Abstract
A fault detection method and device is disclosed. The method includes obtaining, by an optical transport network (OTN) device, a first OTN frame. The first OTN frame includes a plurality of payload areas. Each payload area includes payload check information and payload data. The method further includes performing fault detection, according to the payload check information, of payload data of a payload area in which the payload check information is located. The first OTN frame is divided into a plurality of payload areas, and corresponding payload check information is carried in each payload area.
Claims20
A fault detection method, comprising:
- obtaining, by an optical transport network (OTN) device, a first OTN frame, wherein the first OTN frame comprises a plurality of payload areas and each payload area carries payload data and payload check information;
- and
- for each of the payload area of the plurality of payload areas, upon transmission of the payload data, performing fault detection to determine a faulty working trail, by the OTN device, according to the payload check information, wherein performing the fault detection comprises checking the payload data for each of the payload area of the plurality of payload areas according to the payload check information located in the same payload area as the payload data being checked.
A fault detection device, comprising:
- a processor;
- and
- a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions to:
- obtain a first Optical Transport Network (OTN) frame, wherein the first OTN frame comprises a plurality of payload areas, wherein each payload area carries payload data and payload check information configured to be used to determine a faulty working trail;
- and
- for each of the payload area of the plurality of payload areas, upon transmission of the payload data, perform fault detection to determine a faulty working trail, according to the payload check information, wherein performing the fault detection comprises checking the payload data for each of the payload area of the plurality of payload areas according to the payload check information located in the same payload area as the payload data being checked.
A method, comprising:
- receiving, by a first optical transport network (OTN) device, a first payload area of a plurality of payload areas in a first OTN frame that is transmitted by a second OTN device in a network with the first OTN device, wherein each payload area in the first OTN frame carries payload data and payload check information that relates to checking payload data of the payload area;
- and
- performing fault detection to determine a faulty working trail on the first payload area that is received, according to the payload check information in the first payload area before receiving, by the first OTN device, another payload area of the plurality of payload areas, performing the fault detection comprises checking the payload data in the first payload area according to the payload check information located in the first payload area;
- wherein payload data in each payload area comprises a portion of service data that is carried in the first OTN frame sent by the second OTN device to the first OTN device.
