Abstract

With the rapid development of Information Communication Technology (ICT), the traditional networks are facing tremendous challenges. In recent years, the network security has been constantly affected by various factors (e.g., the damages of natural disaster, network intrusion, and limited properties of network). It is urgent to make some appropriate adjustments for current network architecture. Software Defined Networking (SDN) and Information-Centric Networking (ICN) bring innovation, speediness in recovery and reconfiguration for network computing. SDN decouples the forwarding plane from controlling plane, thus moving the control logic from a node to the central controller for the real-time supervision. ICN separates the resources from the location, to make the host-oriented model transform into content-centric model, which promotes the utilization of network resources and relieves the explosive growth of network flow. In this paper, we present a novel safety network model by applying SDN and ICN to the network recovery and reconfiguration. The proposed model prevents the network congestion and monitors the network status in real time. The system can be quickly restored after being damaged, which improves the network survivability. We considered three scenarios (natural disaster, malicious damage, and system self-defect) to discuss the proposed model. We simulated the situation where system was damaged and calculated the recovery time. The simulation results show that recovery time of system is shorter in the proposed model than in traditional network. Finally, we explore the broader perspectives for the network security.
