Abstract: Embodiments of the present disclosure disclose a Clos network load balancing method and apparatus. In certain embodiments, the method includes receiving, by a first switch, a first packet and determining, by the first switch, a third switch. The third switch is a switch in a second group of switches. The method includes performing, by the first switch, tunnel encapsulation on the first packet, a destination Internet Protocol (IP) address in a tunnel-encapsulated IP header being an IP address of a second switch. The method includes performing, by the first switch, Internet Protocol in Internet Protocol (IP-in-IP) encapsulation on the tunnel-encapsulated first packet and sending, by the first switch, the IP-in-IP encapsulated first packet.

Abstract: 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.

Abstract: A multicast packet sending method includes a first node that obtains a first multicast packet including multicast routing information of a second node, and sends the first multicast packet to the second node. The second node is a non-leaf subnode of the first node in a multicast tree. Multicast routing information of a node includes a multicast routing identifier of the node and multicast routing information of a non-leaf subnode of the node in the multicast tree. A multicast routing identifier of a node is used by the node to determine a subnode of the node in the multicast tree. The multicast routing information is embedded in the multicast packet, and multicast routing information of a tree recursive structure included in the multicast packet can describe packet forwarding information of the multicast tree or a subtree of the multicast tree.
