Priority Access Mechanism for Improving Responsiveness to Users through Cache Server

This research aims at caching non-interactive dynamic contents such as news and weather, and blogs when users only read them. We think that there is no problem for users even if they browse these dynamic contents in several seconds later. Quick update cache is required to achieve practical use of caching dynamic contents. We developed Priority Access Mechanism which adjusts the quota of the computer resource to handle access from cache servers. By this mechanism it can response to cache servers quickly even if there is huge amount of other requests from clients which accesses to Web server directly. This paper describes design, implementation and evaluation of Priority Access Mechanism. From results of experiments, we confirm that it is possible to adjust the quota of the computer resources to process accesses from cache servers, and cache server can update contents in a short time and response to users quickly.
