Title (EN) METHODS AND SYSTEMS FOR NETWORK CONGESTION MANAGEMENT
(FR) PROCÉDÉS ET SYSTÈMES DE GESTION D'ENCOMBREMENT DE RÉSEAU
Abstract:
(EN) A method for managing network congestion is provided. The method comprises: receiving, at a receiver, a packet comprising a timestamp provided by a first clock of a sender; deriving, by the receiver, a latency value based at least in part on the timestamp provided by the first clock and a receipt time provided by a second clock of the receiver; determining a latency change by comparing the latency value with a previous latency value; and determining a state of network congestion based at least in part on the latency change.
(FR) L'invention concerne un procédé de gestion d'encombrement de réseau. Le procédé comprend : la réception, au niveau d'un récepteur, d'un paquet comprenant un horodatage fourni par une première horloge d'un expéditeur ; la déduction, par le récepteur, d'une valeur de latence basée au moins en partie sur l'horodatage fourni par la première horloge et un temps de réception fourni par une seconde horloge du récepteur ; la détermination d'un changement de latence par comparaison de la valeur de latence avec une valeur de latence précédente ; et la détermination d'un état d'encombrement de réseau sur la base, au moins en partie, du changement de latence.
