Dynamic Web caching: For robustness, low latency & disconnection handling

The Distributed Web caching system provides fast retrievals of web pages but still limited by the delays incurred by servers. As these systems are affected by low robustness due to highly congested servers. As in real time, servers get disconnected frequently providing tradeoff to service. Robust Distributed Web Caching (RDWC) handles robustness but fails to deal with the frequent disconnections. So in this paper, we discussed effective Distributed Web Caching (DWC), Distributed Web Caching with Clustering (DWCC) and Robust Distributed Web Caching techniques. Then a scheme is proposed and designed which can overcome frequent disconnections of proxy servers & more delays incurred in these schemes, it can send the replies back to clients in lesser time (by factor n- Best Case). Clustering of Proxy Servers is used with dynamic allocation of requests to less congested servers to achieve load balancing and robustness. Then a comparison of our Scheme is done with these and results are given in comparative table.
