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.

1 Introduction There have been drastic demands over the past years in the Internet, compared to the earlier Internet designs [1]. One of the challenges is the requirement of open networking that makes it possible for users to innovate Internet by experimenting and applying newly developed technologies over practical large-scale networks. Internet innovation known as Future Internet, currently, is deeply involved with network performance, reliability, energy efficiency, security, etc., while Internet is entirely closed not to allow any new user-oriented software to be installed and tested on. Only can network vendors access and control the network devices on Internet regarding programmability, reconfiguration, and any innovative efforts. Therefore, various researches have been performed to cope with the new user demands, and one of them is Software Defined Networking (SDN) with OpenFlow protocols [2] that has invoked significant interest in reconsidering traditional aspects of Internet architecture and design. Two important features of SDN are (1) implementation of network control plane decoupled from data plane (network forwarding hardware), and (2) relocation of control plane from hardware switch equipped with a typical low performance CPU. Another interesting feature of SDN is that it can easily be int
