Towards scalable agent based web service systems

The increasing development of the Internet requires highly scalable, available, and reliable web servers in order to provide rapid response and high throughput to requests from hundreds millions users occurring at any time. The disadvantage of old fashioned approach which uses single-alone web servers is the problem of bottle-neck and overload on the server side as well as many additional problems for the network such as network traffic and routing overload. The load balancing problem of web servers can be solved with replicated web servers. However, the problems on the network are still left out. In this paper, we propose a framework to reallocate jobs from web servers to proxy servers that are close to the clients. By delivering certain jobs from requested web servers to designated proxy servers with mobile agents and executing these jobs at the proxy servers, our approach can reduce the load for web servers as well as reduce the traffic for the overall network.
