Abstract
(EN)
There is provided a first network node arranged to communicate with a second network node, the first and second network nodes being connected by a first path and a second path. The first path uses a first communications network and the second path uses a second communications network. The first network node has a first mode and a second mode of operation, such that in a first mode traffic between the first and second network nodes is transmitted over the first path and not the second path, and in a second mode traffic between the first and second network nodes is transmitted over the first path and the second path. The network node comprises a mode selector arranged to select the second mode of operation when the demanded amount of traffic between the first and second network nodes exceeds a threshold value for a period of time.

L'invention concerne un premier nœud de réseau agencé pour communiquer avec un second nœud de réseau, les premier et second nœuds de réseau étant reliés par un premier trajet et un second trajet. Le premier trajet utilise un premier réseau de communication et le second trajet utilise un second réseau de communication. Le premier nœud de réseau comprend un premier mode et un second mode de fonctionnement, de telle sorte que, dans un premier mode, le trafic entre les premier et second nœuds de réseau est transmis sur le premier trajet et non sur le second trajet, et dans un second mode, le trafic entre les premier et second nœuds de réseau est transmis sur le premier trajet et le second trajet. Le nœud de réseau comprend un sélecteur de mode conçu pour sélectionner le second mode de fonctionnement lorsque le volume de trafic demandé entre les premier et second nœuds de réseau dépasse une valeur seuil pendant une période.
