DIAMETER

已更新:2022年1月16日

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 specifies 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.

History

This is the proposed successor of the RADIUS protocol.

Protocol dependencies

  • TCP: Typically, DIAMETER uses TCP as its transport protocol. The well known TCP port for DIAMETER traffic is 3868.

  • SCTP: Typically, DIAMETER uses SCTP as its transport protocol. The well known SCTP port for DIAMETER traffic is 3868.
