摘要
负载均衡作为一种策略,能够让多台服务器或多条链路共同承担繁重的计算或大吞吐量工作,从而以较低成本消除网络瓶颈,提高网络的灵活性和可靠性.针对C/S模式的不同层次,网络负载均衡有四种实现方式.介绍了LINUX系统下集群负载均衡技术三种工作模式的工作原理、优缺点,同时以VS/NAT模式为例介绍了LINUX集群负载均衡的配置.
As a kind of tactics to eliminate network bottle-neck,load balancer enables many servers and link-layers to undertake heavy tasks together, which improves the reliability and flexibility of the network. The network load balancer has four realization models at different C/S layers. The work principle of three load balancer models on LINUX system are introduced,and how to config LINUX load balancer by the example of VS/NAT models is also introduced.
