Modeling Web caching schemes for performance studies

This paper outlines a generic approach to modeling Web caching schemes. Four Web caching schemes-SH, ICP, CD, and CNP-were modeled to study their performance in terms of request latencies. There were two important findings. First, conventional Web caching schemes such as SH, ICP, and CD would have shorter request latencies if total numbers of levels in their caching hierarchies were one or two. Second, under some reasonable assumptions, CNP was found to outperform the other schemes in terms of request latencies.
