Abstract: Provided are a method and an apparatus for controlling congestion based on a generation Z (Gen-Z) interface. When a first device receives, from a second device, a second packet that is a response to a first packet transmitted to the second device, and the second packet indicates that a congestion situation occurs, the first device records priority information of a packet in a predetermined field for congestion control among fields according to the Gen-Z interface. Then, the first device transmits a third packet including priority information to the second device.
