Abstract
Embodiments of this application provide a service data processing method. The method includes: receiving service data, performing encapsulation, rate adaptation, and timeslot multiplexing on the service data by code block to obtain an intermediate frame, mapping the intermediate frame to an OTN frame, and sending the OTN frame. A size of the code block is a plurality of bytes, and the code block includes information indicating a code block type. If the code block is an overhead code block or a rate adaptation code block, the code block further includes information indicating a timeslot multiplexing layer at which the code block is located.
Claims20
A method, comprising:
- receiving service data;
- performing encapsulation, rate matching, and timeslot multiplexing on the service data by code block to obtain an intermediate frame that carries the service data;
- mapping the intermediate frame that carries the service data to an optical transport network (OTN) frame;
- and
- sending the OTN frame, wherein a size of at least one code block is a size of a plurality of bytes, the at least one code block comprises first information, the first information indicates a code block type of the at least one code block, and wherein when the code block type of the at least one code block is an overhead code block or a rate adaptation code block, the at least one code block further comprises second information, and the second information indicates a timeslot multiplexing layer at which the at least one code block is located.
A method, comprising:
- receiving an optical transport network (OTN) frame, wherein the OTN frame carries an intermediate frame that carries service data, and the intermediate frame is obtained by performing encapsulation, rate adaptation, and timeslot multiplexing on the service data by code block;
- and
- performing timeslot demultiplexing, rate adaptation code block deletion, and decapsulation by code block to obtain the service data from the OTN frame, wherein a size of at least one code block is a size of a plurality of bytes, the at least one code block comprises first information, and the first information indicates a code block type of the at least one code block;
- and
- wherein when the code block type of the at least one code block is an overhead code block or a rate adaptation code block, the at least one code block further comprises second information, and the second information indicates a timeslot multiplexing layer at which the at least one code block is located.
An apparatus, comprising:
- a receiver, configured to receive service data;
- at least one processor, configured to:
- perform encapsulation, rate adaptation, and timeslot multiplexing on the service data by code block to obtain an intermediate frame that carries the service data, and
- map the intermediate frame that carries the service data to an optical transport network (OTN) frame;
- and
- a transmitter, configured to send the OTN frame, wherein a size of at least one code block is a size of a plurality of bytes, the at least one code block comprises first information, the first information indicates a code block type of the at least one code block, and
- wherein when the code block type of the at least one code block is an overhead code block or a rate adaptation code block, the at least one code block further comprises second information, and the second information indicates a timeslot multiplexing layer at which the at least one code block is located.
