摘要
移动IP是支持IP移动性的协议,但是当其用于移动节点驻留在远离归属网络的外地网络时,将会产生严重的注册延迟,从而引起严重的包丢失和通信吞吐量的下降,为了改变这些不足,人们把移动节点的移动方式分为宏移动和微移动,并且提出了很多应用于微移动的移动性管理方案。文章深入研究了宏移动协议(RFC2002)和微移动协议的包丢失率,给出了计算公式,并且对计算结果进行了详细的分析。
Mobile IP is the proposed standard for IP mobility support.When a mobile node is far away from home ,reg-istration at its home agent can cause a long handoff delay that leads to significant packet drop and throughput reduc-tion.In order to prove standard Mobile IP,mobility of MN has been divided into Micro-mobility and Macro-mobility.Some micro -mobility management proposals has been developed.It has compared of packet loss probability between macro-mobility protocol(RFC2002)and micro-mobility management protocols,and has given some equations along with analysis of calculating results.
