Reducing Read Overhead in CCN Routers via Aggregating Interest Packets

Article Preview

Abstract:

Content-Centric Networking (CCN) is proposed to make content, instead of the content locations, as the first-class entity in future Internet. Content can be cached in CCN routers for better data delivery, which makes in-router caching system more important. Content Store (CS) is the CCN in-router cache that caches all the data packets traversing a CCN router. Nowadays the throughput of IP routers can reach up to hundreds or even thousands of Gbps, which makes it a great challenge to design CS architecture in CCN routers to support high read/write throughput. In this paper, via aggregating the interest packets that request for the same data packets, we propose an aggregation scheme system, which can help to reduce the read overhead of the CS in CCN routers.
