 Working Group: Diameter Maintenance and Extensions (dime)
 Formats: txt
In large network deployments, a single Diameter node can support over a million concurrent Diameter sessions. In some use cases, Diameter nodes need to apply the same operation to a large group of Diameter sessions concurrently. The Diameter base protocol commands operate on a single session so these use cases could result in many thousands of command exchanges to enforce the same operation on each session in the group. In order to reduce signaling, it would be desirable to enable bulk operations on all (or part of) the sessions managed by a Diameter node using a single or a few command exchanges. This document specifies the Diameter protocol extensions to achieve this signaling optimization.

Charter for 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 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.

- 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.

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.
