摘要
随着上网用户的激增,电信级的Radius应用服务器的性能问题越来越受到关注,研究一种软件实现的稳定、高效多进程通讯的同步机制,解决可靠提升接入认证服务器整体性能的问题,现实中采用了共享内存结合可靠信号量和原子变量技术,实现共享内存锁机制,应用于Radius服务中,深入细致剖析共享内存锁机制是如何避免访问冲突的,提供了新的思路。在实践中满足了百万级用户的认证授权要求,在服务端性能调优方面起着重要的作用。
With ChinaNet users increasing drastically, the performance of telecom RADIUS is more and more concerned with. An efficient multi-processing synchronous mechanism is studied in order to increase the capability of authentication server by combining share memory and reliable signal as well as atomic variables to realize share memory lock mechanism. A new way for avoiding accessing conflicting is offered by using share memory lock mechanism, which satisfies the requirements of authentication and authorization of the users, and hence plays an important role in optimizing the performance of the server.
