Abstract:

For the expandability in the control plane of the future airborne optical information network, based on the concept of software defined network, the network framework of software defined airborne information network is proposed. The strategy of controller placement in software defined airborne information network with microwave/laser hybrid links is analyzed. With the outage probability of network nodes and links as the parameter, and the network reliability as the object function, an integer programming optimization model is established to solve the problem. A hybrid optimization algorithm integrated of artificial immune strategies, niche ideas and the improved genetic algorithm is proposed to obtain a better strategy of controller placement. Simulation results show that the reliable based integer programming model could accurately describe the controller placement problem in the software defined airborne network, which provides reference for the optimal controller placement.
