摘要: 针对航空集群各作战任务对网络性能需求的差异,研究了灵活耦合任务需求的航空信息网络切片问题。按照任务特性定义网络切片类型及性能特征,以任务资源需求为约束构建切片性能最优化整数规划模型,将网络切片构建问题分解为平台资源聚类和链路资源聚类2个步骤,提出了基于粒子群的平台资源聚类算法和基于感知节点的链路资源聚类算法。平台资源聚类阶段通过基于聚类因子排序的粒子群聚类算法进行迭代求解;链路资源聚类阶段,以各网络切片性能和链路负载率为优化目标,在平台资源聚类的基础上完成链路资源聚类。研究结果表明:所提算法构建的航空信息网络切片可满足不同任务对平台资源以及网络传输能力的需求,平台资源利用率和链路负载率显著改善。

Abstract: Considering the difference of network performance requirements of various combat missions in aviation cluster, the problem of aviation information network slicing with flexible coupling mission requirements is studied. According to the task characteristics, the network slice types and performance characteristics are defined, and an integer programming model for slice performance optimization is constructed with task resource demand as the constraint. The network slicing problem is decomposed into two steps:platform resource clustering and link resource clustering. A platform resource clustering algorithm is proposed based on particle swarm optimization, and a link resource clustering algorithm is proposed based on perceptive nodes. In the stage of platform resource clustering, the iterative solution is obtained by using the particle clustering algorithm based on clustering factor sequencing. In the link resource clustering stage, the performance of each network slice and the link load rate are optimized, and link resource clustering is completed on the basis of platform resource clustering. The results show that the aviation information network slice constructed by the proposed algorithm can meet the requirements of different tasks for platform resources and network transmission capacity, significantly improving the utilization rate of platform resources and link load rate.
