 note = {筆者らはこれまでの検討で，多重化IPトラヒックが時間スケールの小さい領域でポアソン的な性質を示すことを原理的に示し，これを局所ポアソン性と定義した．更に，有限バッファ待ち行列システムの性能評価において，入力トラヒックが局所ポアソン性を持つと，特定範囲のバッファサイズに対し，入力をポアソン過程として近似評価（ポアソン近似）できることを示唆した．本稿では，まず，ポアソン近似可能なバッファサイズ範囲を解析的に導出する．更に，実測IPトラヒックを入力して，有限バッファ待ち行列システムのパケット損失率を評価することにより，実ネットワーク上でのポアソン近似の適用性と，導出したバッファサイズ範囲の妥当性を検証する．その結果，エンドユーザからコアネットワーク方向へ流れる多重化IPトラヒックと，ピアツーピアアプリケーションの多重化IPトラヒックに対するポアソン近似の適用性を確認した．また，導出したバッファサイズ範囲を目安として，ポアソン近似の適用可否を判断できることを確認した．, Our previous works have presented the scenario that aggregated IP traffic exhibits the Poisson-like characteristic within small time scales. We call the characteristic as the local Poisson property. We have also indicated that the packet loss probability of a finite-buffer queue with the local Poisson input can be estimated by evaluating the finite-buffer queue with the corresponding Poisson input when the buffer size is within a certain range. We refer to the evaluation technique as Poisson approximation. In this paper, we analytically derive the appoximate range of the buffer size within which a finite-buffer queue with a local Poisson input can be evaluated by the Poisson approximation. Next, we confirm the applicability of the Poisson aproximation to actual IP traffic and the feasibility of the buffer range, by examining the packet loss probability of a finete-buffer queue with the input of measured IP traffic. The results indicate that the Poisson approximation works with certain types of actual IP traffic such as aggregated traffic from many end-users to a core network and aggregated peer-to-peer traffic. They also suggest that the approximate range of buffer size gives us a good indication to judge the applicability of the Poisson approximation.},
