摘　　要：路由优化是移动通信领域的一个重要研究课题,标准移动IP协议的不对称的三角路由给通信造成时延过长、网络资源浪费问题。讨论了一种由家乡代理发出绑定更新消息信令的路由优化方案,并通过NS仿真比较了路由优化前后数据包传输路径。仿真结果表明,路由优化方案消除了三角路由的影响,很大程度上提高了网络的传输效率。Route optimization has been an important research topic in mobile communication. In the basic mobile IP protocol, asymmetric triangle muting causes large delay and network resource wasting. Route optimization technique extends the basic mobile IP protocol and adds binding update messages to improve network performance. NS simulation has been implemented to compare transmission routes of the packets, indicating that the route optimization mechanism eliminates the effect of ＂Triangle Routing＂ and improves network efficiency.
