Enabling disaster-resilient SDN with location trustiness

Software-Defined Networking (SDN) is promised as future of Internet which provides centralized network management. It provides detail information of underlay routers and makes a decision based on the global view of the current network. However, in the case of occurring unexpected natural disasters such as earthquakes or typhoons, the network infrastructure faces many challenges such as links and devices failures. Therefore, how to recover the network quickly under disaster situations is particularly essential for reliable SDN. In this paper, we propose a novel approach to enable disaster resilient SDN networks with location trustiness. We first present a method for calculating the trustiness of a location based on multimodal information including earthquake events and disaster sensor data. Then, we design a system to support disaster resilient SDN based on location-trustiness. To evaluate the feasibility of the proposed system, we simulate the responses to the network which affected by earthquake events. The results show that our approach reduces the recovering time significantly.
