| 講演名 | 2015-03-03 15:10 Efficient information sharing among distributed controllers of OpenFlow network with bi-connectivity ○Junichi Nagano・Norihiko Shinomiya（Soka Univ.）  NS2014-259 |

| 抄録 | （和） | Control planes of Software Defined Networking have faced a scalability issue because they have been widely applied for large scale networks. To address this issue, control planes with multi-controllers such as Onix and HyperFlow have been proposed in which the controllers share global network view. Since the global network view includes topology, states and events of a network, shared information among controllers could become larger when governed network is large and complicated. Thus, Onix have proposed information reduction method by abstracting switches as a single virtual switch. However, there is a lack of discussion about reliability of virtual switches that depends on topology of the abstracted networks. To improve reliability of the virtual switches, there are two viewpoints: (1) administrative areas of controllers, and (2) limitation of abstraction areas. Hence, this paper proposes construction method of more dependable virtual switches focusing on bi-connectivity and reduction method of shared information using the virtual switches. Our experimental results show that our method can improve reliability of virtual switches and curb the number of edges in a federation graph that is regarded as shared information. |
