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.
