摘要
IPv6以更大的地址空间、更高的安全性、更小的路由表、增强的组播支持以及对自动配置的支持等优点,将会成为未来互联网网络层的核心协议,但IPv4和IPv6将长期共存。针对此现状及NAT-PT只修改封包中网络层的消息头容易造成网络层的IP地址和SIP信息中携带的IP地址不同的局限性,分析了在IPv6网络环境下使用SIP的优势,提出了一种改进的NAT-PT进行SIP通信的解决方案。
With the advantage of more larger address,much more security, more smaller Router- table and support of multicast and auto- configuration, IPv6 will become the core protocol of network- layer in the future Internet. But the IPv4 and IPv6 will coexist for a long time. Aim at this case and the NAT- PT only modified message header of packets in network- layer which will result in the difference of IP address between network - layer and the message of SIP. Due to these shortcomings, analyzed the advantages of using SIP in IPv6 network environment, and proposed an improved NAT- PT for SIP communications.
