摘要
传统防火墙是在单点将内网接入外网,它会因单点失效而成为网络的瓶颈,降低网络的可用性。防火墙集群能够提高防火墙的高可用性。文章阐述了防火墙集群的必要性和方式,提出了负载均衡算法的设计思路和方法,以及防火墙集群系统的容错方法。
Traditional firewall connects external network and internal network in single entrance point.Single-point-failure for firewall gradually becomes the network bottleneck, debases the network＇s availability .The firewall cluster technology can enhance firewall＇s high availability.This paper illuminates the importance and mode of firewall cluster system firstly,and puts forward idea and method of load balancing algorithm ,and provides fault tolerance method for firewall cluster system.
