摘要：These days web caching suffers from many problems like scalability, robustness, metadata management etc. These problems degrade the performance of the network and can also create frustrating situations for the clients. This paper discusses several web caching schemes such as Distributed Web Caching (DWC), Distributed Web Caching with Clustering (DWCC), Robust Distributed Web Caching (RDWC), Distributed Web Caching for Robustness, Low latency & Disconnection Handling (DWCRLD). Clustering improves the retrieval latency and also helps to provide load balancing in distributed environment. But this cannot ensure the scalability issues, easy handling of frequent disconnections of proxy servers and metadata management issues in the network. This paper presents a strategy that enhances the clustering scheme to provide scalability even if size of the cluster grows, easy handling of frequent disconnections of proxy servers and a structure for proper management of cluster's metadata. Then a comparative table is given that shows its comparison with these schemes.
