Abstract

The goal of Content Centric Network (CCN) is to provide high-efficient mechanism to store the content which is widely stored at the network center and edge. Content name, rather than IP, is used for data transmission in CCN. It is necessary to identify content, and keep the mapping relation between content and network interfaces. With the data exponential growth, scalability in CCN will be more serious than TCP/IP. In this paper we present a Distributed Hierarchical Rrouting for Content Centric Network (DHR-CCN). This model provides the efficient information diffusion of the content name to reduce the overhead of naming routing. Moreover, this mechanism provides novel content management and organization to raise transfer speed. We define content entropy to quantify the CCN routing uncertainty. Finally, the performance of DHR-CCN has been evaluated.

Keywords: content centric network, name routing, hierarchical routing, scalability.
