SpaceFibre星载网络服务质量实现研究
|
摘要
为实现SpaceFibre星载网络中短时间内大量实时数据流的可靠传输,满足不同空间任务的服务质量(QoS)要求,提出一种基于二进制序列调度的新算法。该算法根据星载网络中的不同流量特征生成对应的二进制调度序列,可以很好地解决复杂数据流量的调度与不同数据流量带宽需求之间的权衡问题,实现了SpaceFibre协议框架下的QoS功能。最后给出了算法的延时性能分析与实例仿真,结果表明由该算法生成的二进制序列调度机制在传输时延上有着较好的灵活性和确定性。
A new algorithm based on the binary sequence scheduling is proposed in order to achieve the reliable transmission of the massive real-time data streams in a short time on the SpaceFibre onboard network and meet the quality of service(QoS) requirements for different space tasks. The algorithm generates the corresponding binary scheduling sequence according to different traffic characteristics of the onboard network. The tradeoff between the scheduling of the complex data flows and the bandwidth requirements of different data traffics can be well solved, and the QoS function under the framework of the SpaceFibre protocol can be realized. Finally, the delay performance analysis and simulation results of the algorithm are given, which show that the binary sequence scheduling mechanism generated by the algorithm has better flexibility and certainty on the transmission delay.
