIPT FOR STANDARDS DOCUMENTS
Since 1989, the Internet policy set by the IAB has allowed
Postscript RFC's but required that parallel ASCII versions exist as
well. The ASCII versions of Postscript have been allowed to be
substandard, e.g., missing diagrams and not meeting the customary
standards on format.
Experience has shown that that the results have been less than
satisfactory, and the IAB is now amending the policy in the
following manner: RFCs that document standards-track specifications
MUST have their reference text in ASCII. That is, the ASCII
version of standards-track specifications must be complete and
properly formatted. A secondary version in Postscript is still
allowed, but its Status of Memo will note that it is not primary.
No policy can be universal. If the drafters of a standards
specification RFC feel they have a legitimate need for using
Postscript for the reference version of a specification, they
should discuss this with the IESG, preferably early in the process.
Exceptions will not be granted lightly, but nothing is impossible.
This policy change affects only standards-track specifications;
other RFC's will continue to follow the former rules.
HISTORY AND BACKGROUND
In 1989, there was a raging discussion on the question of
Postscript RFCs, both on public mailing lists and within the IAB.
Based upon the public discussion, the IAB at its July 1989 meeting
agreed upon a dual-version policy. This was reflected in the
Instructions for RFC Authors and announced in the IAB REPORT
Cooper [Page 3]
Internet Monthly Report June 1992
[Internet Monthly Report, October 1989]:
"The IAB has noted the intense concern in the community about
Postscript-only RFC's; unfortunately, there is no ideal
solution for this problem. Until ODA or its equivalent is
widely available, some combination of ASCII and Postscript is
the best we can do. The IAB has instructed the RFC Editor to
obtain an ASCII version from the author of any Postscript-only
document whenever possible, and both versions are to be made
publically available. Although the dual versions may cause
significant extra work for both authors and editor, this
appears to be the only feasible compromise."
In the succeeding three years, the situation has not improved. ODA
has not saved us, and the drawbacks of Postscript noted in July
1989:
1) printing capability is not universal
2) difficult to cut and paste
3) difficult to search
4) file sizes are too large
5) unable to view from a terminal
are unchanged. Typically, we have found that the ASCII versions of
Postscript specifications have been derived mechanically, with
minimal or no editorial effort. The result has been unreadability
at best and at worst typographic errors in specifications where
precision is required and expected.
What has changed in three years is the economic significance of the
Internet standards process. As a result, the Internet community in
general and the IAB in particular have lavished a great deal of
time and effort to improve the quality of our standards process
while attempting to preserve its manifest virtues.
There is no question in anyone's mind that Postscript documents are
prettier and perhaps easier to read than corresponding ASCII
documents. However, we believe that other issues are paramount for
the formal specification of protocols and procedures. In
particular, a reference specification must be universally
printable, and it must be possible to cut-and-paste machine-
processable program fragments from the text. It should be possible
to easily search for desired text.
When fancy explanatory diagrams are desired, it may be appropriate
to create two documents, an introductory document in Postscript and
the formal specification in ASCII. We have a great deal of
experience with using ASCII to effectively document Internet
Cooper [Page 4]
Internet Monthly Report June 1992
protocols and procedures, and we believe that a carefully written
ASCII document can convey the desired information clearly and
precisely. It may be hoped that the restriction to a single font
will encourage authors to make every word count.
This policy was proposed to the IETF on May 28, 1992, and was very
extensively discussed on the IETF mailing list. The great majority
of comments received by the IAB were strongly in favor of this
change. Therefore, it was formally adopted by the IAB at its Kobe
meeting.

RESOURCE DISCOVERY AND DIRECTORY SERVICE
----------------------------------------
Several members of the research group have been discussing
conceptual and implementation relationships between Internet
resource discovery systems, towards the goal of supporting
seamless interoperation of resource discovery using multiple
underlying systems. To help analyze the problem, we are
developing a taxonomy with dimensions concerning resource
granularity, distribution, interconnection topology, and data
integration mechanism. This taxonomy provides inferences about
the ability of a system to support organizing, browsing, and
searching operations, and about what is needed to provide
gateways between individual systems.

ST Conferencing
During June, the TWB supported 8 point-to-point conferences, as
well as numerous test conferences. Test conferences were run
almost daily to bring up new sites, rehearse for demos, do
communications testing for exercises, and field test new software.
Floor control software has been deployed to 8 of the 18 video
gateway sites on the TWB. Deployments to the remaining sites are
continuing, although some sites have not yet provided Suns at their
locations, and so are unable to use floor control locally. The
first operational use of floor control was unsuccessful, due to an
incorrect hostname configured on a Sun at DARPA. DARPA
subsequently changed the hostname, and additional testing showed no
other problems.
Three TWB sites have been converted to secure installations for
demonstrations of E3 simulation and conferencing. These sites
(IDA, Ft. Rucker, and BBN-DWS) are no longer available for regular
conferencing on an ad-hoc basis. We do have the ability to switch
these sites, with appropriate warning, when necessary for important
non-secure activities. During a demonstration in June, IDA and
BBN-DWS successfully conducted a secure simulation demonstration
for a group at IDA.
During June, Ft. Knox, Ft. Rucker, and RADC converted from
butterfly to T/20 gateways. These were the last
conferencing/simulation sites to make the switch. Only two
butterfly gateways remain on the TWB.

GIGABIT NETWORKING
ATOMIC
The ATOMIC project took delivery of its first 3-by-3 interhost
router (Mosaic mesh) board. Functioning 8-by-8 mesh boards are
also now being tested at Caltech. This 3-by-3 router can directly
interconnect twelve hosts and should provide approximately 5 Gb/s
of routing capacity. AC, Mosiac and UNIX kernel work was done to
prepare for the use of N-by-N mesh routers in the ATOMIC network.
Router enclosure design and channel-cable adaptor board fabrication
were completed earlier this year. Assembly and initial testing of
the ATOMIC router prototype will begin in July. Testing will
determine mesh router capacity and will provide more interesting
topology for the ATOMIC discovery and routing database program, the
Address Consultant (AC).
Work on the AC in June centered on the automatic discovery and
display of network topology and detection/prevention of deadlocks.
The AC can now dynamically map the topology of ATOMIC networks and
create complete source-routing tables. Automatic interrogation of
the AC is implemented within the BSD UNIX kernel, to provide hosts
with source routes.
Multiple ACs can run simultaneously in different hosts. A
distributed election mechanism ensures that only one AC becomes the
"controlling" AC. The remainder remain dormant awaiting the
possible failure of the controlling AC, at which point a new
election occurs.
The issue of fault isolation for Mosaic channels in an office
environment was considered during June. A document that outlines
one approach toward isolation of channel faults was sent to
Caltech, where the Mosaic project is designing and prototyping a
many-meter Mosaic channel transmission chip. Fault isolation is
important since power failures, bugs, attacks and hardware failures
are a part of the real networking world.

MULTIMEDIA CONFERENCING
The initial implementation of the Connection Control Protocol (CCP)
was completed this month and will now be tested over DARTnet. CCP
is an experimental application layer protocol designed to
facilitate multimedia teleconferencing over the Internet. It
orchestrates multiple-user, multiple-media sessions in a
distributed manner, providing among other functions a flexible
group transaction service, robustness mechanisms for WAN operation
Cooper [Page 16]
Internet Monthly Report June 1992
and negotiation for heterogeneous end system configurations.
We are working with students from USC on software decoding of the
compressed video used in DARTnet experiments. Displaying video in
a workstation window rather than on a separate monitor facilitates
a "personal conferencing" mode. Software decoding will also enable
DARTnet experiments employing a larger number of receivers without
additional hardware cost. We have completed the decoding routines
which will be integrated with packet reception and X-window display
software by the students.
An article was submitted to Computer Communications Review on the
first IETF meeting "audiocast" from San Diego. Meanwhile,
preparations are underway for a second audiocast from the Boston
IETF in July, this time also including video and expected to reach
a much larger audience.

C. NETLOG, the JvNCnet Trouble Ticket System
"Netlog v2.0", a UNIX-based trouble-ticketing
system, is now in the public domain and available
from anonymous ftp:
(Username: your email address and no password).
ftp.jvnc.net under 'pub/netlog-tt.tar.Z'
All bug reports to "netlog-bugs@jvnc.net".
Send email to "netlog-users-request@jvnc.net" if you
use this software and want to receive software update
notification.
Running on Unix systems, Netlog, not based on any
database, stores all logs as ASCII text files and
its own index system processes the logs. Length of
log entry is unrestricted. Netlog uses an open, update,
close-ticketing, and informational mechanism. In use
at JvNCnet since 1990, the system is fast and efficient.
Netlog provides the following functions:
Create entry, edit log, read log, list open
tickets, search logs, process tickets
D. NOCOL, JvNCnet's Network Operation Center On-Line
NOCOL v2.0 is available in the public domain via
anonymous ftp from:
ftp.jvnc.net (128.121.50.7)
under ~ftp/pub/nocol.tar.Z.
For addition to the updates and bug fixes mailing list,
please send email to:
"nocol-users-request@jvnc.net".
Send comments to:
"nocol-info@jvnc.net"
Send bugs to:
"nocol-bugs@jvnc.net".
NOCOL, a collection of network monitoring programs, is
designed to run on Unix systems primarily for IP networks.
Monitoring agents poll various parameters from any system
and appropriately format the data for post-processing.
Post processors may be a display agent, automated
troubleshooting program, or event-logging program.
The display module (nocol) with the monitoring agents
is presently available.
Cooper [Page 19]
Internet Monthly Report June 1992
The monitoring agents can monitor any entity, protocol, or
variable. To date, the monitoring agents developed are:
IP ICMP monitor (ping or multiping)
OSI reachability monitor (OSI ping)
SNMP trap monitor
IP data throughput monitor
Nameserver (named) monitor
Monitor for number of terminal server lines in use
(for cisco terminal servers using xtacacs)
The software is flexible and permits enhancements and
development with minimal effort. It is easy to add
monitors for DECnet and/or other protocols. The program
was evaluated on SUNOS4.1.1, Ultrix, and NeXT.
Documentation is under "src/docs".
The JvNCnet display can be seen by logging into
"nocol.jvnc.net" as user 'nocol'. A "1 4" will give a
full display and 'h' will show a brief help screen.

LOS NETTOS
----------
We experienced an extended T1 outage on a redundant link because
GTE used type A Westel demarc's which would not respond to telco
loop up commands. GTE therefore wasted a lot of time trying to
repair the wrong end of the line.
GTE swapped out the type A Westels for a newer model that responds
to remote loop up commands.

NNSC, UCAR/BOLT BERANEK and NEWMAN, INC.
----------------------------------------
Cyndi Mills, Manager of the NNSC, participated in the INET '92
Conference in Kobe, Japan.
The NNSC (NSF Network Service Center) has begun a thorough-going
update of the Internet Resource Guide. In June, we distributed 18
new and updated entries. We are sending requests to our
contributors to revise and update their entries in the Guide,
beginning, with the oldest entries. The NNSC is actively seeking
new entries for the Resource Guide. If you know of a resource that
should be included, please send a message to "resource-
guide@nnsc.nsf.net" and we will be happy to send instructions and a
template to the address you suggest.
Cooper [Page 21]
Internet Monthly Report June 1992
We plan to produce a short version of the Guide as a companion to
the present guide. We will also continue the present format with
the modifications noted below. For the Compact Internet Resource
Guide, we are asking each contributor to prepare a ONE-LINER -- a
summary containing only the most essential description of the
Resource, in 72 characters or less. The Introduction to the
Compact Guide will direct the user who wishes to learn more to the
Resource Guide itself, and, at the contributor's option, to longer
documents.
The Internet Resource Guide has been very well received in the
Internet community. The Compact Guide should make it easier for
users to get an idea of the Resources that are available, and
encourage other Resource providers to contribute entries to the
Guide.
The NNSC is collecting updates from the mid-level networks for the
NSFNET site list for the next issue of the NSF Network Newsletter.
On June 8th, the Washington Post published an article on the
Internet. The NNSC Staff has received more than fifty requests for
information as a result of that article and we are still receiving
requests from the article "Applying the Internet" that appeared in
Byte Magazine last February.

NSFNET/ANSNET BACKBONE ENGINEERING
----------------------------------
T3 Backbone Status
==================
The T3 Backbone continued to run very reliably during June. With
the completion of the RS/960 DS3 interface upgrade in May, the
cutover of additional traffic from the T1 to the T3 network resumed
in June and is proceeding as quickly as possible. The number of
networks configured and announced to the T3 network continues to
increase. Midlevel traffic cut over from the T1 to the T3 backbone
included NorthWestNet, Sprint/International Connections Manager,
and Alternet. The T3 backbone is now carrying nearly double the
packet load of that of the T1 backbone.
With the upgrade complete and the T3 network stable, several
performance and functional enhancements have been administered
during June. Improvements to the routing daemon and SNMP daemon
were made. A remaining problem on the T3 network is the FDDI
adapter performance and stability. Due to the complexity of the T3
adapter upgrade, we chose to defer the FDDI upgrade until August to
ensure operational stability.
Cooper [Page 23]
Internet Monthly Report June 1992
Statistics on network traffic and configured networks
=====================================================
The total inbound packet count for the T3 network was
10,736,059,912,up 29% from April. 220,593,003 of these packets
entered from the T1 network. The total inbound packet count for
the T1 network was 5,761,976,518, down 16.7% from May. 536,009,585
of these packets entered from the T3 network. The combined total
inbound packet count for the T1 and T3 networks (less cross network
traffic) was 15,741,433,842, up 0.9% from April.
Currently there are 5801 IP networks configured in the policy
routing database for the T1 network, and 3966 for the T3 network.
Actual announced networks to the backbone varies and is currently
2750 for T3 and 4425 for T1.
NOC Problem Reports
===================
The number of problem reports that result in NOC trouble tickets
(total all priority classes) for the T3 network remains constant at
10-20 per week, and for the T1 network it remains at the 15-20 rate
per week.
T1 Backbone Status
==================
The T1 backbone's reliability is not as good as T3, due largely to
increased route processing on the RCP nodes. The full load of
routes is still being carried by these machines, and they are
experiencing congestion and performance problems to some degree.
Improvements have been made to the routing software to accomodate
protocol upgrades (ie. BGP2).
T3 Routing Daemon Software Status
=================================
Activities related to the rcp_routed software in June emphasized
correcting software problems involving routing instability, and
monitoring & correcting routing table integrity problems. There
were many bug fixes applied to the routing daemon over the last
three months.
Monitoring of routing integrity consists of data collection of the
full netstat table to find route flapping problems within the
backbone and within peer networks, BGP disconnect problems, and
external network metric problems. Additional work is underway to
collect full routing tables from backbone nodes to be processed
Cooper [Page 24]
Internet Monthly Report June 1992
using a relational database system. This system generates reports
on the statistical use of primary routes, reliability of network
announcements to the backbone, and long term statistics on inter-
domain routing announcements and growth.
A number of improvements and bug fixes have been made to the T3
routing software over the last two months. Highlights included: fix
to allow an ENSS that is isolated from the backbone to stop
announcing default to peers, better handling of router adapter
failures, preventing overruns of external BGP messages sent to
external peer routers, gracefully dropping bogus external routes to
backbone ENSS nodes, correct response to external metric selection
problem for nets announced at same metric from multiple peers,
problem with interaction between BGP and EGP for peers in the same
Autonomous System, hashing route table efficiency improvements, two
routes with same AS path are now both installed to allow backup,
BGP-2 PDU size increased from 1024 to 4096 bytes, route from BGP
and EGP with same metric now prefers BGP route, better handling of
next hop behind peer router and shared network, BGP update packet
format fix, fix to BGP 1-2 version negotiation, eliminated chance
of BGP disconnects during IGP transitions, eliminating BGP
disconnects if peer router is too busy, better response to route
instabilities upon failure of T1 interconnect or ENSS, and
autorestart of the routing daemon in the event of a crash.
As a result of the monitoring and analysis effort along with the
actual software changes, reliability and route integrity has
improved dramatically on the T3 network over the last month.
RS/960 DS3 On-Card Memory Problem
=================================
A batch of bad memory chips have been found to result in memory
parity errors on a few interfaces. Five of these cards have been
replaced as the problems have been identified. Diagnostic microcode
has been developed to detect the problems in advance, and nodes are
being scheduled for diagnostics to be run over the next few weeks
during routing configuration update scheduled windows.
DSU Synchronization and CRC/alignment Problem
=============================================
A problem that causes logical link failures has been traced to a
clock synchronization problem on the T3 Technologies DSU's during
clock master/slave transitions. This problem occurs very
infrequently and has been reproduced using a newly installed
circuit on the T3 research network. Enhanced instrumentation has
been added to detect this problem, and work is in progress to
Cooper [Page 25]
Internet Monthly Report June 1992
correct it.
End-To-End Packet Loss Analysis
===============================
Researchers at University of Maryland recently conducted some
experiments and noticed periodic and random packet loss and packet
duplicates when using the T3 network. There were two problems
traced to a bridge device and an ethernet problem on the SURAnet
ethernet. Peer router problems causing some packet loss during
routing updates at NEARnet were identified and are being corrected.
Also some packet loss on the T3 ENSS FDDI interface at Stanford was
identified. This is due to an FDDI card output buffering problem
and might be addressed prior to the FDDI upgrade in August.
FDDI Adapter Upgrade
====================
Although the T3 adapters have been upgraded from older technology
to the new RS960 adapter technology, the FDDI adapters in the ENSS
nodes have not yet been upgraded. The older FDDI adapters continue
to suffer from performance on reliability problems.
The new RS960 FDDI adapter is scheduled to be installed as part of
a field trial on July 20th. Following this field trial, we expect
to upgrade the older FDDI interfaces with the new RS960 interface
adapters in early August. There are currently five T3 ENSS sites
that are using FDDI interfaces in production.
SNMP Daemon Changes
===================
A new version of the SNMP daemon for the T3 network was installed
on June 26. This version supports MIB-II variables for the T/960
ethernet cards (ifInUcastPkts, ifOutUcastPkts, and ifInErrors), and
also includes enhanced configuration support for monitoring T3
DSUs.
A new SNMP client for the NOC to control the T1 Cylink ACSUs which
are part of the T3 backbone has been implemented. This avoids use
of a separate dial-in connection to these CSUs.
New SNMP variables have been added to furthermonitor the DSU
synchronization problem mentioned above.

1. The end2end research group meeting was held at the University
of Delaware on 9-10 June.
2. Measurements continue with the NTP version-3 daemon for Unix
as modified to support a one-pulse-per-second signal generated
by some timecode receivers and precision oscillators.
Preliminary results were presented at the end2end research
meeting. While incidental jitter has been reduced to a few
tens of microseconds, the frequency stability, typically a few
parts in 10**7, is limited by the oscillator wander and
crystal aging found in typical computer clocks.
3. A comprehensive technical report on precision computer
timekeeping can be found on louie.udel.edu in the compressed

PostScript format and are rich in diagrams and equations.
4. Our burgeoning antenna farm at two sites now feeds two WWVB
timecode receivers, three WWV receivers, two GPS receivers,
two LORAN-C receivers and a CHU receiver. Aging fuzzball
primary time server dcn1.udel.edu has been replaced by a
dedicated Sun IPC at the same address and synchronized to

NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY
----------------------------------------------
During June the Pilot DSA was up and running almost continuously.
Starting in July, we will collect statistics on Pilot usage. These
will be reported beginning in August.
Work has progressed on extending the scope and accessibility of the
Pilot. An account has been set up to enable dialup DUA access for
other agency staff. On login, the Widget DUA user interface is
automatically brought up, providing access to the Pilot DSA. Some
details remain to be worked out, but dial-up access is expected to
begin by the end of July.
We are continuing to pursue TP4/CLNP accessibility to the Pilot DSA
over FTS A and B. The impediments have to do with establishing an
OSI routing path from the NIST FTS access machine to the machine
running the Pilot DSA.

Internet Monthly Report June 1992
NIST X.500 Implementation
-------------------------
Improvements were caried out in two areas of the Custos code during
June. A problem with the result of the List operation, in which the
origin of the information carried in the result was incorrectly
flagged, was corrected, and the code for the Search operation was
enhanced to enable Search to operate on all naming contexts,
regardless of whether the naming context has been loaded into
memory at startup.
Future Plans
------------
We have continued our work with NASA, DHHS, and other agencies to
establish Internet and FTS2000 connectivity to the pilot DSA. We
have begun a dialog with Dallas Day of Wright-Patterson AFB on the
integration of his base's OSIWare DSA into the Pilot, and have had
similar discussions with Doug Harsha from the Department of
Agriculture in Ft. Collins, CO. We have also initiated discussions
with NIST's Computing and Applied Mathematics Laboratory on a
collaborative venture to provide a NIST-wide white pages directory
service. The plan is to provide telephone/email/addressing
information on NIST staff to the desktop, via PC and Macintosh
based DUA packages. We expect that this can serve as a model for
other agencies interested in deploying the OSI Directory.
