It is revealed that the rtt distribution is best fitted by a constant plus a " skewed right " gamma distribution . the adjacent and near - adjacent delays in the time series are linearly dependent rather than random . it is also indicated that there are only weak or no nonlinear correlations among rtt observations 分析表明rtt时间序列与一个常数加右偏的分布极其相符合；在时间序列中相邻的及相近的时延之间是线性相关而不是不相关的；也可以看到在两个采集的rtt观测值之间只有微弱的或没有非线性相关性。
