摘要
针对移动IPv6网络复杂组网形态下的高容错性需求,研究分析了移动IPv6网络多链路容错方案工作机制和容错性能,并从容错时间、服务中断时间、移动节点(MN)吞吐量、容错信令开销和引入容错方案后的移动节点注册时延五个方面探讨各方案的特点。分析和仿真结果表明:基于家乡代理(HA)与MN的联动容错方案适用于单链路和多链路,应用范围更广;基于路由更新机制的方案可以保持上层连接的连续性,部署灵活,是多链路容错的更优选择。
Aiming at the complex high fault tolerancerequirements of network in the form of mobile IPv6network, this article researches and analyzes the multilink fault -tolerance scheme work mechanism andfault -tolerant performance of mobile IPv6 network,and from the fault-tolerant time, service interruptiontime, MN throughput, fault-tolerant signaling overheadand mobile nodes registration delay in fault-tolerancescheme five aspects to discuss the characteristics ofeach scheme. Analysis and simulation results demonstrate that the scheme based on linkage of HA andMN is a better choice in multilink fault-tolerance.
