Outline of Final Research Achievements |
Control planes of Software Defined Networking (SDN) have faced scalability issues because they have been widely applied for large scale networks. It is known that the issues are caused from three points: (1) heavy loads of controllers which dominate all switches in an SDN network, (2) long delay between a controller and a switch and (3) limitation of the number of control rules in a switch. In order to reduce the number of the control rules for failure recovery which is a necessary function of a network, this paper proposes a rule decision method by utilizing the fundamental tie-sets of the graph theory. For alleviating the heavy loads and effects of the long delay, our switch clustering method can construct an effective control plane with multi-controllers sharing global information.
