摘要:

通过"干涉模型"分析了"探测报文对"发送时间间隔与路径中背景流量之间的相互关系,并开发了一个适用于卫星通信网络的快速报文组算法.最后利用GEO/LEO卫星通信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.

关键词: 卫星通信网络, 报文组, 带宽测量

Abstract:

Existing algorithms for bandwidth measurement are unable to achieve balance between real time performance and reliability for satellite communication networks.To solve the problem, an intervening model is proposed to analyze the relationship between packet pair dispersion and cross traffic.Using this model, packet pair spacing with higher accuracy can be achieved.An algorithm of fast probe packet group is also developed.Results of simulation under the GEO/LEO satellite network model show that the algorithm can measure the bandwidth with high speed and low network resource cost.

Key words: satellite network, bandwidth measurement, packet group
