| 摘 要： | 集群技术为Web服务带来了新的解决方案,其核心思想是负载均衡策略.在分析已有方法的基础上,提出了一种基于内容分类的集群负载均衡算法.该算法通过对用户请求分类后均匀地分配给各节点服务器,以使每个节点服务器得到的各类请求量大致相同.同时算法引入了一个反馈环节,通过负载权值的等效变换和进入临界状态后的动态权值调整来防止节点负...

| Abstract: | The cluster technology brings a new solution for the WEB service,the key point is load balancing strategy.Based on the existing algorithms,a content-classification load balancing algorithm is proposed.By using content classification,user requests could evenly distribute to the nodes in the cluster,so that each node would get roughly the same amount of various types of requests.To prevent the load skew,a feedback mechanism was introduced,furthermore,the weight of each node interval was adjusted by using an e... |
