1. A method implemented by a first network device in a fully distributed model using Time-Sensitive Networking (TSN), wherein the method comprises:
receiving, from a talker device of a TSN network, a first talker attribute message requesting the first network device to deliver traffic scheduling information of a data stream, wherein the talker device is a transmitting end of the data stream;
receiving, from a listener device of the TSN network, a listener attribute message indicating that the listener device is a receiving end of the data stream;
determining, based on the first talker attribute message and the listener attribute message, the traffic scheduling information and a transmission path of the data stream, wherein the traffic scheduling information instructs generation of a gate control list for controlling a state of a first port for transmitting the data stream, and wherein the traffic scheduling information comprises time extension information indicating an extension time of currently effective traffic scheduling information before the traffic scheduling information takes effect; and
sending, to a second network device on the transmission path, a traffic scheduling message comprising the traffic scheduling information.
