Patent

CA 2398009

According to the invention, in order to control the access of traffic streams (VS) to the communications network (KN), an available capacity (VK), placed at the disposal of an access node (ZK) for transferring traffic streams (VS) to said communications network (KN), is determined from an access node (ZK) of the communications network (KN), taking into account the total transfer capacity (G) of the communications network (KN). The available capacity (VS) is notably redetermined whenever the routing information (RI) of the access node (ZK) is modified. An access control of this type guarantees the quality of service required in a connectionless communications network.

Selon la présente invention, à partir d'un noeud d'accès ZK d'un réseau de communication KN, une capacité disponible VK, qui est à la disposition du noeud d'accès ZK pour la transmission de flux de trafic VS sur le réseau de communication KN, est déterminée afin de commander l'accès de flux de trafic VS au réseau de communication KN et ce, avec prise en compte de la capacité de transmission totale G du réseau de communication KN. La capacité disponible VS est notamment de nouveau déterminée lorsque les informations d'acheminement RI du noeud d'accès ZK sont modifiées. Ce genre de commande d'accès permet d'assurer une qualité de service exigée, dans un réseau de communication sans connexion.
