Abstract: The present application discloses a congestion control method and an apparatus. The method includes: receiving, by a root node network element, a first link notification message; determining, based on the link status information of the first link, that the first link is congested; determining an identifier of a first leaf node network element based on a correspondence between an identifier of the first port and the identifier of the first leaf node network element; determining a service queue of the first leaf node network element based on a correspondence between the identifier of the first leaf node network element and an identifier of the service queue of the first leaf node network element; and lowering output bandwidth of the service queue of the first leaf node network element.

Abstract: A queue scheduling method includes querying, by a routing device according to a network service, a preset correspondence table after receiving the network service sent by a user and obtaining a storage queue corresponding to the network service, where the correspondence table includes correspondence between the network service and the storage queue. The method further includes storing data of the network service in the storage queue corresponding to the network service and allocating a scheduler to the storage queue, so that the data in the storage queue can be sent according to scheduling of the scheduler.

Abstract: Embodiments of the present invention disclose a packet forwarding method and apparatus. The method includes: receiving, by a first scheduler, a target packet; sending the target packet to a destination physical egress port corresponding to the egress port information, and increasing, according to the queue identifier, a queue length of a virtual queue corresponding to the queue identifier by the packet length; sending update information to a second scheduler, where the update information includes that the queue length of the virtual queue is increased by the packet length; and decreasing the queue length of the virtual queue by the packet length according to a bandwidth scheduling result that is corresponding to the update information and sent by the second scheduler. In this way, even if back pressure appears in the destination physical egress port corresponding to the target packet, that the first scheduler sends the target packet is not affected.
