Software Defined Networking based Information Centric Networking: An Overview of Approaches and Challenges

摘要

ICN (Information-Centric Networking) is a traditional networking approach which focuses on Internet design, while SDN (Software Defined Networking) is known as a speedy and flexible networking approach. Integrating these two approaches can solve different kinds of traditional networking problems. On the other hand, it may expose new challenges. In this paper, we study how these two networking approaches are been combined to form SDN-based ICN architecture to improve network administration. Recent research is explored to identify the SDN-based ICN challenges, provide a critical analysis of the current integration approaches, and determine open issues for further research.
