IPv6环境下的网关负载均衡策略的研究与实现

Research and Realization of a Gateway Load Balancing Strategy in the IPv6 Environment

在一个IPv6局域网中,VRRP可以在网中配置静态默认路由的环境下消除单点失效,保证了IPv6网络的稳定性。VRRP并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。本文介绍了VRRP负载均衡的组网配置。在原VRRP标准协议报文的基础上,进行报文字段扩展,提出虚拟转发器状态机的概念。通过科学的软件开发和测试流程实现,得到正确的数据,实现负载均衡策略。

On an IPv6 LAN, the advantage gained from using VRRP is a higher availability default path without requiring the configuration of dynamic routing or router discovery protocols on every end-host, and ensures the stability of the IPv6 network. VRRP does not have the ability of load balancing, the utilization of bandwidth and the optimization of resources should be improved. This article introduces the networking configuration of VRRP with load balancing. Based on the VRRP standard packet, we extend the packet field and propose the concept of virtual forwarder. With the scientific soft-ware development and testing process, we have obtained the correct data and realized the load balancing strategy.
