Diameter Maintenance and Extensions (dime) ------------------------------------------ Charter Last Modified: 2009-07-07 Current Status: Active Working Group Chair(s): Hannes Tschofenig Victor Fajardo Operations and Management Area Director(s): Dan Romascanu Ronald Bonica Operations and Management Area Advisor: Dan Romascanu Mailing Lists: General Discussion:dime@ietf.org To Subscribe: https://www.ietf.org/mailman/listinfo/dime Archive: http://www.ietf.org/mail-archive/web/dime/current/maillist.html Description of Working Group: The Diameter Maintenance and Extensions WG will focus on maintenance and extensions to the Diameter protocol required to enable its use for authentication, authorization, accounting and provisioning in network access as well as for other applications environments (e.g., IP telephony, mobility). The IETF has completed work on the Diameter Base protocol and is working on revising the base protocol specification. There is on-going work on defining RADIUS extensions and the DIME WG will ensure that work done in RADEXT is also available for Diameter. The DIME working group plains to address the following items: - Maintaining and/or progressing, along the standards track, the Diameter Base protocol and Diameter Applications. This includes extensions to Diameter Base protocol that can be considered as enhanced features or bug fixes, such NAI routing or capability update extensions. - Diameter application design guideline. This document will provide guidelines for design of Diameter extensions. It will detail when to consider reusing an existing application and when to develop a new application. - Diameter QoS extensions. This work focuses on extensions to Diameter to support QoS information to be authorized and provisioned in AAA deployments. - Protocol extensions for the management of Diameter entities. This work focuses on the standardization of Management Information Bases (MIBs) to configure Diameter entities (such as the Diameter Base protocol or Diameter Credit Control nodes). The usage of other management protocols for configuring Diameter entities may be future work within the group. - Diameter extensions for mobility protocols, such as Mobile IPv6 and Proxy Mobile IPv6. Diameter extensions to support handover keying developed in the HOKEY WG are part of this effort. - New Diameter applications, such as the Diameter NAT control application. This group will also conduct work on new Diameter applications with a Diameter application for configuring NATs as the first item. Additionally, AAA systems require interoperability in order to work. 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 Apr 2009 The Diameter API Jun 2006 Apr 2009 Diameter Mobile IPv6: Support for Home Agent to Diameter Server Interaction Dec 2006 May 2009 Diameter Base Protocol Feb 2007 May 2009 Diameter Quality of Service Application Jun 2007 May 2009 Quality of Service Parameters for Usage with Diameter Jul 2007 Jun 2009 Quality of Service Attributes for Diameter Jan 2009 May 2009 Diameter User-Name and Realm Based Request Routing Clarifications Jan 2009 Apr 2009 Diameter Proxy Mobile IPv6: Mobile Access Gateway and Local Mobility Anchor Interaction with Diameter Server Jan 2009 Jan 2009 Diameter Support for EAP Re-authentication Protocol May 2009 Jul 2009 Diameter Credit Control Application MIB May 2009 Jul 2009 Diameter Base Protocol MIB Jun 2009 Jun 2009 Updated IANA Considerations for Diameter Command Code Allocations Request For Comments: RFC Stat Published Title ------- -- ----------- ------------------------------------ RFC5447 PS Feb 2009 Diameter Mobile IPv6: Support for Network Access Server to Diameter Server Interaction
