基于SIP协议的高可用VoIP音频通信系统设计与实现

Design and Implementation of High Availability VoIP Audio Communication System Based on SIP Protocol

为提高基于IP的语音传输(Voice over Internet Protocol,VoIP)音频通信系统的可用性,设计并实现了一款基于会话初始协议(Session Initiation Protocol,SIP)的高可用VoIP音频通信系统。首先,基于虚拟IP技术,建立系统在路由层的高可用框架。其次,在SIP协议栈层搭建SIP服务器集群,实现系统在网络音频通信业务层的高可用和负载均衡。最后,使用关系型数据库,成功搭建集群在数据一致性方面的高可用模型。实验结果表明,通过该设计可以有效降低VoIP通信系统的故障停机时间,同时可以提高系统的业务负载能力。

In order to improve the usability of Voice over Internet Protocol(VolP)audio communication system based on IP,a highly available VolP audio communication system based on Session Initiation Protocol(SIP)is designed and implemented.Firstly,based on virtual IP technology,a highly available framework of the system at the routing layer is established.Secondly,a SIP server cluster is built in the SIP protocol stack layer to achieve high availability and load balancing of the system in the network audio communication service layer.Finally,using relational database,the high availability model of cluster in data consistency is successfully built.The experimental results show that this design can effectively reduce the downtime of VolP communication system and improve the service load capacity of the system.
