Performance Comparison and Optimization of ICN Prototypes

Information Centric Networking paradigm is a solid proposal to update the original Internet design. While the research community is still working on technical improvement, the technology has reached a stage that allows the design, testing and deployment of ICN specific applications. To this goal, the development of testbeds allowing researchers to evaluate their applications in a real setup is of key importance. There are few existing ICN prototypes that would allow experimenters to work in this direction. Their performance is fundamental, so that they do not create artificial bottlenecks affecting test reliability. Unfortunately, existing solutions have been designed to demonstrate the feasibility of the ICN solution, thus lacking of optimization and scalability required to run reliable scalability tests. In this paper we address this problem by first, offering a performance comparison between available ICN prototypes and, second by proposing a revisited system design, CCN-par, to increase scalability, and remove bottlenecks that hamper current software-based testbeds.
