Unveiling the Content-Centric Features of TCP

—Content-centric networking has been proposed as a new networking paradigm that is centered around the distribution of content. A key idea of content-centric networks is to address content by name and to enable nodes in the network to respond to content requests. Most proposals for content-centric networks require a ”clean slate” approach and a replacement of today’s TCP/IP protocol stack, which raises questions about a feasible deployment path. In this paper, we ask the question to which extent the ideas of content-centric networks can be realized on top of today’s IP protocol suite. We explore an approach for name-based addressing that extends today’s TCP/IP protocols in a fully standard compliant way. We implement our new method in order to demonstrate its feasibility and evaluate the performance of the system using both latency and processing overhead as measures. The obtained results demonstrate that name-based addressing on TCP/IP is feasible. We also acknowledge that...
