摘要
安全、有效、可扩展的认证/计费服务的设计是VoIP系统中的一个重要组成部分,就独立认证/计费系统的结构进行了说明,并就VoIP系统中如何利用Radius协议提供的认证/计费服务进行安全的数据包交换进行了剖析,给出了认证/计费系统实现流程。为了减少系统的响应时间和认证的差错率,采用一种双队列、无状态的流水线技术设计了一个基于Radius协议的VoIP认证/计费系统,同时对后台数据库的设计和功能实现做了必要说明。
The design of reliable, secure, extensible authentication and accounting system is an important part in implementing a VoIP system, The independent architecture of VOIP authentication and accounting system is presented, and how to make use of the service of authentication and accounting offered by Radius protocol to implement package data exchange in a secure way is analyzed, and the process of authentication and accounting system is brought forward. To lower the response time and authenticating error ratio, a VoIP authentication and accounting system based on the Radius protocol is designed by adopting a technology of two-queue stateless pipelining. In addition, some necessary explains to the main design principals and functions of the database is given.
