Modelling and Performance Analysis of Cache Networks.

This paper develops and implements a World Wide Web cache infrastructure model which is to be used for analysis of features that are otherwise difficult to get from existing log data or for evaluation of nonexisting cache scenarios. A prominent feature of our model that differentiates it from other similar models is its dynamical aspect, which allows for the investigation of temporal features. Using the model we verify and quantify observations made from real log data and provide a more comprehensive picture of the caching processes that take place behind the scenes. We also show how the model can be used to assess the economic viability of the caching solution
