Abstract: It is beneficial to implement communications based on SIP in the heterogeneous network without changing application programs on client hosts. This is the main content of this paper. After analyzing SIP messages and several common mechanisms of translating between IPv4 and IPv6, this paper offers a solution based on the cooperation of SIP_ALG and NAT-PT.

摘要： 讨论了如何在不改动终端的情况下,实现异类网之间的SIP通信。在分析SIP消息包和常见的IPv4/IPv6转换机制的基础上,描述了一种应用层网关与NAPT-PT相结合的解决方案及其实现。
