Diameter Maintenance and Extensions (dime) ------------------------------------------ Charter Last Modified: 2011-12-09 Current Status: Active Working Group Chair(s): Jouni Korhonen Lionel Morand Operations and Management Area Director(s): Dan Romascanu Ronald Bonica Benoit Claise 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, charging in network access, provisioning of configuration information within the network, and for new AAA session management uses within the extensibility rules of the Diameter base protocol. The DIME working group plans 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. - 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. - 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. - Protocol extensions for bulk and grouped AAA session management. The aim of this work is to study and standardize a solution for handling groups of AAA sessions within the Diameter base protocol context. The solution would define how to identify and handle grouped AAA sessions in commands and operations. Additionally, Diameter-based 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, and is within the extensibility rules of Diameter and AAA scope. Coordination with other IETF working groups and other SDOs (e.g. 3GPP) will be used to ensure this.
