摘　　要：为了确定消息在多网数据链系统中传输时的时延指标是否满足作战需求,也是影响时延的主要因素,从分析多网数据链系统的拓扑结构中看出不同作战背景下的消息传输方式;应用OPNET实现了数据链系统仿真平台,仿真分析了不同消息传输方式的消息时延、站点响应时间、时延抖动等指标;结果表明站点数量、消息传输方式、站点服务策略等因素对上述指标有重要影响;作战过程中应依据作战需求合理确定站点数量,选择合适的消息传输方式和服务策略,以保证消息具有较好的时效性。In order to determine whether the time delay of message transmitting in multinet datalink system is within the need for combat and to find out the main factors influencing it, this paper analyzes the message transmitting ways under multinet topology and varying combat conditions. The simulation is implemented using OPNET, in which indexes such as time delay, node response time and delay variation of different message transmitting ways are analyzed. Simulation results show that these indexes are significantly affected by. such factors as number of nodes, message transmitting way and service strategy of node. The paper suggests that the above factors should be well tackled to guarantee the time delay of messages.
