Abstract

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 virtual MAC answers the ARP/ND requests on the basis of the load balancing algorithms, and achieves the dynamic loadsharing of traffic. EVRRP is designed and achieved, which is compatible with the current standard VRRP.
