Abstract: This application provides a downstream packet sending method, a downstream packet forwarding method, a downstream packet sending apparatus, and a downstream packet forwarding apparatus. The downstream packet sending method in this application includes: configuring a downstream forwarding path of a downstream packet for a terminal device; generating a source MAC address based on the downstream forwarding path, where the source MAC address is used to indicate the downstream forwarding path; and sending the downstream packet to a forwarding switch, where the downstream packet includes the source MAC address. This application can reduce costs, improve efficiency, and simplify network traffic.

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.

Abstract: Embodiments of the present invention disclose a method for processing network congestion. A first switch obtains total traffic that is received by a receiving port communicating with a third switch. The total traffic includes traffic that is occupied by a data flow sent by a second switch, and the first switch. When the first switch determines, according to the total traffic, that a sending port of the third switch is congested, the first switch determines a target port. The target port is another port that can receive the data flow and that is selected from receiving ports of the first switch. The first switch sends an adjustment message to the second switch. The adjustment message carries an identifier of the data flow and an identifier of the target port, and the adjustment message is used by the second switch to send the data flow to the target port.

Abstract: Embodiments of the present disclosure provide a packet processing method and apparatus. A first protocol identifier of a first to-be-processed packet is acquired; and first protocol rule profile information that corresponds to the first protocol identifier is acquired from a rule profile repository, where the rule profile repository stores protocol rule profile information of at least one protocol, protocol rule profile information of each protocol in the at least one protocol is associated with a protocol identifier of the protocol, the protocol rule profile information of the protocol is used to describe a method and a parameter for processing a packet, and the packet meets a standard stipulated by the protocol; and the first to-be-processed packet is processed according to the acquired first protocol rule profile information.
