Abstract
Information Centric Networking (ICN) has been proposed as a new networking paradigm in which the network provides users with content instead communication channels between hosts. The Software Defined Networking (SDN) approach promises to be a solution to enable the continuous evolution of networking architectures. In this paper we propose and discuss solutions to support ICN using SDN concepts. We focus on an ICN framework called CONET, which grounds its roots in the CCN/NDN architecture. We face the problem in two complementary ways. First we discuss a general and long term solution based on SDN concepts without taking into account specific limitations of SDN standards and equipment. Then we focus on an experiment to support ICN functionality over a large scale SDN testbed based on OpenFlow, developed in the context of the OFELIA European research project. The current OFELIA testbed is…
