Abstract: 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.

Abstract: This application provides a Example communication methods and apparatus, to improve packet scalability are described. In one example, a method includes: A first node receives a first packet from a second node, and parses the first packet. The first packet includes multicast routing information of the second node, and the first node is a child node of the second node in a multicast tree. A multicast routing identifier of a node is used by a non-leaf child node of the node in the multicast tree to determine multicast routing information of the non-leaf child node, and multicast routing information of a node includes a multicast routing identifier of the node and multicast routing information of a non-leaf child node of the node in the multicast tree.

Abstract: A packet processing method is disclosed. The method includes: A first network device receives a first packet from a network at a first moment, where the first packet is a 1st packet in a first burst of a first data flow, the first burst is one of a plurality of bursts included in the first data flow received by the first network device, the first burst includes one or more packets, and the first network device is a first-hop network device that processes one or more packets included in the first data flow. The first network device determines, based on the first moment, a first target queue from a plurality of queues included in a first queuing system of the first network device.

Abstract: This application provides data packet scheduling methods and apparatuses. 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.

Abstract: 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.
