A model for monitoring and migrating Web resources Available to Purchase

Web resource usage statistics enable server owners to monitor how their users use their Web sites. However, such statistics are only compiled for individual servers. If resource usage was monitored across the whole Web, the changing interests of society would be revealed, and deep insights made into the changing nature of the Web. However, capturing the information required for such a service, and providing acceptable system performance, presents significant challenges. As such, we have developed a model, called WebRUM, which offers a scalable system‐wide solution through the extension of a resource migration mechanism that we have previously designed. The paper describes the mechanism, and shows how it can be extended to monitor Web‐wide resource usage. The information stored by the model is defined, and the performance of a prototype mechanism is presented to demonstrate the effectiveness of the design.
