Diameter Maintenance and Extensions (dime) ------------------------------------------ Charter Last Modified: 2010-08-19 Current Status: Active Working Group Chair(s): Jouni Korhonen Lionel Morand 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.
