Abstract: AAA server supporting radius protocol is widely applied in telecommunication industry. In this paper, a memory cache technology is introduced, which can promote AAA server's performance with 2~3 order of magnitude.With Unix system V shared memory technology, semaphore synchronizing competitively occupies resources among multiple processes, hash table implements fast search in massive data.

摘要： 支持Radius协议的AAA服务器在电信行业得到广泛应用，该文介绍了一种高速缓存技术，将AAA服务器的性能提高了2~3个数量级。该技术利用Unix提供的共享内存机制，用信号量同步多个进程对资源的竞争使用，Hash表实现海量数据的快速检索。
