Web Quality of Service:A Survey
Shan Zhi · Chinese Journal of Computers · 2004
With the evolvement of the E commerce, the Internet is undergoing substantial changes from a communication and browsing infrastructure to a medium for conducting business and selling services. These changes place the Web server at the center of the E commerce infrastructure with increasing requirements for providing service differentiation and performance assurance. To that end, Web servers must have mechanisms and policies for establishing and supporting QoS. A summary of the Web QoS technologies considered in the literatures is presented, including the methods of request classification, the Web QoS supporting mechanisms provided by the Web server software, the operating system, and the middleware, and the QoS control mechanisms and policies in the Web server clusters. Research directions and open problems in this area are also discussed.
