H2N4: Packet forwarding on hierarchical hash-based names for content centric networks

In this paper, we propose a novel solution to scalable forwarding problem in content centric networks (CCN) that relies on the use of hash-based content names for packet forwarding. Proposed approach continues the hierarchical naming format of CCN by converting human readable name prefixes to their hashbased counterparts to enable faster packet processing at the content routers, with additional proposed modifications at the edges to support hash-based forwarding. We present an in-depth study of the proposed architecture using numerical analysis that rely on actual datasets and realistic performance measures. Our results suggest significant improvements in storage requirements and processing overhead with the proposed architecture to support higher line rates and more efficient resource usage in the network.
