摘　　要：SDN具有转控分离的架构特点,骨干网具有带宽资源大、链路稳定的优势,SDN在骨干网中的应用研究案例较多,但由于接入网先天性带宽较低的不足,SDN在低带宽战术通信方面的研究还较少。主要研究在战术接入网环境下SDN的应用,提出了一种针对战术接入网拓扑条件下的SDN架构应用方案以及在低带宽战术通信场景下应用SDN需要突破的关键技术,对战术通信网络从传统纯分布式封闭网络架构到SDN开放式架构的全面应用的平滑过渡具有一定的参考价值。SDN has the characteristics of a separate architecture for transfer and control,and the backbone network has the advantages of large bandwidth resources and stable link.Hence there are many research application cases of the SDN in backbone network.However,due to the lack of congenital bandwidth of the access network,there is still scarce research on the SDN in low-bandwidth tactical communication.This paper mainly studies the SDN application in tactical access network environment,and provides an application solution of the SDN architecture for tactical access network topology and the key technologies to break through in the application of SDN in low-bandwidth tactical communication scenarios.It has a certain reference value for the smooth transition of tactical communication network from traditional distributed closed network architecture to the SDN open architecture.
