| 摘 要： | 虚拟路由器冗余协议(VRRP)是在局域网中配置静态默认路由的环境下消除单点失效的一种容错协议。VRRP不支持动态负载均衡,对带宽的利用和资源的优化都有待提高。本文在VRRP工作原理的基础上提出了一种增强VRRP,通过每个路由器定期交流信息来确定主备状态;主路由器负责虚MAC的分发和根据负载均衡算法回应ARP/ND请求,来实现流量的动态负载分担。设计实现的EVRRP能够与当前标准VRRP兼容。

| Abstract: | Virtual Router Redundancy Protocol (VRRP) is designed to eliminate the single point failures in the static default routing environment of LANs. The original VRRP protocol does not support dynamic load balancing,and the bandwidth use and optimization of resources are yet to be improved. This paper proposes EVRRP,which is called enhanced VRRP,based on the principle of VRRP. Each router periodically exchanges information to determine the status of the master and backups. The master router distributes the virtu... |
