Abstract: This application provides a virtual channel setting method and the method includes: a' receiving device receives a first data packet of a first data flow from a sending device, where the first data packet includes an identifier of a first virtual channel corresponding to the first data flow; the receiving device selects a second virtual channel for the first data flow from a first virtual channel group corresponding to the first data flow, where the second virtual channel is different from the first virtual channel; and the receiving device sends an acknowledgement packet to the sending device, where the acknowledgement packet includes an identifier of the second virtual channel, and the second virtual channel is used by the sending device to update a virtual channel corresponding to the first data flow.

Abstract: This application provides a method and an apparatus for determining a port orientation. The method includes: A first network device receives, through a first port, a protocol data unit PDU sent by a second network device. The first network device determines, based on the PDU, that the first port is an upstream port or a downstream port. In this embodiment of this application, the first network device may determine, based on the PDU sent by the second network device, whether the first port is the upstream port or the downstream port, to provide a basis for subsequently helping an SDN controller reduce load.
