Abstract
Supporting on-demand access to large, widely shared data such as popular video objects and internet web sites requires effective use of caching at regional (proxy) servers. This caching problem is very complex because of the need to consider bandwidth as well as storage constraints at the regional servers, and because of the bandwidth sharing possibilities provided by recently proposed delivery techniques.
A linear mixed integer model is developed to configure the allocation of data objects in a hierarchical architecture containing one or more shared central servers and multiple regional servers. We will describe motivation and format of the basic model, and several enhancements to the model formulation and solution process that are necessary to solve the problem within reasonable time limits.
