Cooperation Policies for Efficient In-Network Caching

Caching is a key component of information-centric network-ing, but most of the work in the area focuses on simple en-route caching with limited cooperation between the caches. In this paper we model cache cooperation under a game the-oretical framework and show how cache cooperation policy can allow the system to converge to a Pareto optimal con-figuration. Our work shows how cooperation impacts net-work caching performance and how it takes advantage of the structural properties of the underlying network. 1
