| 摘 要： | 在移动IP协议中，为了减少切换过程中的丢包率引入了平滑切换机制，但该机制只能恢复部分丢失的分组。当切换过程中有连续的3个以上分组被丢失，并且有2个以上通过平滑切换机制得以恢复时就会因触发TCP层的错误快速重传导致网络吞吐率下降。本文对该问题进行分析并提出了解决的方法。

| Abstract: | Smooth handoff is presented to reduce packets lost in mobile IP, but it only recover packets partly. More than three packets are dropped consecutively during a handoff and more than two packets are recovered by using smooth handoff, an erroneous fast retransmit occurs and the throughput of network is reduced. A method to resolve this problem is presented. |
