摘要/Abstract

摘要： 目前基于数据链通信的服务器节点大多采用FCFS的服务模型进行实时数据传输,并没有根据实时数据的时效性及优先级提供良好的QoS控制。提出一种基于数据链通信的实时数据传输QoS控制算法,其通过在应用层对实时数据进行QoS分级并采用一种最早截止时间优先的优先级可控制算法(PC-EDF)进行调度,以保障在数据链通信带宽受限的条件下实时数据端到端传输的低时延以及可靠性。实验结果也验证了该方法的有效性。

关键词: 数据链,QoS控制,实时

Abstract: In the Tactical Data Link the real-time data are translated based of the FCFS module,which is not considering about the priority and QoS control of the real-time data．QoS control of the real-time data translating based on the Tactical Data Link method was proposed.A QoS classification of the real-time data and the priority controlled earliest deadline first algorithm were provided in the application layer,which could guarantee the network end to end delay and reliability in the restricted bandwidth condition.Experimental results show that it’s efficient.

Key words: Tactical data link,QoS control,Real time
