摘要： A packet forwarding method includes a first network device receiving a first message from a second network device via a second egress port of the second network device, where the first message measures a phase difference, and where the phase difference is a phase difference between a switching time of one of a plurality of first buffers of a first egress port of the first network device and a switching time of one of a plurality of second buffers of the second egress port of the second network device with a link delay taken into consideration. The first network device determines the phase difference based on the first message. Then, the first network device schedules, based on the phase difference, a second data packet sent via the first egress port.

摘要： A traffic scheduling method includes determining, by a first network device, first traffic scheduling information and a transmission path of a first data stream based on a first talker attribute message received from a talker device and a listener attribute message received from a listener device, and then sending, by the first network device, a first traffic scheduling message to a network device on the transmission path. The first traffic scheduling message includes the first traffic scheduling information. The first traffic scheduling information indicates the network device on the transmission path to generate a gate control list. The gate control list indicates the network device on the transmission path to control, based on the gate control list, a state of a port used to transmit the first data stream.

摘要： A method for communication between controllers in TSN. A first controller receives a first packet that is sent by a second controller and that includes an identifier of a TSN domain to which the second controller belongs. The first controller determines, based on the TSN domain identifier, that the first controller and the second controller belong to a same TSN domain. The first controller sends, to the second controller, a second packet that carries user information. According to the foregoing method, communication and exchange between the controllers may be implemented, so that the controllers cooperatively configure a network device in the TSN.

摘要： A service traffic adjustment method includes a first controller obtaining a first limit value of a traffic parameter and a second limit value of the traffic parameter. The first controller obtains a target value of the traffic parameter based on the first limit value of the traffic parameter, the second limit value of the traffic parameter, and configuration information of a forwarding device through which the service flow passes. The target value of the traffic parameter meets a delay requirement of the service flow, the target value falls within a range determined based on the first limit value of the traffic parameter and the second limit value of the traffic parameter, and the first limit value is not equal to the second limit value. The first controller sends the target value of the traffic parameter.
