Hybrid Web Caching Framework for Reduction of Web Latency

Abstract

Distributed web caching and Hierarchical web caching are two important techniques to minimize the problem of web latency. Web latency is the time taken by user in retrieving the web documents. The main performance problems with distributed caching are longer connection times and overhead such as resolution delay, queuing delay etc in used bandwidth. Whereas the main issue with Hierarchical caching is longer transmission times. So there is a need of a sophisticated combination of a hybrid scheme to effectively reduce web latency. Studies show that combination of Hierarchical and Distributed web caching reduces transmission time and connection time thereby reducing the overall latency time. Our results show that we can improve hit ratio from Hierarchical and Distributed caching strategy by 55% and 42% respectively.
