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.
