一种微移动环境中高效RSVP路径管理方案

Efficient RSVP Path Management Scheme for Micro Mobility

在微移动/无线环境下,针对延迟抖动敏感的实时业务,高效RSVP路径管理方案通过分步地顺序执行指针转发RSVP路径扩展方法和交叉路由器RSVP路径部分建立方法,设计了一种高效的微移动资源预留协议MMRSVP,同时兼顾了移动主机RSVP切换的延迟时间和网络资源利用率.性能分析与仿真实验表明,在RSVP切换延迟和资源利用率上,MMRSVP均取得了优越的性能.

In micro mobility/wireless network environment, the RSVP with Pointer Forwarding method and RSVP with crossover router method are sequentially utilized by the efficient RSVP path management scheme for micro mobility. Subsequently, an efficient Resource reSerVation Protocol for Micro Mobility （MMRSVP） is designed on the basis of the scheme. The handoff latency of RSVP and the usage of network are impartially taken into account by MMRSVP. It is both shown by simulation results and performance analysis that the handoff latency of RSVP and the usage of network of MMRSVP are simultaneously improved.
