Abstract:Multi‐controllers can effectively improve the scalability and stability of the control plane in software‐defined networking (SDN) and is becoming a promising solution in large‐scale networks. In this article, we present a research survey for multi‐controller SDN control plane. We categorize the multi‐controller research into two aspects: homogeneous control plane and heterogeneous control plane. For homogeneous control plane, the network uses multiple same types of controllers to achieve the integrative contro… Show more
