面向卫星网络的延迟监测算法及仿真实现

研究测量分析网络内部链路延迟特征对了解网络行为至关重要,但当前地面网络延迟监测算法应用于卫星网络时存在诸多不准确问题,为此提出了一种面向卫星网络的延迟监测算法,它结合主动监测和被动监测的优点,采用统计分析方法测量卫星网络系统的报文流延迟分布特征。通过理论分析证明了算法的数学基础,并在网络仿真软件NS2下通过高、低轨道卫星网络模型对算法进行了仿真实验,实验结果表明,算法能够在较小的开销下解决卫星网络的延迟推测问题。

An Algorithm for Link Delay Monitoring and its Simulation in Satellite Network

The measurement and analysis of traffic delay of network is significant for understanding of the network behavior.However,when applied to the satellite network,the existing network delay monitoring algorithms encounter many problems.To solve these problems,a satellite network oriented delay monitoring algorithm is proposed in this paper.Combining the strong points of both active and passive monitoring methods,the novel algorithm measures the distributed features of the traffic flow delays in the satellite n...
