卫星网络QOS监测技术研究

Research of QOS Monitoring for Satellite Network

在卫星骨干网网关上部署开发高效可靠的监测方法对保证卫星网的正常运行具有重要作用。本文提出了一种可调的主/被动综合型监测系统,根据测量要求的置信水平和置信区间不同,通过反馈控制算法调整探测报文的发送间隔,可以得到各种级别和精度的卫星网络QOS参数。最后利用LEO卫星网络模型对该算法作了仿真试验,并取得了较为满意的效果。

It is very important to deploy the efficient QOS monitor system in satellite network. This paper presents an adjustable monitor system combining active and passive methods. According to a set of confidence level and confidence interval, Through adjusting the gap between the probe packets by a feedback control algorithm, the network QOS parameters of different precisions and levels can be achieved. Simulation results prove that the prototype system could give the QOS measurements in the satellite networks with only a little extra traffic.
