Abstract

L'invention concerne un procédé et un dispositif de transmission de données de flux. Le procédé consiste : à transmettre des premières données de flux d'un premier client à un deuxième client en fonction d'un trajet de transmission, le trajet de transmission passant à travers des nœuds de transmission cibles multiples et au moins un nœud de transmission cible possédant un nœud de transmission associé ; à recevoir des secondes données de flux transmises par le deuxième client aux nœuds de transmission cibles ; et à pousser les secondes données de flux des nœuds de transmission cibles au premier client et au moins un troisième client au moyen du nœud de transmission associé. Ainsi, dans des modes de réalisation de la présente invention, l'établissement d'un nouveau trajet de transmission pour les secondes données de flux est économisé, le temps d'établissement de trajet est réduit et la transmission de données de flux en temps réel est assurée. Selon la présente invention, lorsqu'un grand nombre de données de flux existe en même temps dans un réseau de transmission de données de flux, une opération de synthèse du grand nombre de données de flux est effectuée au niveau d'un client utilisateur ; ainsi, il n'est pas nécessaire d'utiliser un système de synthèse, le problème de retard causé par la transmission multi-système est résolu et le surdébit du système est également réduit.
