Abstract:
In Software-Defined Networking, a network with distributed controllers can be partitioned into sub-networks as controller's administrative domains. Network partitioning could affect various aspects of network performances, such as controller load and reliability of controller's domains because network resources and topology are logically divided into sub-networks. By focusing on network partitioning, this paper handles the issue as a mathematical problem based on graph clustering and analyzes effective network partitioning methods with different indicators related Software-Defined Networking. The simulation results indicate the effectiveness of our clustering method in terms of the load balance of controllers and the reliability of controller domains.
