Abstract

　ネットワークの近傍性情報を用いながら、ピアの論理識別子の分布を均一にし、特定のピアに負荷が偏らないオーバレイネットワークを構築できるようにしなければならない。 　各ピアが、オーバレイネットワークに参加する場合に、ピア参加手段４１５が受け付ける参加要求の指示にもとづいて、ネットワーク計測手段４１６が複数のランドマーク４５０，４６０，４７０に対する通信の応答時間を測定し、座標計算手段４１７が取得した応答時間にもとづいて当該ピアの多次元の位置情報（座標）を算出し、空間充填曲線変換手段４１８が空間充填曲線を用いて多次元の位置情報を一次元の位置情報に変換し、空間分布関数適用手段４１９が一次元の位置情報に空間分布関数を適用して均一化された一次元の情報を取得する。そして、ピア参加手段４１５が一次元の情報と論理識別子空間の積をとることによって当該ピアの論理識別子を決定する。
