 note = {測度変換型測定のパケット損失率測定への応用について報告する．パケット損失は通常稀現象であるため，損失率をアクティブ測定によって精度良く求めるためには多量の測定パケットが必要となる．本稿では，事前に測定したパケットの遅延と損失率との相関情報と，測定パケットの遅延情報とを用いて，少数の測定パケットで時間平均損失率を高精度に推定する方法，および同方法によって得られた時間平均ロス率を測度変換を用いてユーザパケットロス率に変換する方法を提案する．また，これらの推定方式をシミュレーションにより検証する．, We have proposed a performance measurement method which combines active and passive measurement and applied it to packet-delay estimation. In this paper, we apply this method to loss-ratio estimation. Because packet loss rarely occurs in current networks, its measurement usually requires a huge number of probe packets, which imposes a non-negligible load on the networks. In our proposed method, the correlation between delay and loss is measured in advance, and at the time of measurement, the time-averaged loss ratio is estimated from the delay of probe packets using the correlation. We also apply our change-of-measure based method to estimate the loss ratio for user packets with high accuracy compared with the simple active measurement method.},
