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 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.
- Diameter overload control. The aim of this work is to identify the limitations
of the Diameter protocol level overload control provided by the current
Diameter Base protocol. A set of requirements will be provided to define a
new Diameter level overload control mechanism.
