摘要
文中在基于Linux操作系统的VoIP网关中 ,以单链路SIP信令实现为基础 ,提出了采用多进程架构的多链路SIP信令模块的设计实现方案。该设计继承了SIP协议固有的简单 ,可扩展性强等优点 ,而且多进程架构的设计结构清晰 ,能同时支持多路VoIP会话的建立与维护 ,解决了多用户的VoIP服务接入问题。该方案目前已用于基于Linux平台的VoIP网关的信令实现 。
This paper presents the implementation of multi session SIP signal module in VoIP gateway based on current SIP implementation under Linux platform. This solution inherits the advantage of SIP protocol simple, extensibility and etc. The usage of multiple process mechanism in software architecture design supplies the ability of supporting multiple VoIP sessions simultaneously and solve the problem of multiple user access to VoIP service. This solution is already adopted in the VoIP gateway signal module under Linux platform and meets the requirement of multi session maintenance well.
