摘要
研究在下一代网络中用于实现认证、授权、计费功能的AAA(Authentication,AuthorizationandAccounting)服务器所涉及的关键技术。在实现了AAA服务器的基础上讨论了AAA服务器的体系结构、前后台自适应负荷均衡机制、前台服务器中请求队列的入队和出队操作,以及在后台服务器中基于队列优先级的分时片调度机制。
The key technologies for AAA server which realizes authentication,authorization and accounting functions in the next generation network are studied.Based on an implementation case of AAA server,the following four points are focused on:the AAA server's system framework,the adaptive load balance mechanism between the front end and the back end,the enqueue and dequeue operations on the request queue within the front end,and the time slot scheduling mechanism within the back end based on the priority of queues.
