Service data processing method and apparatus

A service data processing method, comprising:

• receiving an optical transport network (OTN) frame that is mapped with an intermediate frame carrying at least one of first service data or second service data,
• wherein the first service data has a bandwidth less than a first threshold, and the second service data has a bandwidth not less than the first threshold, the first threshold is greater than or equal to 50 megabits per second (Mbps) and less than or equal to 200 Mbps,
• wherein the first service data is timeslot-based multiplexed in the intermedia frame by a first timeslot-based multiplexing and a second timeslot-based multiplexing, the second service data is single-level timeslot-based multiplexed in the intermedia frame by the second timeslot-based multiplexing, the first timeslot-based multiplexing has a first bit width and a first bandwidth, and the second timeslot-based multiplexing has a second bitwidth and a second bandwidth, the second bit width is an integer multiple of the first bit width, and the second bandwidth is an integer multiple of the first bandwidth;
• recovering the intermediate frame from the OTN frame;
• obtaining the at least one of the first service data or the second service data from the intermediate frame.

A service data processing apparatus, comprising:

• a processor, and
• a non-transitory memory storing programing instructions that, when executed by the processor, cause the service data processing apparatus to perform:
• receiving service data;
• performing a first processing manner or a second processing manner on the service data based on a bandwidth of the service data and a first threshold, to obtain an intermediate frame that carries the service data;
• mapping the intermediate frame to an optical transport network (OTN) frame;
• and
• sending the OTN frame;
• wherein:
• when the bandwidth of the service data is less than the first threshold, the first processing manner is performed, the first processing manner comprising:
• performing first timeslot-based multiplexing on the service data based on a first bit width and a first bandwidth, to obtain a first data stream of the first bit width, converting the first data stream into a second data stream of a second bit width, performing second timeslot-based multiplexing on the second data stream based on the second bit width and a second bandwidth, to obtain the intermediate frame;
• when the bandwidth of the service data is not less than the first threshold, the second processing manner is performed, the second processing manner comprising:
• performing single-level timeslot-based multiplexing on the service data based on the second bit width and the second bandwidth, to obtain the intermediate frame;
• and
• wherein
• the first threshold is greater than or equal to 50 megabits per second (Mbps) and less than or equal to 200 Mbps, the second bit width is an integer multiple of the first bit width, and the second bandwidth is an integer multiple of the first bandwidth.
