Abstract

La présente invention concerne un procédé et un dispositif de mise en œuvre d'une agrégation dynamique de liens, ainsi qu'un support de stockage informatique. Au moyen de la présente invention, il est possible de configurer une stratégie de réglage de trafic pour obtenir des informations de paramètres de trafic sur un côté d'accès actuel, de déterminer une exigence de réglage de bande passante d'un groupe d'agrégation selon la stratégie de réglage de trafic et les informations de paramètres de trafic, puis de régler le nombre de ports membres du groupe d'agrégation selon l'exigence. Dans la présente invention, les besoins de réglage du port membre prennent en compte les informations de paramètres de trafic sur le côté d'accès actuel et s'ajustent mieux à la demande de transmission du côté d'accès actuel. Contrairement à la technique antérieure, où le fait de rejoindre ou non le groupe d'agrégation est déterminé d'après l'attribut physique du port, la présente invention peut déterminer de manière souple l'exigence de réglage de bande passante d'un groupe d'agrégation d'après les informations actuelles de paramètres de trafic sur le côté d'accès, et s'assurer que la variation dynamique du groupe d'agrégation satisfasse l'exigence sur le côté d'accès, ce qui présente manifestement une plus grande souplesse, contribue à améliorer le taux d'utilisation du port physique, réduit les coûts de maintenance et simplifie la complexité de mise en réseau, satisfaisant ainsi l'exigence d'une disposition optimisant les logiciels et améliorant la satisfaction des utilisateurs.
