Operation, administration and maintenance OAM data transmission method and apparatus

An operation, administration and maintenance (OAM) data transmission method, comprising:

• receiving, by a second node, a second data flow of a client from at least one slot of a channel corresponding to the client, wherein the second data flow of the client comprise an OAM data block, wherein the OAM data block is a 64B/66B code block that carries OAM data, and wherein the OAM data is used for OAM detection of the client;
• detecting, by the second node, OAM of the client according to the OAM data block;
• and
• deleting, by the second node, the OAM data block from the second data flow to obtain a first data flow of the client.

An operation, administration and maintenance (OAM) data transmission apparatus, comprising:

• at least one processor;
• and
• one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to:
• obtain a first data flow of a client;
• insert an OAM data block in the first data flow of the client to obtain a second data flow of the client, wherein the OAM data block is a 64B/66B code block that carries OAM data, and wherein the OAM data is used for OAM detection of the client;
• and
• distribute the second data flow of the client to at least one slot of a channel corresponding to the client.

An operation, administration and maintenance (OAM) data transmission apparatus, comprising at least one processor and one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to perform operations comprising:

• receiving, by a second node, a second data flow of a client from at least one slot of a channel corresponding to the client, wherein the second data flow of the client comprise an OAM data block, wherein the OAM data block is a 64B/66B code block that carries OAM data, and wherein the OAM data is used for OAM detection of the client;
• detecting, by the second node, OAM of the client according to the OAM data block;
• and
• deleting, by the second node, the OAM data block from the second data flow to obtain a first data flow of the client.
