—Recently the Software-Defined Networking (SDN)
has attracted increasing attention in the research community
around the world. In this paper, we focus on how to modify the
OpenFlow protocol, the most popular SDN instantiation, and
use SDN functions to enable Information-Centric Networking
(ICN). We describe the design based on CCNx (a virtual
experiment network based on the concept of ICN), Floodlight (a
kind of SDN controller) and a revised Open Vswitch (a virtual
switch in SDN). We build a testbed that i) allows to identify the
content requests, ii) realizes the routing process of ICN in SDN,
iii) enables efficient content delivery, iv) is able to be deployed in
existing IP networks. In addition, the proposed paradigm
continues to support traditional host-to-host communication
using TCP/IP. We will present how Open Vswitch should be
altered to better match the Operations of CCNx and how CCNx
can be implemented over the modified OpenFlow Network.
