数据链系统消息的时效性对其战术价值具有重要影响。设计了数据链系统仿真平台,基于该平台建立了多网数据链网络拓扑、通信协议、通信链路、消息生成等模型;分析了消息格式转换过程以及不同作战背景下的消息传输方式;仿真比较了不同传输方式下的消息时间延迟、站点响应时间、消息时间延迟抖动等指标。结果表明,上述指标受站点数量、消息传输方式、站点服务策略等因素的影响很大。
Transmit delay of message has great influence on its tactical value in datalink system.This paper analyzed the message transmit process in datalink system.A datalink system simulation platform was established and multi-net data-link topology,communication protocol,communication route and message generating were built.The transformation process of message format and ways of transmitting were analyzed in details.The message delay,response time and delay variation under different transmitting ways were compared using above models.Simulation results show that the indexes are significantly influenced by such factors as number of nodes,message transmitting way and service strategy of nodes.
