8. The method of claim 1 , wherein

replacing the idle block in the data stream with the OAM block comprises: selecting the OAM block to replace the idle block in combination with at least one of a time sequence of the OAM block or a sending priority of the OAM block according to a predetermined strategy.

9. The method of claim 8 , wherein

selecting the OAM block to replace the idle block in combination with at least one of the time sequence of the OAM block or the sending priority of the OAM block according to the predetermined strategy comprises:

if a number of OAM blocks is not greater than a number of idle blocks, sequentially selecting the OAM blocks to replace the idle blocks according to time sequences.

10. The method of claim 8 , wherein

replacing the idle block with the OAM block in combination with at least one of the time sequence of the OAM block or the sending priority of the OAM block according to the predetermined strategy comprises at least one of:

if a number of the OAM blocks is greater than a number of the idle blocks, selecting the OAM blocks with high sending priorities to replace the idle blocks according to different sending priorities;

or,

if a number of the OAM blocks is greater than a number of the idle blocks and the OAM blocks to be sent have a same priority, selecting the OAM blocks to replace the idle blocks according to the time sequences.

11. The method of claim 1 , wherein

the OAM block comprises at least one of the following fields:

a type field, configured to indicate an OAM block type;

a sending priority field, configured to indicate the sending priority of the OAM block;

a sequence number field, configured to indicate the sequence number of the OAM block;

a first check field, configured to carry a first check code, the first check code being configured to check the OAM block; and

a message field, configured to carry the message content of the OAM message.

12. The method of claim 1 , wherein

acquiring the OAM block generated based on the OAM message comprises:

acquiring an OAM block generated based on a second check code and the OAM message, the second check code being generated based on a code block of an nth transmission cycle, the acquired OAM block being configured to replace an idle block of an (n+m)th transmission cycle, n being a positive integer and m being a positive integer.

13. The method of claim 12 , wherein

the OAM block comprises a first-type OAM block that is sent according to at least one of the cycle or a second-type OAM block that is sent on demand; and

acquiring the OAM block generated based on the second check code and the OAM message comprises:

acquiring the first-type OAM block generated based on the second check code and the OAM message.

14. An Operation Administration and Maintenance (OAM) message transmission method, comprising: receiving a data stream; and extracting an OAM block encapsulated according to an encapsulation format of the O block from the data stream, the OAM block being a code block replacing an original idle block in the data stream, wherein the O block comprises 8 bytes, namely zeroth to seventh bytes respectively, and only the first to third bytes and fifth to seventh bytes of the O block contain a message content of an OAM message.
