Abstract
Informationcentric networks ICNs replace IP addresses with content names at the thin waist of the Internet hourglass thereby enabling pervasive routerlevel caching at the network layer In this paper we revisit pervasive content caching and propose an algorithm for cache replacement at ICN routers by incorporating principles from network coding a technique used to achieve maximum flow rates in multicast By introducing a low computational cost in the system networkcoded caching better utilizes the available small storage space at the routers to cache more effectively in the network Results of our experiments on the global enterprise for network innovations GENI testbed demonstrating the performance of our algorithm on a real network are included in the paper We evaluate the algorithm in two different traffic scenarios i videoondemand VoD ii Zipfbased web traffic Working with the named data networking implementation of ICN we also present the additional headers and logical components that are needed to enable networkcoded caching In a nutshell we show that an integrated codingandcaching strategy can provide significant gains in latency and content delivery rate for a small computational overhead
