A Secure Virtual Controller for Traffic Management in SDN

There is a need for developing an efficient, robust, and secure execution platform for Software-defined networking (SDN) concerning the dynamic network service offerings. In this paper, we present a secure virtual controller (SVC) architecture that satisfies the benchmark characteristics and provides robustness, fine-grained modularity, strong isolation. Our proposed architecture supports network function virtualization, which is responsible for executing different network functions on various traffic flows. We designed two new network functions that provide vigorous security enforcement and energy-efficient load distribution in SDN. The security function is realized using signaling game theory, and the load distribution is accomplished using a heuristic-based approach. Finally, the performance of our proposed architecture is evaluated and compared with the state-of-art research works and the commercially available controller Floodlight.
