Abstract: Software-Defined Networking (SDN) provides a new opportunity to break the bottleneck caused by the rigidity of airborne network functions. Aiming at the problem of control node failure in the software-defined airborne network control domain, we propose a transmission node migration strategy based on time delay and load balancing to transfer the transmission nodes in data plane that are controlled by the failed control node to other normal control nodes to restore the normal control of the network. With the migration delay and load balancing rate as the goal, a migration optimization model is established, and the transmission node migration algorithm based on delay and load balancing is proposed to guide the migration action in the data plane, and finally the two performance goals are comprehensively balanced. The experimental results show that, compared with the Distance Closest Migration (DCM) strategy and the Distributed Hopping Algorithm (DHA) strategy, the proposed strategy makes a suitable compromise between the migration delay and the load balancing rate, avoids excessive migration delay or unbalanced control node load, and effectively solves the problem of airborne network fault recovery.

Key words: airborne networks, Software-Defined Networks(SDN), data plane, migration delay, load balancing rate
