摘　　要：针对多个移动节点(MN)同时切换场景下切换过程受其他节点影响较大的问题,提出了代理移动IP协议中利用有限状态吸收马尔可夫链分析多个MN同时切换场景的模型,推导了多个MN切换时完成链路层切换的总时延公式;给定时延限制下MN切换成功的概率和移动接入网关的容量公式.仿真结果验证了建模分析的正确性,与已有研究结果对比表明,所提建模方法更合理,所得结论可作为网络管理和配置的参考.When multi-mobile nodes(MN)simultaneously initiate handoff,the handoff process of a MN will greatly influenced by other nodes.Finite-state absorbing Markov chain is adopted to model the process of multi-MN’s handoff in proxy MIPv6 and the total handoff delay of multiple MN is derived.Besides,the handoff success probability and the capacity of mobile access gateway under delay limitation are deduced.Moreover,we validate our modeling by simulating the handoff process and comparing with the existing work.The results could be a reference for network administration and configuration.
