摘　　要：海上战术通信网络通常具有延迟高、丢包率高、带宽小等特点,同时终端的频繁移动以及天气海况等自然因素的影响也会造成链路通信质量下降,降低数据传输效率。针对这一问题,设计一种基于带宽估计的分级传输系统。该系统以数据报文的发送节拍为采样周期,动态估算实时的传输带宽,并以此选择符合当前传输能力等级的数据报文进行发布。实验结果表明,该系统能较好地满足体系化协同作战场景下战场态势生成和战术分析业务对目标级数据以及特征级数据在延时和丢包率方面的不同需求,提高了海上战术通信网络的传输性能。Maritime tactical communication network usually has the characteristics of high delay,high packet loss rate and low bandwidth.At the same time,the frequent terminal movement and the influence of natural factors such as weather and sea conditions will also cause the communication quality of link and reduce the data transmission efficiency.To solve this problem,a hierarchical transmission system based on bandwidth estimation is designed in this paper.The system dynamically estimates the real-time transmission bandwidth by taking the sending beat of data packets as the sampling period,and then selects the data packets that meet the current transmission capability level for publication.The experimental results show that the system can well meet the different requirements of target-level data and feature-level data on delay and packet loss rate in systematic battlefield situation generation and tactical analysis,and improve the transmission performance of maritime tactical communication network.
