摘要
随着无人装备和智能技术在现代战争中的广泛应用,对战场通信网络的带宽、服务质量、实时性等方面的要求也越来越高。将软件定义网络的技术思想引入战术通信网络,能够给战术网络的运维管理、资源调度等方面的能力带来显著提升。但由于战术通信环境在带宽、时延、机动性等方面与民用通信环境存在较大差异,最初面向民用场景设计的软件定义网络无法直接应用到战术通信场景中,需要解决南向接口控制开销大等问题。因此,在标准OpenFlow规范的基础上,提出了从可靠UDP承载、消息聚合机制、南向交互模式优化等方面,对南向接口进行轻量化设计,有效降低南向接口控制开销,并通过仿真验证了所提方案的可行性,满足战术场景下的通信需求。
With the wide application of unmanned equipment and intelligent technology in modern warfare,the requirements for the bandwidth,service quality,and real-time performance and other aspects of battlefield communication networks are getting higher and higher.Introducing the technical ideas of software defined networks into tactical communication networks can bring significant improvements to the operation and maintenance management and resource scheduling,etc.of tactical networks.However,due to the huge differences between the tactical communication environment and the civilian communication environment in terms of bandwidth,delay and mobility,the software defined network originally designed for civilian scenarios cannot be directly applied to the tactical communication scenario unless the problems such as large control overhead of its southbound interface and others are solved.Therefore,based on the standard OpenFlow specification,a lightweight design of the southbound interface is proposed from the aspects of reliable UDP bearer,message aggregation mechanism,and southbound interaction mode optimization,and the control overhead of the southbound interface can be effectively reduced.The feasibility of the proposed scheme is verified by simulation,and the communication requirements in tactical scenarios can be met.
