摘要： 提出了一种基于内容的Web集群服务器负载均衡算法,该算法通过引入一个衡量不同内容任务量并利用当前真实节点上的连接数和请求内容的任务量以及真实节点的处理能力来调整服务器负载。同时,算法引入了一个反馈环节,将真实节点的负载信息反馈到负载均衡器,让负载均衡器调整自己的负载均衡策略,提高它的自适应能力。

Abstract: This paper presents a content-based load-balancing algorithm, and studies on the following two questions. First, the nodes load by thre variables, the node weight, connection numbers and the requested contents length are measured. Second, a feedback is brought in, to balance the load mor optimization . The weight of each node interval is adjusted according to the real load of each node.
