Title (EN) COMMUNICATION SYSTEM AND CONTROL METHOD
(FR) SYSTÈME DE COMMUNICATION ET PROCÉDÉ DE COMMANDE
(JA) 通信システム及び制御方法
Abstract:
(EN) This communication system 1, which uses an SDN, is provided with: at least one SR transport device 130 which is provided between an SDN processing node 110-1-1 and an SDN processing node 110-2-2, and routes, on the basis of an SR code string allocated to the packet data, packet data received by the SDN processing node 110-1-1; and a transfer node 120-1 which is provided between the SDN processing node 110-1-1 and the at least one SR transport device 130, and allocates an SR code string to the packet data so that the packet data received by the SDN processing node 110-1-1 is transferred to the SDN processing node 110-2-2 through the at least one SR transport device 130.
(FR) La présente invention concerne un système de communication (1), qui utilise un SDN et qui comprend : au moins un dispositif de transport SR (130) qui est placé entre un nœud de traitement SDN (110-1-1) et un nœud de traitement SDN (110-2-2), et qui achemine, sur la base d'une chaîne de codes SR attribuée aux données de paquet, des données de paquet reçues par le nœud de traitement SDN (110-1-1) ; et un nœud de transfert (120-1) qui est placé entre le nœud de traitement SDN (110-1-1) et ledit dispositif de transport SR (130), et qui attribue une chaîne de codes SR aux données de paquet de sorte que les données de paquet reçues par le nœud de traitement SDN (110-1-1) sont transférées au nœud de traitement SDN (110-2-2) par l'intermédiaire dudit dispositif de transport SR (130).
(JA) SDNを利用する通信システム1は、SDN処理ノード110-1-1とSDN処理ノード110-2-2との間に設けられ、SDN処理ノード110-1-1が受信したパケットデータを、当該パケットデータに付与されているSR符号列に基づいてルーティングする、少なくとも1つのSRトランスポート装置130と、SDN処理ノード110-1-1と少なくとも1つのSRトランスポート装置130との間に設けられ、SDN処理ノード110-1-1が受信したパケットデータが少なくとも1つのSRトランスポート装置130を介してSDN処理ノード110-2-2に転送されるように、当該パケットデータにSR符号列を付与する転送ノード120-1と、を備える。
