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.
