Title (EN) VIRTUAL ROOT BRIDGE
(FR) PONT RACINE VIRTUEL
Abstract: front page image
(EN)A network includes a plurality of network clusters. Each network cluster includes a plurality of nodes. At least one of the plurality of nodes includes a portal node. A portal node is a node with at least one link that crosses a boundary of the network cluster. Each portal node is configured to communicate detection packets for detecting the existence of other portal nodes within the network cluster. Each portal node is configured to communicate with nodes within the network cluster associated with the respective portal node to indicate that the respective portal node is a predetermined number of hops away from a virtual root bridge associated with the network cluster.
(FR)La présente invention concerne un réseau comportant une pluralité de grappes de réseau. Chaque grappe de réseau comporte une pluralité de noeuds. Au moins un de la pluralité de noeuds comprend un noeud portail. Un noeud portail est un noeud avec au moins un lien qui traverse une frontière de la grappe de réseau. Chaque noeud portail est configuré pour la communication de paquets de détection permettant la détection de l'existence d'autres noeuds portail au sein de la grappe de réseaux. Chaque noeud portail est configuré pour la communication avec des noeuds associés au noeud portail respectif pour indiquer que le noeud portail respectif est éloigné du pont racine virtuel associé à la grappe de réseau par un nombre de sauts prédéterminé.
