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.
