SIP服务器系统

摘要

With the development and improvement of Session Initiation Protocol (SIP), servers based on SIP have been widely applied in Communication Systems. However, the performance of single SIP server to handle SIP messages is limited on the condition of the hardware does not upgrade. The performance won’t meet the demand of large-scale increasing of the number of users. Through of research and analysis on SIP, the paper designed and implemented SIP Server Clusters. By using multiple servers working together, more requests can be dealt with concurrently, which is an improvement of performance. The design is simple to implement and has high scalability. These clusters Practice has proved that the proposed solution can adequately address the current shortage, providing supports for future services expansion.%随着会话初始协议SIP(Session Initiation Protocol)的完善和发展，基于SIP协议的服务器广泛应用于通信系统中。然而在硬件不变的前提下，单一 SIP 服务器的负载能力有限，无法满足大规模用户数量的增长。本文在充分研究和分析SIP协议的基础上，设计实现了一个SIP服务器系统。该系统中，使用多个服务器实例协调工作，并发的增加了处理请求的数量，从而提升对 SIP 服务的处理能力。该设计具有易于实现和扩展性强的特点。实践证明，本文设计的方案能够解决当前的不足，为未来的业务的扩展提供了支撑。
