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.

Claim (Index 9):
The controller according to  claim 7 , the processor being configured to determine from sequentially received multiple first and second results a first result used as a first reference and a second result used as a second reference, wherein the first result used as the first reference and the second result used as the second reference correspond to a same group of packets, the controller being configured to compare the sequentially received multiple first results with the sequentially received multiple second results started from the second result used as the second reference, and when quantities of packets comprised in a first result and a second result that correspond to a same group of packets are different, determining that a packet in the packets sent by the first network device to the second network device has been lost.
