摘　　要：随着电子商务的应用逐步深入,用户访问量的激增且服务请求多样.如何实现对所有请求的快速响应是当前解决的问题.针对此问题,本文提出采用基于区分Web QoS的负载均衡技术.建立了基于区分Web QoS的负载均衡的集群模型.根据请求类型和用户权限划分服务等级,高服务的请求具有高优先调度权,在集群当中通过动态反馈技术均衡调度到某个节点,从而达到区分Web QoS服务的目的,同时也保证集群服务器的负载均衡.该模型在网络环境及硬件环境相同的条件下,与常用的负载均衡技术进行了比较,实验结果证明本文提出的方法效果显著.With the gradual deepening of e-commerce applications, the user accesses are sharply increased and the service requests become more diverse. How to achieve quick response to all requests is the current problem. To solve this problem, this paper proposes a Web QoS distinction based load balancing technology. Establish Web QoS distinction based load balancing cluster model. According to the type of service request and the service level for the division of user authority, high level service requests with high priority scheduling rights, which in the cluster are scheduled to a node by dynamically balancing scheduling feedback technology, so as to achieve the purpose of distinction of the Web QoS services, meanwhile, also to ensure the load balance for the cluster server. Under the same network and hardware environment conditions, this load balancing cluster model has been tested and compared with some commonly-used load balancing technologies, the experimental results proved that the proposed method was much more effective.
