Method and apparatus for bearing flexible ethernet service on optical transport network

An apparatus for bearing a flexible Ethernet service on an optical transport network (OTN), the apparatus comprising:

• a memory;
• and
• a processor coupled to the memory, the processor configured to:
• obtain a flexible Ethernet service layer that is distributed to a physical coding sublayer timeslot by means of polling, the flexible Ethernet service layer being obtained by:
• performing timeslot alignment on physical coding sublayer timeslots based on alignment marker (AM) characters in the physical coding sublayer timeslots;
• and
• deleting the AM characters in the physical coding sublayer timeslots;
• extract a flexible Ethernet service from a flexible Ethernet service layer;
• perform data division on the flexible Ethernet service to obtain a plurality of data queues comprising a first data queue and a second data queue, wherein the first data queue is identified by a first queue identifier and the second data queue is identified by a second queue identifier;
• map the first data queue into a first OTN container and the second data queue into a second OTN container, wherein the first OTN container and the second OTN container comprise either an optical channel data unit-k (ODUk) container or an optical channel data unit flexible container;
• and
• send the first OTN container and the second OTN container to an OTN.

• divide physical medium dependent (PMD) sublayer channels into a plurality of virtually concatenated containers, wherein the plurality of virtually concatenated containers comprise either an optical channel data unit-k (ODUk) virtually concatenated container or an optical channel data unit flexible virtually concatenated container;
• map the flexible Ethernet services into the plurality of virtually concatenated containers;
• combine the plurality of virtually concatenated containers into a plurality of OTN containers, wherein a quantity of the OTN containers is the same as a quantity of the PMD sublayer channels;
• and
• send the plurality of OTN containers to an OTN.
