Method for Transmitting Data Stream in Flexible Ethernet, Transmitter, and Receiver

A transmitter, comprising:

• a memory comprising a program code;
• and
• a processor coupled to the memory, wherein the program code causes the processor to be configured to:
• obtain a to-be-transmitted data stream, wherein the to-be-transmitted data stream is to be transmitted using a physical connection group between a transmit end and a receive end, and wherein the physical connection group comprises N physical connections;
• allocate the to-be-transmitted data stream to the N physical connections according to a sequence of the N physical connections in the physical connection group in order to obtain N sub-streams respectively corresponding to the N physical connections;
• and
• transmit the N sub-streams using the N physical connections, wherein a sub-stream transmitted over each physical connection comprises configuration status information of each physical connection, wherein the configuration status information comprises an identifier of each physical connection and an identifier of a physical connection adjacent to each physical connection in the physical connection group, and wherein configuration status information of the N physical connections jointly indicates the sequence of the N physical connections.

A receiver, comprising:

• a memory comprising a program code;
• and
• a processor coupled to the memory, wherein the program code causes the processor to be configured to:
• receive N sub-streams using N physical connections in a physical connection group, wherein a sub-stream transmitted over each physical connection comprises configuration status information of each physical connection, wherein the configuration status information comprises an identifier of each physical connection and an identifier of a physical connection adjacent to each physical connection in the physical connection group, and wherein configuration status information of the N physical connections jointly indicates a sequence of the N physical connections;
• and
• assemble the N sub-streams according to the sequence of the N physical connections in order to restore a data stream.
