Patent

CA 2387101

Methods, apparatus and program products for controlling a flow of a plurality of packets in a computer network are disclosed. The computer network includes a device defining a queue. The methods, apparatus and program products include determining a queue level for the queue and determining an offered rate of the plurality of packets to the queue. They also include controlling a transmission fraction of the plurality of packets to or from the queue, based on the queue level, the offered rate and a previous value of the transmission fraction so that the transmission fraction and the queue level are critically damped if the queue level is between at least a first queue level and a second queue level. Several embodiments are disclosed in which various techniques are used to determine the manner of the control.

L'invention concerne des procédés, un appareil et un programme destinés à réguler un flux de plusieurs paquets dans un réseau informatique. Le réseau informatique comprend un dispositif définissant une file d'attente. Les procédés relatifs à l'appareil et au produit sous forme de programme consistent à déterminer un niveau de file d'attente pour la file d'attente et à déterminer un débit proposé des paquets dans la file d'attente, ainsi qu'à réguler une fraction de transmission des paquets en provenance ou à destination de la file d'attente et une valeur précédente de la fraction de transmission, de manière à ce que la fraction de transmission et le niveau de file d'attente soient amortis de façon critique si le niveau de la file d'attente se situe entre au moins un premier niveau de file d'attente et un deuxième niveau de file d'attente. L'invention couvre plusieurs modes de réalisation dans lesquels on utilise diverses techniques pour déterminer la façon d'effectuer la régulation.
