Enhance content broadcast efficiency in routers with integrated caching

With integrated in-network caching diagram, each router advertises the cached content to its immediate neighbors. Although the baseline content broadcast strategy can significantly improve the performance, it leads to low overall cache utilization while each router makes independent caching decisions. In this paper, we enhance the efficiency of content broadcast by providing implicit coordination among neighboring routers. Through detailed simulations, we show that the proposed technique has dramatic performance improvement over the baseline content broadcast scheme. More importantly, this performance gain can be achieved with a minimal communication overhead.
