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 virtual channel setting method and the method includes: a' receiving device receives a first data packet of a first data flow from a sending device, where the first data packet includes an identifier of a first virtual channel corresponding to the first data flow; the receiving device selects a second virtual channel for the first data flow from a first virtual channel group corresponding to the first data flow, where the second virtual channel is different from the first virtual channel; and the receiving device sends an acknowledgement packet to the sending device, where the acknowledgement packet includes an identifier of the second virtual channel, and the second virtual channel is used by the sending device to update a virtual channel corresponding to the first data flow.

Abstract: This application describes a congestion control method and apparatus. In this application, a network device obtains time information of one or more congestion packets in a sent first data stream, where the one or more congestion packet carries a flag indicating a congestion notification. When the first data stream is congested, the network device obtains a first congestion notification packet based on the time information of the one or more congestion packets in the first data stream, where the first congestion notification packet notifies that a packet is congested beyond a first specified interval. The network device then sends the first congestion notification packet. According to the solutions in this application, a rate of a data stream can be prevented from being increased when the data stream is congested, and packet transmission efficiency is improved.

Abstract: Embodiments of the present disclosure relate to the field of communications technologies and disclose a packet loss detection method, an apparatus, and a system. The method includes: collecting, by a first network device according to packets sent to a second network device, statistics on a first result corresponding to each group of packets, one first result includes a quantity of packets in one group of packets and a section identifier of the group of packets, each group of packets includes multiple packets, and multiple packets are continuously sent by first network device and belong to a section corresponding to a section identifier of the group of packet; sending, by first network device, first result corresponding to each group of packets to a controller according to a preset rule, so that controller determines whether a packet in the packets sent by first network device to second network device is lost.
