Abstract: Embodiments provide a packet forwarding method and a network device, which are applicable to a system that includes a source node, a destination node, a first device, and a second device, where L1, L2, L3 and L4 are established, and the packet forwarding method includes: receiving, by the second device through a universal tunnel, a packet to be sent to a destination node, where the packet carries service data and one of identifiers of the L1, the L2, the L3, and the L4; according to the identifier carried in the packet, querying a preconfigured logical channel mapping in the second device, determining that a forwarding channel is the L4, and sending the service data in the packet to the destination node through the L4. By using the technical solutions, the number of ICB PWs can be reduced.

Abstract: This application discloses a network congestion control method and a network device, and relates to the field of communication technologies, to improve continuity and completion of a packet in a transmission process of a Transmission Control Protocol (TCP) flow. In this application, when pre-congestion (that is, congestion may occur) occurs in a forwarding direction of the TCP flow, a forwarding device reduces a value of a receive window (RWND) field in an acknowledge (ACK) packet, to reduce a sending rate of a transmit end for a packet in the TCP flow or delay sending of a packet by a transmit end. This relieves buffer pressure of the forwarding device, reduces a packet loss, and improves the continuity and the completion of the packet in the transmission process of the TCP flow.
