Deploying proxy servers on locations geographically close to the users can significantly reduce response time and network traffic. Proxy servers usually cache recently or frequently requested web objects temporarily in the hope of satisfying future client requests without repeatedly connecting to servers containing them. In reference [2], event-driven simulations were performed to evaluate the variable-sized, distance-sensitive segment approach to proxy caching of large media objects. The performance of the segment-based proxy caching was also compared with a whole media approach and a prefix/suffix approach. In this paper, we study more complex systems comprised of a proxy server and a few media servers following the same data migration protocol as proposed by Baker and Moon [3] for Distributed Cooperative Web Servers (DCWS). We vary the number of the media servers in the system and conduct event-driven simulations on them, comparisons are made on the performance achieved by systems with different number of servers. Our simulation results reveal that the network performance improves significantly when the caching of media files is segment-based and segments are allowed to migrate among the content servers.
