随着**任务日益复杂, 未来航空作战是一种需要多种数据链资源融合共享的多平台联合作战。软件定义网络(SDN)的发展为多数据链网络的全局管控提供了全新的设计思路。充分考虑多种链路并存下的网络资源融合情况, 提出了基于SDN的多数据链网络控制架构。通过对数据链子网映射提出基于节点需求的子域划分(NDSP)算法, 实现了物理子域的合理划分, 然后在此基础上利用改进多目标模拟退火算法(ISA)进行中心交互节点的选取, 完成了对作战网络的全局管控。实验结果表明, 所提的NDSP算法在多数据链融合的网络中进行子域划分时具有更好的应用性, 而ISA算法对网络交互路径的平均时延和平均失连率有显著改善效果。

With the increasing complexity of military missions, the future combat system is a multi-platform joint operation that requires the integration and sharing of multiple datalink resources. The development of Software Defined Network (SDN) provides a new design idea for the global management and control of multi-datalink network. A multi-datalink network control architecture based on SDN is proposed by fully considering the network resource fusion of multiple links.A Node D emand based Sub-domain Partitioning(NDSP) algorithm is proposed through datalink sub-net mapping, which realizes the rational partitioning of physical sub-domains. Then, the improved multi-objective simulated annealing algorithm (ISA) is used to select the central interactive nodes, and thus the network is globally controlled.The experimental results show that the NDSP algorithm has better applicability for sub-domain partitioning in the multi-datalink fusion network, and the ISA algorithm can significantly decrease the average delay and average failure rate of network interaction path.
