A.: A similarity based approach for integrated web caching and content replication in cdns

Web caching and content replication techniques emerged to solve performance problems related to the Web. We pro-pose a generic non-parametric heuristic method that inte-grates both techniques under a CDN. We provide experi-mentation showing that our method outperforms the so far separate implementations of Web caching and content repli-cation. Moreover, we show that the performance improve-ment compared with an existing algorithm is significant. We test all these techniques in a simulation environment un-der a flash crowd event and a workload of a typical light-weighted CDN operation. 1
