Diameter AAA, Authentication
Authorization and Accounting

Diameter is the proposed successor of the RADIUS protocol.

Diameter Technical Specification, ITEF RFC3588

The Diameter base protocol is intended to provide an Authentication, Authorization and Accounting (AAA) framework for applications such as network access or IP mobility. Diameter is also intended to work in both local Authentication, Authorization & Accounting and roaming situations. This document pecifies the message format, transport, error reporting, accounting and security services to be used by all Diameter applications. The Diameter base application needs to be supported by all Diameter implementations.

openDiameter Open Source Project

The open-source Diameter implemenation protocol is based on RFC3588 designed by the IETF's AAA Working Group. The work has been continued by the IETF DIME (Diameter Extension) WG and its activities can be found at the DIME Activities.

The source code of the Open Diameter software is available under the combination of Lesser GNU Pulic License and GNU Public License. The base protocol implementation available as a C++ library and has currently support Linux, BSD and Windows systems. It relies on ACE to provide system level abstraction for all supported systems. Further documentation is available at sourceforge documentation page.
