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. Keywords: SDN, ICN, Network Survivability,
