Abstract
The present disclosure relates to detection block sending and receiving methods, and network devices and systems. One example method includes obtaining, by a network device, an original bit block data flow, generating at least one detection block, 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.
Claims20
A detection block sending method, wherein the method comprises:
- obtaining, by a network device, an original bit block data flow of a client service;
- generating at least one detection block;
- inserting the at least one detection block into a position of at least one idle block in the original bit block data flow of the client service, wherein the at least one detection block is used for operation, administration, and maintenance (OAM) function detection of an end-to-end service forwarding path of the original bit block data flow of the client service, wherein the OAM function detection comprises at least one of connectivity check, bit interleaved parity, a remote error indication, a client service indication, synchronization, an alarm indication at a service layer, a protection switching protocol, and delay measurement, wherein the at least one detection block is a 64B/66B block, bit [0 1] of the 64B/66B block is “10”, bit [2 9] of the 64B/66B block is 0x4B, and the OAM function detection is carried in bit [10 . . . 33] of the 64B/66B block, wherein different types of detection blocks have different OAM type fields, and wherein an OAM type field is located in bit [10 . . . 33] of the 64B/66B block;
- and
- sending a bit block data flow comprising the at least one detection block.
