Research on Web QoS Mechanism for Web Server Cluster System
Cai Wan · 2004
Web QoS is a critical research of current Web computing,and it is a solution to end-to-end QoS assurance in Web computing environment.In this paper,a QoS-supporting Web server cluster system scheme and realization technique is presented.The whole system consists of two levels:the QoS-supporting cluster switch and Web server cluster.Here,through the cooperation of cluster switch and Web servers ,the distributed QoS assurance system,which combines priority-switching and priority-serving,is built,and accordingly meets the users requirements for services quality.By system testing,the performance of the prototype system can reach the design requirements.
