Abstract:

To solve the problem of control node failure in the control domain of software-defined airborne network of the aviation swarm, the problem of failure recovery is transformed into the issue of leader election, and an election-based software-defined airborne network controller failure recovery mechanism is proposed, and the transmission node is elected as a new control one in the control domain. To optimize the performance of the new control node, the three parameters of the average transmission delay, the maximum request amount and the average failure rate of each transmission node are combined to calculate the weight of the transmission node. The election priority is defined according to the weight, and a priority-based control node election (PBCNE) algorithm is proposed. The experimental results show that compared with the existing election algorithms, the complexity (number of messages and amount of time) of the PBCNE algorithm has been significantly reduced, the failure recovery delay has been effectively reduced, and the controller failure can be recovered quickly and efficiently.

Key words: airborne network, software-defined networking (SDN), election weight, priority, failure recovery delay
