摘要
This application provides a detection block sending and receiving method, and a network device and system. The detection block sending method includes: obtaining, by a network device, an original bit block data flow; generating at least one detection block, and inserting the at least one detection block into a position of at least one idle block in the original bit block data flow; and sending a bit block data flow including the at least one detection block. In this application, a bandwidth resource of an idle block in a bit block data flow is occupied for sending a detection block, thereby resolving a problem of a service bit block loss.
