移动计算机网络协议结构

PROTOCOL ARCHITECTURE OF MOBILE COMPUTER NETWORK

本文研究了移动计算机网的动态寻址和移动透明性问题，提出了基于归属名字服务器和拜访名字服务器的移动管理方案．归属名字服务器存有移动台的归属地址和当前地址等信息．拜访名字服务器存有进入其所在子网移动台的寻址信息，并在移动台离开后延缓两倍分组寿命的时间再删除其寻址信息，既避免频繁地交互移动管理信息，又不用担心寻址信息过时．本文给出了移动计算机网络的协议结构，可支持有连接和无连接通信．

This paper studies the dynamic addressing and mobile transparencyproblems of mobile computer network, gives out an approach for mobility management based on home name servers and visiting name servers. The home address andcurrent address of a mobile station are stored in its home name server. And the address information of a mobile station entering a subnetwork is stored in thesubnetwork's visiting name server, such information will be deleted when the mobile station have been away from the subnetwork for twice packet lifetime, thusavoiding frequent mobile management information communication without such address information being obsolete. The protocol architecture of mobile computer network is given, which can support connection oriented and connectionless communications.
