【摘要】 移动IPv6中引入路由优化的目的是缩短移动节点与通信节点之间的端到端延时。为了观察路由优化对网络性能产生的影响,采用NS-2网络模拟软件创建了较为复杂的移动IPv6网络环境,通过切换延时、分组丢失、端到端延时等典型的移动IPv6网络性能参数影响实验,经过对仿真结果的分析,提出了一个切换延时和分组丢失的计算公式,并指出,路由优化可能会导致增加切换延时和分组丢失。给出了一种对移动IPv6网络性能影响极小的路由优化策略。结果表明,基于路由优化对移动IPv6网络性能是有影响的。更多还原

【Abstract】 The aim of route optimization in Mobile IPv6 is to shorten the end-toend delay between the mobile node and the correspondent node,but the impact of route optimization on the network performance is still unclear.The NS-2,a network simulation software,was used to create a fairly complicated Mobile IPv6 network environment for observing the impact of the route optimization on some typical Mobile IPv6 network performance parameters,such as handoff latency,packet loss and end-to-end delay.By analyzing the simulation results,an advanced formulas of handoff latency and packet loss was put forward,and the results showed that the route optimization may increase the handoff latency and packet loss.更多还原
