Abstract
(EN)
A communication system comprises: an information collection device (20) which collects, from an edge node (11), INT information attached to a packet, indicating passing time of an input port and passing time of an output port of each node (10); an information selection device (30) which selects, among the collected pieces of time stamp information, time stamp information corresponding to a selection condition; an information processing device (40) which performs prescribed calculation processing on the basis of the selected time stamp information; and an NW apparatus control device (50) which controls a network apparatus on the basis of the result of the calculation by the information processing device (40).
(FR)
L'invention concerne un système de communication qui comprend : un dispositif de collecte d'informations (20) qui collecte, à partir d'un noeud de bord (11), des informations INT rattachées à un paquet, indiquant le temps de passage d'un port d'entrée et le temps de passage d'un port de sortie de chaque noeud (10) ; un dispositif de sélection d'informations (30) qui sélectionne, parmi les éléments collectés d'informations d'horodatage, des informations d'horodatage correspondant à une condition de sélection ; un dispositif de traitement d'informations (40) qui effectue un traitement de calcul prescrit sur la base des informations d'horodatage sélectionnées ; et un dispositif de commande d'appareil NW (50) qui commande un appareil de réseau sur la base du résultat du calcul par le dispositif de traitement d'informations (40).
(JA)
通信システムは、エッジノード(11)から、パケットに付与された各ノード(10)の入力ポートの経由時間と出力ポートの経由時間とを示すINT情報を収集する情報収集装置(20)と、収集されたタイムスタンプ情報のうち、選択条件に応じたタイムスタンプ情報を選択する情報選択装置(30)と、選択されたタイムススタンプ情報を基に所定の計算処理を行う情報処理装置(40)と、情報処理装置(40)による計算結果を基にネットワーク機器を制御するNW機器制御装置(50)と、を有する。
