Integrated SDN and non-SDN network management approaches for future internet environment

Abstract

For years, computer scientists have been dreaming of innovating Internet in terms of performance, reliability, energy efficiency, security, and so on. However, it is nearly impossible to carry out practical large-scale experiments and verification, since new software and programs are hardly evaluated on the current Internet environment where routers and switches are totally closed. In this context, Software Defined Networking (SDN) concept has been introduced to deploy software-oriented and open programmable network coupled tightly with traditional Internet (non-SDN) environment. This tight integration results in easy and efficient deployment of SDN domains into non-SDN infrastructure, but it is also required that integrated management methods for SDN and non-SDN be developed. This paper proposes how SDN and non-SDN can be managed in an integrated manner in terms of two aspects: (1) non-SDN driven management approach and (2) SDN oriented management approach, in order to achieve reliable Future Internet environment. © 2013 Springer Science+Business Media Dordrecht(Outside the USA).
