They reported a substantial reduction in community work load that can be obtained from this proxy sharing. This shared cache also lead to a corresponding increase in performance. Instead of cache sharing, Law and Nandy investigated a distributed proxy server structure that may enhance the service availability, provide system scalability, coupled with load balancing functionality. The system employs TCP-primarily based switching mechanism which has a finer session granularity, and extra dynamic management on resource allocation. Finally, researched the power of proxy servers to cache video.
