N2 - In SDN, a network can be controlled using in-band or out-of-band control networks. Most of current research for SDN focuses on an out-of-band network. In this network, the controller is directly connected to every router or switch in one-to-one manner. However, out-of-band networks are expensive to build due to the requirement of a separate network and cannot provide integration with previous network infrastructure such as legacy, DSL, and WSN, etc. Also, this network may not be feasible in realistic scenarios. To solve the above problem, SDN is required to be implemented for an in-band network. Because control and data traffics share the same network links, fast recovery is one of important problems in SDN. In this paper, we propose a fast recovery scheme for in-band OpenFlow networks. We design a detour planning to reduce the control message overhead. To evaluate performance of proposed scheme, we have developed laboratory scale in-band SDN testbed. The experimental results show that the proposed scheme reduces control overhead and guarantees the network QoS.
