虚拟专用网络流量优化中的路由设计方法

摘要

本文在综述了虚拟专用网络（VPN）和相关技术后,进一步研究分析当前广域网中的常用的VPN拓扑结构及主要优缺点。设计了新的网络拓扑结构及数据包路由方法,详细介绍了设备ip设计、相关设备配置和数据包的流转举例,并总结了拓扑设计的主要优点,供用户参考。%after summarizing the virtual private network and related techniques,further research and analysis were done on the traditional virtual private network topology and it＇s main advantages and disadvantages.designed a new network topology used in WAN,describe the IP addresses and configurations of many kinds of network equipments,and also described in detail how the IP packets were flowed through these equipments.in the new designment many problems in traditional topology were solved and provided network managers with much convenience.
