摘要
IPV6的出现不但解决了地址空间紧缺问题,对网络性能的改善也有卓越表现,但是IP地址同时用作用户的身份标识和位置标识,语义过载,不能很好地解决主机移动性和安全性方面存在的问题,应提出一种新的机制加以克服;基于终端的身份与位置分离的设计思想,文中把HIP和SIP协议应用到新的一体化网络中,提出一种基于标识的移动通信机制。
IPV6 not only provides a new method to settle the scarcity of the IP addresses, but also improves the net performance. However, IP address is overloaded in semantics because it is used to represent both the location and the identity of a user, and it is impossible to solve the serious problems of the mobility and safety on current Internet. Thus a new mechanism should be proposed. According to the thought of the namespace improvement solutions that separate from each other the identity and the position of a user, this paper puts forward a mobile communication mechanism based on identity, and applies HIP ＆ SIP protocols to the universal network.
