In a method of fair queue servicing at a queuing point in a multi-service class packet switched network, incoming packets are received in buffers and outgoing packets are scheduled by a weighted fair queue scheduler. Real-time information of buffer usage along with the minimum bandwidth requirement is used to dynamically modify the weights of the weighted fair queue scheduler.

La présente invention concerne un procédé de desserte équitable de files d'attente en un point de mise en file d'attente dans un réseau à commutation de paquets de classe multi-service. Selon ce procédé, les paquets en entrées sont pris en charge dans des tampons, les paquets en sortie étant planifiés par un planificateur de file d'attente équitable pondérée. Les modifications dynamiques des pondérations du planificateur de file d'attente équitable pondérée se font sur la base des informations en temps réel d'utilisation du tampon ainsi que sur la base de la largeur de bande minimale requise.
