Abstract

La présente invention concerne un procédé et un système d'établissement d'un canal de gestion Ethernet flexible qui relèvent du domaine de la technologie Ethernet flexible. Dans la présente invention, il est déterminé si une couche PHY FlexE transporte des flux de services clients valides en combinaison avec un mécanisme de négociation de configuration fourni par un surdébit FlexE. Lorsqu'aucun flux de service client valide n'est transporté, un canal de gestion à bande passante élevée est créé et une signalisation de gestion est commutée vers le canal de gestion à bande passante élevée en vue d'une transmission. Lorsque des flux de services clients valides sont transportés, la signalisation de gestion est commutée vers un canal de gestion configuré par un utilisateur en vue d'une transmission et le canal de gestion à bande passante élevée est supprimé. De plus, avant la suppression d'une partie ou de l'ensemble des flux de services clients valides, une signalisation de gestion est commutée vers un canal de gestion non supprimé configuré par un autre utilisateur ou un canal de gestion à bande passante élevée établi en vue d'une transmission. Lorsque tous les flux de services clients valides sont supprimés, un canal de gestion à bande passante élevée est recréé et la signalisation de gestion est commutée vers le canal de gestion à bande passante élevée en vue d'une transmission, ce qui répond aux exigences d'occupation de bande passante élevée d'une signalisation de gestion.
