Performance Evaluation for ICN over Custom-SDN Network

Information-Centric Networking (ICN) and Software-Defined Networking (SDN) are considered a promising networking paradigms in the process of developing Internet architecture. Thus The combination between ICN, which is providing efficient data distribution as a standard, and SDN by providing flexible management environment, leads to a resultant combination to be fully controllable network for efficient data dissemination. In this work, we implemented ICN functionalities by using SDN network. The network design is described based on CCNx as the implementation of ICN, Floodlight as the SDN controller type, Open VSwitch as a virtual SDN switch, and Wrapper which is a middle layer that enables the SDN open flow switch to access the ICN named data packets. Our design provides efficient content delivery with transmission delay lower than that in traditional network, and proved SDN feasibility to implement ICN with higher throughput and acceptable packet loss and jitter in comparison with traditional networks.
