S'il est déterminé, d'après un résultat statistique, qu'une probabilité d'anomalie soudaine réelle ηsudden du flux caractéristique du groupe d'agrégation de liens est supérieure à un seuil de probabilité d'anomalie soudaine λsudden, et si le débit limité d'au moins l'un des ports membres du groupe d'agrégation de liens est en sous-capacité, un débit limité d'un port membre du groupe d'agrégation de liens est ajusté. Suite à l'attribution de débits limités aux ports membres d'un groupe d'agrégation de liaisons, la solution technique susmentionnée peut, sur la base d'une situation de trafic réelle de chaque port membre, réajuster raisonnablement un débit limité d'un flux caractéristique de chaque port membre. Les ressources de bande passante de chaque port membre sont ainsi pleinement utilisées, et l'efficacité de transmission du flux caractéristique est améliorée, de même que des garanties de QoS.
