CRoS-NDN: Controller-based Routing Strategy for Named Data Networking

Named Data Networking focuses on the communicated data name, fundamentally changing the network task of locating and forwarding information. Additionally, the huge amount of content names challenges the scalability of techniques used for this task. This article proposes a strategy that consolidates the control plane on a dedicated node apart of switches responsible for the data plane. The proposal shows higher performance compared with others strategies identified in the literature. The comparison uses analytical modeling and simulation to measure convergence delay and efficiency in terms of useful and signaling traffic ratio. The results demonstrate the proposal superior performance with up to 75 % better signaling efficiency and more than 1000 seconds faster convergence time in an ISP simulated topology.
