Abstract: This application provides a flow rate control method and apparatus. The flow rate control method in this application includes: receiving N explicit congestion notification packets CNPs from a first device, where the N CNPs correspond to a first data flow, and N is a natural number; and sending M CNPs to a second device based on the N CNPs, where the M CNPs correspond to the first data flow, and M is an integer greater than N. This application resolves a problem that rate increase processing is still performed on a data flow when the data flow is congested.

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 provides a path awareness method and apparatus. The method includes: A source node sends, to a destination node, a first request packet that includes an identifier of a first node, an identifier of a first data flow, and first reserved information; receives a first response packet that includes the identifier of the first data flow, the identifier of the first node, and first indication information; and obtains, based on the first response packet, information indicating that a first path passes through the first node or not. The first request packet is used to request to determine whether the first path passes through the first node, the first reserved information is used to record a result about whether the first path passes through the first node
