摘要
介绍了软交换的技术特点和技术目标,给出了软交换的网络结构,并对软交换的网络结构工作原理进行了说明。从设备配置、服务质量(QoS)、异地容灾、SIP协议的网络地址转换(NAT)穿越、安全问题等方面分析了软交换组网时需要关注的技术要点,提出了相应的组网技术要求。
The soft-switching’s technical features and objectives are introduced,and the network architecture and its working principles are also proposed in this paper.Technical issues of soft-switching network is analyzed,including device configuration,QoS,disaster recovery,NAT traversal of SIP protocol,security etc.Finally,the technical requirements for constructing network are presented.
