The Diameter base protocol是用来提供一个AAA框架给像network access或者IP mobility的应用.

DIAMETER也用于工作在本地AAA和漫游情景下.

这个文档指定消息格式, 运输, 错误报告, accounting和用在所有DIAMETER应用的安全服务.

Diameter base 应用需要被所有的Diameter实现支持.

DIAMETER是RADIUS协议的推荐继承者.

Protocol dependencies 协议依赖

• 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.
