摘　　要：身份与位置分离机制很好地解决了核心网的路由可扩展问题,成为当前互联网领域研究的热点之一。为了更好地改善互联网对移动性的支持能力,各种域内微移动协议也成为各大高校和通信业公司的重点研究方向之一。在分离与映射机制下,提出了虚拟树状子网网络结构,设计了接入子网的路由以及终端的接入过程,实现了微移动协议。接入子网的引入使得终端的移动不再是必须经过核心网的宏移动,有效地降低了终端移动切换过程中的时延和丢包率问题。Presents a new fixed subnet accessing based on identifier to locator mapping mechanism,which has already become a hot research topic in the current Internet research area.For improving supporting mobility of Internet,micro-mobility protocol becomes one of main research direction for high schools and telecommunication companies.Proposes the hypothesized tree subnet network architecture,designs the process of terminal accessing as well as subnet routeing,and realizes the micro-mobility protocol based on identifier to locator mapping mechanism.The introduction of sub-network access makes the mobility of terminal is no longer a macro-mobility which must pass through the core network,effectively reduces the handoff delay and packet loss rates in the process of terminal mobility.
