Abstract: A method for data transmission includes receiving a packet, determining a first member link in a first group of member links based on a first decision manner. If the first member link is unavailable, the method includes determining a second member link in a second group of member links based on a second decision manner, where all member links in the second group of member links are available and the first group of member links includes the second group of member links and an unavailable member link. The method includes sending the packet through the second member link.

Abstract: Embodiments of the present invention 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.
