A traffic shaping method and a traffic shaping apparatus are disclosed. The method includes: A packet marking apparatus receives a first packet; the packet marking apparatus determines an enqueuing queue of the first packet; and the packet marking apparatus marks a queue identifier of the first packet as a queue identifier of the enqueuing queue of the first packet, and then sends the queue identifier of the first packet to a packet output apparatus, where the packet output apparatus is configured to send, based on the queue identifier of the first packet, the first packet to a corresponding queue for outputting. Therefore, the packet output time after traffic shaping can be determined.

One method includes: A first network device receives, at a first moment, a data packet from a second network device in a network, the first network device determines a first reference moment based on the first moment and time information carried in the data packet, the first network device determines, based on the first reference moment, a target queue from a plurality of queues included in a first queue system and adds the data packet to the target queue, and the first network device processes the target queue according to a scheduling rule of the plurality of queues.

Data packet scheduling method and related apparatus

This application provides a mapping relationship updating method, applied to deterministic networking. The method includes: A first device sequentially obtains a first packet and a second packet that are sent by a second device; the first device determines a first time difference between a time at which the first packet is received and a time at which the second packet is received; and if the first device determines that the first time difference is not within a preset range, the first device updates a period-based mapping relationship.

Mapping relationship updating method and apparatus

This application discloses a packet transmission method, an apparatus, a device, and a readable storage medium, and relates to the field of communication technologies. The method applied to a second network device includes: First, a first packet sent by a first network device is received, and then a second packet, a first dwell time period, and a second dwell time period are obtained based on the first packet. Then, a time difference between the second dwell time period and the first dwell time period is determined. Then, a third dwell time period and a fourth dwell time period are determined, to encapsulate the third dwell time period, the fourth dwell time period, and the second packet to obtain a third packet.

Packet transmission method, apparatus, device, and readable storage medium

A packet transmission method and apparatus, and a system. The method includes: after receiving a first packet, a first device determines, based on a condition met by a first number carried in the first packet, a manner of sending the first packet. When the first number of the first packet meets a first condition, a second device determines a second cycle label corresponding to a first cycle label and sends the first packet to a third device in a cycle corresponding to the second cycle label. When the first number of the first packet meets a second condition, the second device determines a third cycle label corresponding to the first cycle label and sends the first packet to the third device in a cycle corresponding to the third cycle label.

The method includes: receiving, by a first network device, a first unicast join message sent by a second network device, where the first unicast join message is used to request to join a multicast group, a source address of the first unicast join message is an address of the second network device, and a destination address of the first unicast join message is a multicast source address or a rendezvous point (RP) address; and establishing, by the first network device, a tunnel from the first network device to the second network device based on the first unicast join message. The multicast service implementation method and apparatus in embodiments of this application help improve availability of a multicast service.

Method and apparatus for multicast service availability

The present disclosure relates to resource reservation methods. One example method includes receiving, by a controller, a resource reservation request that is of a communication session and that is sent by a sending device, where the resource reservation request carries resource requirement information, obtaining, by the controller based on the resource reservation request, identification information of a network device through which data transmission of the communication session to be performed between the sending device and a receiving device passes, and a resource index of the network device, sending, by the controller, the resource requirement information and the resource index to the network device based on the identification information, where the resource requirement information and the resource index are used to instruct the network device to configure a resource for the communication session, and sending, by the controller, the identification information and the resource index to the sending device.

Resource reservation method and related device

This application discloses a multicast forwarding method and a multicast router. The method includes: listening to, by a first multicast router, a plurality of unicast packets passing through the first multicast router, and determining a set of unicast packets that are from a same upstream multicast router and that belong to a same unicast stream; when determining that destination addresses of at least two unicast packets in the unicast packet set are different, sending, by the first multicast router, a prune message to the upstream multicast router; and sending, by the first multicast router, the received unicast packets with the multicast identifier to the destination devices corresponding to the destination address group. The method is used to provide a new multicast method, so as to implement multicast functions of some routers in an existing unicast network architecture.
