摘要
Diameter协议作为目前使用最广泛的AAA(认证、授权、计费)协议,可以应用于策略和计费控制(PCC)架构中。本文主要关注Diameter路由代理在PCC架构中的应用。文章总结了PCC架构功能和Diameter节点的基本特性,并对Diameter路由代理应用于PCRF寻址过程的场景进行了详细分析;同时,给出了Diameter路由代理的设计和性能测试方案。
As the most popular AAA （Authentication, Authorization and Accounting）protocol, Diameter protocol can he used in Policy and Charging Control （PCC） architecture. This paper focuses on the application of Diameter Routing Agent （DRA）in PCC. First of all, it summarizes the functions of PCC architecture and the basic features of Diameter peer. And then it makes analysis in detail about the usage of DRA in PCRF addressing. Also it gives a design for DRA, and scheme for testing the performance of different DRAs.
