| 摘 要： | 在分析MRSVP(Resource Resercation Protocol with Mobile Hosts)协议的基础上,针对MRSVP协议在处理单播流时的缺陷,提出了最大QoS(Quaity of Service)共享路径的概念,给出了计算最大QoS共享路径的算法并对MRSVP协议进行了改进.分析结果表明,改进后的MRSVP协议相对改进前,在网络重载情况下,缩短了重新进行资源预留的路径,从而提高了资源预留成功率,增加了移动主机在子网间切换的成功率,缩短了移动主机切换的时间.

| Abstract: | On the basis of analyzing the protocol of MRSVP(Resource Resercation Protocol with Mobile Hosts), a new concept of the maximum QoS sharing path is proposed aiming at the limitation of the MRSVP protocol when dealing with unicast flows. An algorithm is provided and a modified protocol of MRSVP is proposed. By analysis it be found out that in contrast to MRSVP, the modified version of MRSVP increases the probability of mobile hosts' successful resource reservation when network is heavy loaded.It increases the probability of mobile hosts' successful handoff between subnets and also cut the time of mobile hosts' handoff and provides better QoS guarantee under the mobile circumstances. |
