Abstract
(EN)
Frame transfer on a network where an Ethernet (R) frame sent from a source on the network is forwarded to a predetermined destination. An extended frame is created by adding an extension tag to a received Ethernet (R) frame wherein forwarding information on forwarding to an edge node that is the exit side of a destination host is included in the extension tag. The nodes on the network relay a data frame to the edge node on the exit side according to the forwarding information included in the extension tag that is added.
(FR)
L'invention concerne un transfert de trame sur un réseau dans lequel une trame Ethernet (R) est envoyée d'une source du réseau vers une destination déterminée. Une trame élargie est créée par addition d'un repère d'élargissement à une trame Ethernet (R) reçue, un information d'acheminement vers un noeud en bordure, constituant le côté de sortie d'un hôte de destination en bordure, étant comprise dans le repère d'élargissement. Les noeuds du réseau relaient une trame de données vers le noeud en bordure sur le côté de sortie selon l'information d'acheminement contenue dans le repère d'élargissement qui est ajouté.
(JA)
 ネットワーク上の送信元から送られるイーサネット(R)フレームを所定の送信先に転送するネットワークにおけるフレーム転送において、入力されたイーサネット(R)フレームに、送信先となるホストへの出口側となるエッジノードへのフォワーディング情報を含む拡張タグを付加して拡張フレームとし、ネットワーク上の各ノードが、付加された拡張タグのフォワーディング情報に基づいてデータフレームを中継し、出口側のエッジノードへ転送する。
