Abstract:
This paper proposes the layered control plane of OpenFlow networks with multiple controllers. Our method log- ically partitions an OpenFlow network and assigns controllers to the partitioned networks as their administrative domains. In addition, this paper focuses on the relationship between the network partitioning and the amount of global network information shared among controllers. Then, this paper handles the issue as a mathematical problem based on graph clustering and analyzes effective network partitioning methods in reducing the amount of global network information.
