The invention relates to a method, a network node and a data transmission system for packet-switched data transmission in a data transmission network that comprises at least two network nodes (DXT, BS) for receiving and transmitting packets. The packets (3, 4, 5, 6) sent from the first node (DXT) to the second node (BS) are packets whose destination address indicates the second node as the next node, and the first node (DXT) identifies the destination addresses and data transmission connections (A, B, C, D) associated with the received packets from the identification data contained in each packet. To reduce the risk of a packet not arriving in time, the method comprises reception of a control signal (8) in the first node (DXT), the signal comprising information on the data transmission connection of the packet to be sent next to the second node (BS), and transmission of the packet associated with the data transmission connection indicated by the control signal (8) to the second node (BS).
L'invention concerne un procédé, un noeud de réseau et un système de transmission de données permettant la transmission de données commutée par paquets dans un réseau de transmission de données comprenant au moins deux noeuds de réseau (DXT, BS) pour la réception et la transmission de paquets. Les paquets (3, 4, 5, 6) envoyés par le premier noeud (DXT) au second noeud (BS) sont des paquets dont l'adresse de destination indique le second noeud comme noeud suivant, et le premier (DXT) identifie les adresses de destination et les connexions de transmission de données (A, B, C, D) associées aux paquets reçus à partir des données d'identification contenues dans chaque paquet. Afin de réduire le risque qu'un paquet n'arrive pas à temps, le procédé comprend la réception d'un signal de commande (8) dans le premier noeud (DXT), le signal comprenant des informations relatives à la connexion de transmission de données du paquet à envoyer ensuite au second noeud (BS), et la transmission du paquet associé à la connexion de transmission de données indiquée par le signal de commande (8) au second noeud (BS).
