Abstract: The present invention discloses a packet control method and a node device, to improve reliability of a data flow in a transmission process. The method includes: After receiving a pause frame, a first node automatically applies, based on adjustment information that is of a send queue of a data flow and that is recorded in a state record set, the pause frame to all queues associated in an adjustment process of the send queue of the data flow. In this way, a packet loss problem in a data transmission process can be avoided without adjusting an XOFF/XON threshold of a receive queue and without increasing a quantity of pause frames in a network system, thereby improving reliability of the data flow in the transmission process.

Abstract: Embodiments of the present invention disclose a method for processing network congestion. A first switch obtains total traffic that is received by a receiving port communicating with a third switch. The total traffic includes traffic that is occupied by a data flow sent by a second switch, and the first switch. When the first switch determines, according to the total traffic, that a sending port of the third switch is congested, the first switch determines a target port. The target port is another port that can receive the data flow and that is selected from receiving ports of the first switch. The first switch sends an adjustment message to the second switch. The adjustment message carries an identifier of the data flow and an identifier of the target port, and the adjustment message is used by the second switch to send the data flow to the target port.

Abstract: Example packet control methods and apparatus are described. One example method includes detecting, by a network node, a packet in a packet flow causing a congestion from an upstream node. The network node reduces a scheduling priority of the packet in the packet flow and generates a congestion isolation message, where the congestion isolation message includes description information of the packet flow. The congestion isolation message is sent to the upstream node to instruct the upstream node to reduce the scheduling priority of the packet in the packet flow.
