Title
(EN) FAST FORWARDING RE-CONVERGENCE OF SWITCH FABRIC MULTI-DESTINATION PACKETS TRIGGERED BY LINK FAILURES
(FR) RE-CONVERGENCE D'ACHEMINEMENT RAPIDE DE PAQUETS MULTI-DESTINATION DE MATRICE DE COMMUTATION DÉCLENCHÉS PAR DES DÉFAILLANCES DE LIAISON
Abstract
(EN)
A network device receives multi-destination packets from a first node and forwards at least a first of the multi-destination packets to another network device using a first multi-destination tree with respect to the network device. The network device detects that a link associated with the first multi-destination tree satisfies one or more criteria and, in response to detecting that the link satisfies the one or more criteria, selects a second multi-destination tree with respect to the network device. The network device forwards at least a second of the multi-destination packets to the other network device using the second multi-destination tree.
(FR)
L'invention concerne un dispositif de réseau qui reçoit des paquets multi-destination en provenance d'un premier noeud et achemine au moins un premier des paquets multi-destination à un autre dispositif de réseau à l'aide d'un premier arbre multi-destination par rapport au dispositif de réseau. Le dispositif de réseau détecte qu'une liaison associée au premier arbre multi-destination satisfait un ou plusieurs critères et, en réponse à la détection du fait que la liaison satisfait un ou plusieurs critères, sélectionne un second arbre multi-destination par rapport au dispositif de réseau. Le dispositif de réseau achemine au moins un second des paquets multi-destination à l'autre dispositif de réseau à l'aide du second arbre multi-destination.
