Data transmission method in flexible ethernet and device

A method implemented by an apparatus supporting Flexible Ethernet (FlexE), the method comprising:

• receiving a data block at a transmission rate of N*100 gigabits per second (Gb/s), wherein N is a positive integer greater than 1, wherein the data block is one of a plurality of data blocks from L FlexE clients, and wherein L is a positive integer;
• and
• determining, according to a rule, a FlexE client to which the data block belongs,
• wherein the rule is based on a series of data blocks received before the data block.

An apparatus supporting Flexible Ethernet (FlexE) and comprising:

• a memory configured to store instructions;
• and
• a processor coupled to the memory and configured to execute the instructions to cause the apparatus to:
• obtain data blocks from L FlexE clients, wherein L is a positive integer;
• transmit N overhead blocks in sequential order and at a transmission rate of N*100 gigabits per second (Gb/s), wherein N is a positive integer greater than 1;
• and
• transmit (R*N) data blocks in sequential order and at the transmission rate,
• wherein R is a positive integer greater than 1, and
• where the R*N data blocks are the first to (R*N)th data blocks from the data blocks.
