基于协同机制的Web服务器集群负载均衡技术

Load balance technology of web server cluster based on cooperative work mechanism

网站为了满足因特网的大量访问以及更好的QoS保障,目前通用的方案是多台Web服务器构成一个集群,共同分担用户对站点的请求负荷,这就需要解决负荷在各服务器之间的平衡(即负载均衡)问题。简要分析当前常用的Web服务器集群负载均衡方案,提出了以在线量为负载参考点,同时兼顾不同性能Web服务器的负载能力,建立一种集群服务器之间的协同工作机制,以实现Web服务器的负载均衡。

In order to satisfy a great deal ofinternet interview and the better QoS guarantees, the general project will set up a web server cluster to share the customers＇ request to the website together, which need to resolve the problems of the burden equilibrium among the servers （namely load balance）. The common load balance project of web server is analyzed, taking on-line number as the reference of server＇s load, taking into account the load ability of the different function web servers at the same time, a kind of cooperative work mechanism among the servers is built to fulfill the balance of web server cluster.
