With the development of virtualization and cloud technology, cloud data centers have been emerging for ICT infrastructure market. In order to link resource pools (i.e., servers, storages, and switches) over distributed data centers, tunneling-based overlay networking can maintain L2 connectivity with reasonable scalability. However, in properly managing all the switches and tunnels, the complexity of underlying network topology causes uncontrollable difficulties. Thus, in this paper, we discuss how to automatically manage overlay virtual networking by employing an openflow-based OvN-Manager (Overlay vnetworking Manager) tool. The verification results for implemented OvN-Manager tool are also presented over OF@TEIN international SDN-Cloud testbed.
