WDC: A WEB CACHE ARCHITECTURE BASED ON LOCAL CONTROL

摘要

This paper introduces a new system of Web Cache. Based on the local characteristic of the Web access, we establish a Web Cache Architecture with a centralized control layer. In the control layer, we implemented the load balance method, prefetch method based on the pull mechanism, and the eliminate method based on the conjunction of TTL and the live modulus. Using these methods, the control layer can control the whole Web Cache layer efficiently based on the access content and access flux. This high performance architecture can improve the hit rate, and shorten the response time in local area.
