Abstract: In a network congestion handling method, a first network device determines a target port, where the target port is an egress port that is in a pre-congestion state or a congestion state. The first network device sends a first notification to at least one second network device. The at least one second network device is capable of sending, through at least two forwarding paths, a data flow to a host corresponding to the target port. The first notification includes information of a network device to which the target port belongs and information of the target port. The first notification can enable the at least one second network device to perform an operation of avoiding network congestion. The network congestion handling method can effectively alleviate network congestion and improve network bandwidth utilization.

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.
