摘要
针对数据链系统仿真中对消息管理的需要,提出数据链系统消息管理模型。根据消息属性及传输过程,利用排队理论建立有反馈的闭环消息传输仿真框架,在非抢占优先模式和抢占优先模式下,分析系统对不同优先级消息的管理性能。分析结果表明,该模型能够满足传输消息的质量要求,其优先规则和闭环设计使系统运行安全、稳定。
According to the needs of the management of messages for data-link simulation system, this paper proposes a message management model of data-link system. It uses the messages＇ properties, the transmission process and the queuing theory to establish the messages generating and close-looped message transmission framework with feedback. It analyzes the management performance of messages with different priority under non-preemptive priority mode and preempted priority mode. Analysis result shows that this system can satisfy the requirement of message serves quality, and that priority rule and closed loop can keep the system safe and stable.
