Method for transmitting data in flexible ethernet and device

A method implemented by a first network device for transmitting data, comprising:

• sending, to a second network device according to a first client calendar, first data comprising a plurality of data blocks, wherein the first client calendar comprises a correspondence between a client and a first timeslot set, and wherein the first timeslot set comprises a first timeslot;
• receiving, from the second network device, an overhead frame, wherein the overhead frame indicates that the first timeslot is damaged, and wherein the first timeslot is damaged when a quantity of error data blocks that correspond to the first timeslot meets a condition;
• sending, to the second network device, a second client calendar, wherein the second client calendar comprises a correspondence between the client and a second timeslot set;
• and
• sending, to the second network device, second data using the second client calendar.

A first network device, comprising:

• a physical layer transceiver that:
• receives, from a second network device and according to a first client calendar, first data comprising a plurality of data blocks, wherein the first client calendar comprises a correspondence between a client and a first timeslot set, and wherein the first timeslot set comprises a first timeslot;
• and
• sends, to the second network device, an overhead frame, wherein the overhead frame indicates that the first timeslot is damaged;
• a FlexE shim circuit coupled to the physical layer transceiver and that:
• receives the first data from the physical layer transceiver;
• and
• sends an overhead frame comprising the timeslot damage notification to the physical layer transceiver;
• and
• a media access controller coupled to the FlexE shim circuit and the physical layer transceiver, wherein the media access controller:
• determines an error data block in the data blocks;
• and
• determines, based on the error data block, that the first timeslot is damaged when a quantity of error data blocks that correspond to the first timeslot meets a condition, wherein the physical layer transceiver further:
• receives a second client calendar from the second network device, wherein the second client calendar comprises a correspondence between the client and a second timeslot set;
• and
• receives, from the second network device, second data using the second client calendar,
• wherein the FlexE shim circuit receives the second data from the physical layer transceiver.

A first network device, comprising:

• a physical layer transceiver;
• and
• a FlexE shim circuit coupled to the physical layer transceiver, wherein the FlexE shim circuit:
• sends, to a second network device using the physical layer transceiver and according to a first client calendar, first data that comprises a plurality of data blocks, wherein the first client calendar comprises a correspondence between a client and a first timeslot set, and wherein the first timeslot set comprises a first timeslot;
• receives, from the second network device using the physical layer transceiver, an overhead frame, wherein the overhead frame indicates that a first timeslot in the first timeslot set is damaged, and wherein the first timeslot is damaged when a quantity of error data blocks that correspond to the first timeslot meets a condition;
• sends, to the second network device using the physical layer transceiver, a second client calendar, wherein the second client calendar comprises a correspondence between the client and a second timeslot set;
• and
• sends, to the second network device using the physical layer transceiver, second data using the second client calendar.
