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: A packet transmission system includes a source end device that is configured to send a first packet, where the first packet carries first source routing information and a destination identifier. The first source routing information includes a port identifier of each network device on a first forwarding path, and the destination identifier indicates the destination end device. A first network device on the first forwarding path is configured to, when receiving the first packet, forward the first packet based on the first source routing information or the destination identifier, and forward the first packet based on the first source routing information based on a preference.
