Abstract
Recently, Content-Centric Networking (CCN) has emerged as a new networking paradigm. The main features of CCN architecture are in-network caching and content-based routing. Cache replacement and decision policies have been discussed as important mechanisms of in-network caching in past literature. However, these policies cannot efficiently support streaming. In this paper, we propose an in-network caching method for reducing playback interruption time of on-demand streaming over CCN through efficient use of network resources. The proposed method splits streaming content data into chunks with fixed size and stores these chunks into the cache storage of each CCN router in order to reduce playback interruption time for streaming. Experimental evaluations show that the proposed in-network caching method outperforms in-network caching methods of the original CCN architecture in terms of playback interruption time.
