| Summary: | 碩士 === 國立交通大學 === 資訊工程系 === 90 === Recently, with the growth of network, many applications on the network have been developed to improve the human life. One of the powerful applications is the World Wide Web system. Nowadays, many enterprises develop web applications to service clients, such as stock trading and E-commerce. Therefore, to have a high performance web server system is important. In this thesis, we design a web system based on the network infrastructure and propose an effective method called Grouping Based Dynamic Updating method to improve loading balance on web servers. In our method, we will use it to group the strongly related documents together. Then we distribute the groups among web server and keep them to handle the same number of client requests. Finally, we dynamically update dispatch table, and sustain the loading balance on web servers constantly. According to the performance evaluations, our method is superior to other schemes in response time and loading balance status. Besides, our method also can offer a better QoS no matter in small-scale or large-scale web system. The detail design concept and performance evaluations will be described in the literature.
