摘要:

软件定义网络(software-defined networking,SDN)的出现为突破机载网络在航空集群作战应用背景下存在的性能瓶颈提供了全新的思路。针对航空集群机载网络的更新问题,提出适用于软件定义架构下航空集群机载网络的更新策略——可靠性增强的两阶段提交更新策略(reliability-enhenced two-phase commit,RE-TPC)。首先设计最高可靠性算法以及多路径算法搜索下发指令消息的高可靠路径。然后引入基于ACK(acknowledge)消息的确认机制和ACK消息高效融合传输机制,进一步提升网络更新过程的可靠性和实时性。仿真结果表明,与已有经典网络更新策略相比,所提更新策略能够有效提高更新的可靠性,同时更新持续时间更低、开销更小。

Abstract:

The emergence of software-defined networking (SDN) provides a new idea to break through the performance bottleneck of the airborne network in the context of aviation swarm warfare. In order to solve the problem of network update in the airborne network of the aviation swarm, a reliability enhanced two-phase commit network update strategy, which is suitable for the airborne network of aviation swarm under a software-defined architecture, is proposed. Firstly, the highest reliability algorithm and the multi-path algorithm are designed to search the highly reliable path of the instruction message. Then, ACK (acknowledge) message-based confirmation mechanism and ACK message efficient fusion transport mechanism are introduced to further improve the reliability, correctness and real-time performance of the network update process. The simulation results show that, compared with the existing traditional network updating strategies, the proposed update strategy effectively improves the reliability of network update, and at the same time, the duration as well as the cost of network update is lower.
