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.
