The Resource Efficient Forwarding in the Content Centric Network

Today's networking technologies in Internet that can only speak of connections between hosts no longer adapt to the network increasingly dominated by content distribution and retrieval. Some efforts therefore have been made to generalize the Internet architecture by taking content as a primitive- decoupling location in the network instead of focusing on endpoint addresses of hosts. However, one of the representative architectures known as Content-Centric Networking (CCN) consumes excessive system resource in terms of router's processing capability, the buffer space in the router and the network bandwidth when deployed as the "universal overlay" in the existing network. We present the solution composed of two methods to improve the resource efficiency based on the CCN approach. The results from the ns2-based simulation disclose that our solution can reduce the resource consumption in routers and network pipeline significantly in the overlay architecture.
