With the development of computer networks, the defects of traditional Transmission Control Protocol/Internet Protocol (TCP/IP)-based architecture have been amplified. Traditional computer networks are facing big challenges. To break a closed traditional network for eliminating defects and promoting network innovation, software-defined networking (SDN) has been proposed. In this chapter, we illustrate SDN and discuss future network research. We also give a brief overview of recent advances in SDN. Finally, we summarize our work related to SDN in datacenter networks.

“…The controller, managing all network devices such as routers and switches, can not only optimize flow routes and divert but also balance traffic to improve the network efficiency. Still, there are some challenges emerged when implementing a SDN architecture [2]. One of the most important aspect is SDN security, which won the attention of IETF and its profiles are defined [3].…”

Abstract. Compared with traditional networking, Software-Defined Networking (SDN) enables to solve the scalability, flexibility and other aspects of the problems. However, there still have some questions about previous relevant works for security control. Thus, in this paper, we analyze the new challenges and then propose a SDN security control architecture to strengthen security control. In such a structure, security control is separated from SDN controller as a separate security controller. The security controller is used to actualize security control through both flow-based protection and agency-based protection. The method of flow monitoring in SDN networks as well as the agency deployed in nodes helps the developers to implement the security functions. We then implement this architecture and verify its scalability and robustness.

“…In SDN, a network administrator has to implement a policy only in the controller, which is then replicated across the network's forwarding devices [2]. Despite immense popularity and ever increasing growth in deployment of SDNs, much research is needed as to whether SDN can be deployed on a large scale, that too with all the security [3].…”

Abstract-Software-Defined Networks have seen an increasing in their deployment because they offer better network manageability compared to traditional networks. Despite their immense success and popularity, various security issues in SDN remain open problems for research. Particularly, the problem of securing the controllers in distributed environment is still short of any solutions. This paper proposes a scheme to identify any rogue/malicious controller(s) in a distributed environment. Our scheme is based on trust and reputation system which is centrally managed. As such, our scheme identifies any controllers acting maliciously by comparing the state of installed flows/policies with policies that should be installed. Controllers rate each other on this basis and report the results to a central entity, which reports it to the network administrator.
