Diameter Maintenance and Extensions (dime) ------------------------------------------ Charter Last Modified: 2009-01-07 Current Status: Active Working Group Chair(s): Hannes Tschofenig David Frascone Operations and Management Area Director(s): Dan Romascanu Ronald Bonica Operations and Management Area Advisor: Dan Romascanu Secretary(ies): Victor Fajardo Mailing Lists: General Discussion:dime@ietf.org To Subscribe: https://www1.ietf.org/mailman/listinfo/dime Archive: http://www.ietf.org/mail-archive/web/dime/index.html Description of Working Group: The Diameter Maintanence and Extensions WG will focus on maintenance and extensions to the Diameter protocol required to enable its use in applications such as IP telephony and Local Area Network authentication, authorization and accounting. The IETF has recently completed work on the Diameter Base protocol. There is on-going work on defining RADIUS extensions. The work done in the DiME WG will ensure that work done in RADext is also available for Diameter. The immediate goals of the DiME working group are to address the following issues: - Maintaining and/or progressing, along the standards track, the Diameter procotol and Diameter Applications. Every revised document to be "maintained" requires explicit approval before it will be accepted as a WG document. - An informational RFC on a Diameter API. - Diameter Application design guidelines. This document will provide guidelines for design of new Diameter Applications. It will detail when to consider reusing an existing application and when to develop a new application. Interaction between vendor & SDO specific extensions and applications will be covered. - Diameter QoS application. This document will develop a new Diameter application for supporting QoS in AAA deployments. The NSIS WG will be consulted on proper design of QoS attributes. - Diameter URI. RFC 3588 defines an AAA URI which has some known problems. A document revising the AAA URI as a specific Diameter URI will be developed. - Diameter extensions for MIPv6. This may include support for Mobile IP extensions, like FMIP; as well as support for MIP bootstrapping. Additionally, AAA systems require interoperability in order to work. Uncontrolled extensibility is not a mechanism for interoperability. Therefore, the working group, along with the AD, will need to evaluate any potential extensions and require verification that the proposed extension is needed. Coordination with other IETF working groups and other SDOs will used to ensure this. Goals and Milestones: Done Submit the following two Diameter Mobility documents to the IESG for consideration as a Proposed Standards:* 'Diameter Mobile IPv6: Support for Home Agent to Diameter Server Interaction' * 'Diameter Mobile IPv6: Support for Network Access Server to Diameter Server Interaction' Done Submit 'Diameter API' to the IESG for consideration as an Informational RFC Done Submit 'Quality of Service Parameters for Usage with Diameter' to the IESG for consideration as a Proposed Standard. Jan 2009 Submit Revision of 'Diameter Base Protocol' to the IESG for consideration as a Proposed Standard Jan 2009 Submit 'Diameter QoS Application' to the IESG for consideration as a Proposed Standard Jan 2009 Submit 'Diameter Support for EAP Re-authentication Protocol' as DIME working group item Jan 2009 Submit 'Diameter User-Name and Realm Based Request Routing Clarifications' as DIME working group item Jan 2009 Submit 'Diameter Proxy Mobile IPv6' as DIME working group item Jan 2009 Submit 'Quality of Service Attributes for Diameter' to the IESG for consideration as a Proposed Standard Mar 2009 Submit 'Diameter Application Design Guidelines' to the IESG for consideration as a BCP document Apr 2009 Submit 'Diameter Proxy Mobile IPv6' to the IESG for consideration as a Proposed Standard Apr 2009 Submit 'Diameter User-Name and Realm Based Request Routing Clarifications' to the IESG for consideration as a Proposed Standard May 2009 Submit 'Diameter Support for EAP Re-authentication Protocol' to the IESG for consideration as a Proposed Standard Internet-Drafts: Posted Revised I-D Title ------ ------- -------------------------------------------- Mar 2006 Jul 2008 The Diameter API Jun 2006 Dec 2008 Diameter Mobile IPv6: Support for Home Agent to Diameter Server Interaction Jun 2006 Jan 2009 Diameter Mobile IPv6: Support for Network Access Server to Diameter Server Interaction Dec 2006 Dec 2008 Diameter Base Protocol Feb 2007 Dec 2008 Diameter Quality of Service Application May 2007 Nov 2008 Diameter Applications Design Guidelines Jun 2007 Dec 2008 Quality of Service Parameters for Usage with Diameter Jul 2007 Dec 2008 Quality of Service Attributes for Diameter Jan 2009 Jan 2009 Diameter Proxy Mobile IPv6: Support For Mobile Access Gateway and Local Mobility Anchor to Diameter Server Interaction Jan 2009 Jan 2009 Diameter User-Name and Realm Based Request Routing Clarifications Request For Comments: None to date.
