Distributed WEB caching

Abstract

As an evolving area in web caching, cooperative web caching has shown promising results over centralised caching mechanisms. We introduce a novel co-operative web caching architecture called Distributed Web Caching. Distributed Web Caching introduced here, is a variant of co-operative web caching. The novel feature in Distributed Web Caching is that every client node could act as a cache server and share its cache with neighbouring nodes. A comprehensive set of protocols for access, storage and serving of distributed cached data is developed. We provide analytical models to evaluate and study of Distributed Web Caching. We implement the proposed architecture and measure the performance under different constraints.Further, we extend our analysis to object replacement strategies in Distributed WWeb Caching. We introduce simulation models to compare performance of object replacement strategies. Several novel replacement strategies for Distributed Web Caching are introduced and compared with existing stand-alone replacement strategies.
