Software Defined Networking (SDN) enables highly flexible routing and traffic engineering. The network using the centralized SDN control can be operated by globally viewing the entire network. On the other hand, the network operation of the routing and traffic engineering based on internal network traffic monitoring does not immediately perform the network recovery specifically in case of the multiple network failures induced by the large scale disaster such as Great East Japan Earthquake. Hence, we will investigate the new network operation utilizing the external information abstracted from the social data. The social data contains the real-time user experience of the network quality degradation due to the emergency events, natural disaster etc. and useful for the immediate network recovery. The integration of the social data with SDN will enable the new network operation. In order to obtain the real-time information from the social data, Twitter is most relevant for our purpose. First, we constructed the SDN enabled network testbed in the wide area network controlled by the centralized system using th northbound interface (NBI). Next using the testbed, the network restoration experiment was successfully performed by the network path computation algorithm using actual Tweet logs of the Great East Japan Earthquake.
