Service processing method and apparatus and device

A service processing method, wherein the method comprises:

• receiving an optical transport network (OTN) transmission frame, wherein the OTN transmission frame is used to carry encoded service data, and the encoded service data comprises control information and service data;
• obtaining the control information and check information of the control information from an overhead area of the OTN transmission frame;
• checking the control information based on the check information;
• obtaining, based on a check result being correct, service data information from a payload area of the OTN transmission frame;
• reassembling the control information and the service data information to obtain the encoded service data;
• and
• decoding the encoded service data to obtain the service data,
• wherein the control information comprises a code block type indication, and when the code block type indication indicates that a 257b code block is a control code block, the encoded service data further comprises a first code block pattern indication, and the first code block pattern indication indicates a pattern of a 66b code block comprised in a code block in which the first code block pattern indication is located.

An optical transport network (OTN) device, wherein the device comprises:

• an optical transceiver configured to:
• receive an OTN transmission frame sent by a processor;
• and
• send the OTN transmission frame, or receive the OTN transmission frame and send the OTN transmission frame to the processor;
• and
• the processor configured to:
• obtain service data;
• encode the service data to obtain encoded service data, wherein the encoded service data comprises control information and service data information;
• map the control information to an overhead area of an OTN transmission frame;
• check the control information to obtain check information;
• map the check information to the overhead area of the OTN transmission frame;
• map the service data information to a payload area of the OTN transmission frame;
• and
• send the OTN transmission frame carrying the encoded service data,
• wherein the control information comprises a code block type indication, and when the code block type indication indicates that a 257b code block is a control code block, the encoded service data further comprises a first code block pattern indication, and the first code block pattern indication indicates a pattern of a 66b code block comprised in a code block in which the first code block pattern indication is located.
