- The in-network caching strategy in named data networking can not only reduce the unnecessaryfetching of content from the original content server deep in the core network and improve the user responsetime, but also ease the trafc in the core network. However, challenges exist in in-network caching, suchas the distributed locations of storage and relatively small cache space which limit the hit rate, and thecache management introduces further overhead. In this paper, we propose a two-layer hierarchical clusterbasedcaching solution to improve in-network caching efciency. A network is grouped into several clusters,then, a clusterhead is nominated for each cluster to make caching decision. The clustering approach offersscalability and permits multiple aspects of inputs to be used for decision making. Our solution jointlyconsiders the location and content popularity for caching.We implement our strategy in ndnSIM and test it onGEANT-based network and AS3967 network. Our simulation results show signicant improvement over itspeers.INDEX
