Analytical performance prediction of WWW distributed cache management (DCM) protocols

We introduce analytical models for predicting the performance of World Wide Web (WWW) proxy caches that are distributed over multiple proxy machines under various management protocol assumptions. The purpose of these models is to determine which distributed cache management (DCM) protocols are to be used for large-scale distributed caches. The accuracy and usefulness of our models is assessed by comparing the performance predicted by the models with measurements from real system in operation. We run tests with different values of various parameters that define behavior of distributed cache, communication protocol, DCM protocol, and application.
