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.

Abstract: A buffer configuration method and a switching device are disclosed, to ensure no packet loss, and belongs to the field of network technologies. The method includes: sending, by a first switching device, a first measurement frame to a second switching device; receiving, by the first switching device, a second measurement frame sent by the second switching device, where the second measurement frame is generated based on the first measurement frame; determining, by the first switching device, a buffer configuration parameter based on the first measurement frame and the second measurement frame; and setting, by the first switching device, a local buffer based on the configuration parameter. The present disclosure is used to automatically configure a buffer of a switching device, thereby reducing required buffer space without packet loss.
