FLOW MIGRATION METHOD AND NETWORK DEVICE

Provided in the present application are a flow migration method and a network device. The method can be applied to a device that supports multiple network cards. The method comprises: when a network device detects a load imbalance for multiple links, the network device may delete at least one flow from a link having high bandwidth occupancy and then reassign a forwarding link to the deleted flow; after at least one flow migration, balancing the load on multiple links as much as possible. Furthermore, in the present application, only some flows need to be migrated, and it is not necessary to migrate all flows on links having high bandwidth occupancy. This can prevent network lag and improve user experience. La présente demande concerne un procédé de migration de flux et un dispositif de réseau. Le procédé peut être appliqué à un dispositif qui prend en charge de multiples cartes réseau. Le procédé consiste : lorsqu'un dispositif de réseau détecte un déséquilibre de charge pour de multiples liaisons, à pouvoir
