Diameter Maintenance and Extensions (dime) ------------------------------------------ Charter Last Modified: 2007-02-26 Current Status: Active Working Group Chair(s): David Frascone Hannes Tschofenig Operations and Management Area Director(s): Dan Romascanu Ronald Bonica Operations and Management Area Advisor: TBD 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: Mar 2006 Submit Diameter API to IESG as an information RFC May 2006 Submit Diameter URI to IESG as an information RFC Sep 2006 Submit Diameter QoS Application to IESG as a Proposed Standard Sep 2006 Submit Diameter Application Design Guidelines to IESG as an informational RFC Jan 2007 Submit Diameter Base to IESG as a Draft Standard Internet-Drafts: Posted Revised I-D Title ------ ------- -------------------------------------------- Mar 2006 Feb 2007 The Diameter API Jun 2006 Feb 2007 Diameter Mobile IPv6: NAS <-> HAAA Support Dec 2006 Apr 2007 Diameter Base Protocol Feb 2007 Feb 2007 Diameter Quality of Service Application Request For Comments: None to date.
