基于SDN的战术通信网络架构研究

战术通信网络具有高动态、弱连接、低带宽和多链路备份等特性，软件定义网络（software defined network，SDN）技术通过传统网络控制设备软硬件解耦，将核心控制功能软件化，通过集中控制策略获取全局视图，从而实现资源的灵活调度与信道资源的高效利用，推动战术通信网络朝着更加智能化的弹性适变网络发展。首先介绍了SDN的发展现状及优势，分析了传统架构战术通信网络的若干问题，并对SDN技术在外军战术通信领域的应用情况进行了分析，提出了SDN在军事通信领域应用的可行性思路，对应用场景进行了构想，最后对SDN在军事通信领域的应用可行性进行了总结。

Research on SDN based tactical communication network architecture

Tactical communication networks has high dynamic, weak connection, low bandwidth, multi-link backup, SDN (software defined network) technology decouples from hardware and software through traditional network control devices, software the core control functions, get a global view through centralized control policies, so as to realize the flexible scheduling of resources and the efficient utilization of channel resources, promote the development of tactical communication networks more intelligent and flexible adaptive.The development status and advantages of software defined network were firstly introduced, the problems of traditional architecture of tactical communication networks were analyzed, including the application of SDN in the field of foreign military tactical communication.Then, the feasible idea of the application of SDN in the field of military communication was put forward, as well as the application scenarios were conceived.Finally, the feasibility of the application of SDN in military communication was summarized.
