宽带网络中负载均衡的研究

Research of Loading-balance in Broadband Network

讨论了在应用交换机上实现负载均衡的3种算法,提出了服务器负载均衡、防火墙负载均衡、Cache重定向负载均衡3种技术在大型网站中的集成应用.这种应用可以解决由于单条链路、单个服务器、单个路由器、单个防火墙或单个交换机而造成网络拥塞,形成瓶颈的问题和单点故障,提高网络性能,缩短响应时间,从而为用户提供更好的访问质量.

Traditional loadingbalance technology is used to share in loading of chains or devices by NAT technology,DNS technology,or application switch. The authors explain four kind of algorithm of loadingbalance that applied on application switch, and present a new solution that integrative apply SLB (server loadingbalance) technology,FWLB(firewall loadingbalance) technology and Web cache redirectory technology in a broadband network. The solution can solve the problem of bottleneck and singlepoint fault brought by single chain,single router,single switch or single server, improve performance of network, reduce server's response time, then provide better visiting quality for clients. 
