A method is provided for communication between a plurality nodes organized as a ring provided with transmission resources at least one of which is a control resource dedicated to transmitting control information and associated with at least one transmission resource, said method comprising the following step executed by a node of the ring: a step of receiving information relating to a reservation of a transmission window of the transmission resource received over the associated control resource. The method further comprises, if the transmission window is reserved by another node of the ring, steps of: comparing the respective volumes of reservations of resources of the ring made by the node in question and by the other node during a reference period; and pre-empting said reservation of the transmission window as a function of the result of the comparison step.

Technique for communication between a plurality of nodes

A method of ordonnancing packets belonging to different flows comprises: a step (E) of queuing each packet in a queue associated with the flow of said packet; and for each of said queues processed cyclically, a step of sending packets contained in said queue up to a quota for said cycle; said method being characterized in that it further includes: a step (E, E) of determining the priority of said packet before said step (E, E, E) of queuing, the priority packets being, firstly, the first packets of the inactive flows, namely the flows for which no packet has been received in said cycle, and, secondly, the packets of the active flows for which the volume of packets received in the cycle is less than the quota; and a step of sending with priority in said cycle packets determined to have priority during said determination step (E, E).

Method and device for scheduling packets for routing in a network with implicit determination of packets to be treated as priority

A method is provided for configuring the service quality profile of a given flow at the access node of a packet communication network to which is connected to the gateway of a receiving user of the flow. The method includes a step where the gateway determines on its own a service quality profile to be associated with the flow, that is triggered upon reception of a packet from the access node, and a step where the service quality profile thus determined is sent to the access node. The profile is used by the access node for transmitting packets intended for the gateway and belonging to the flow in question.

Method of configuring the quality-of-service profile of a given stream at an access node of a packet communications network

Presented is a device for processing packets of flows on a network link. The device includes a scheduling module for scheduling packets in a queue in accordance with a fair queuing with priority algorithm.
