Abstract
This application discloses a service data processing method and apparatus, to resolve a problem of low bandwidth utilization in the conventional technology. A dynamic framing method is used. When a transmission rate of an OTN data frame increases, a length of a payload area constantly increases, while a length of an overhead area does not increase. In other words, in OTN data frames at different transmission rates, lengths of overhead areas are fixed. As the transmission rates of the OTN data frames increase, lengths of payload areas constantly increase. In this way, when the rate increases, overheads do not occupy more bandwidths, thereby improving bandwidth utilization.
Claims22
A service data processing method, comprising:
- receiving, by a transmit end, service data;
- mapping, by the transmit end, the service data to a plurality of optical transport network (OTN) data frames, wherein
- the OTN data frame comprises:
- an overhead area, the overhead area is used to carry overheads of the service data, and a length of the overhead area is a fixed value and remains constant as a transmission rate of the OTN data frame changes;
- and
- a payload area, the payload area is used to carry the service data, and a length of the payload area is positively correlated with the transmission rate of the OTN data frame and increases as the transmission rate of the OTN data frame increases;
- and
- sending, by the transmit end, the plurality of OTN data frames.
A service data processing apparatus, comprising a processor and a memory, wherein
- the memory is configured to store program code;
- and
- the processor is configured to read and execute the program code stored in the memory, to implement a method that comprises:
- receiving, by a transmit end, service data;
- mapping, by the transmit end, the service data to a plurality of optical transport network (OTN) data frames, wherein
- the OTN data frame comprises:
- an overhead area, where the overhead area is used to carry overheads of the service data, and a length of the overhead area is a fixed value and remains constant as a transmission rate of the OTN data frame changes;
- and
- a payload area, where the payload area is used to carry the service data, and a length of the payload area is positively correlated with the transmission rate of the OTN data frame and increases as the transmission rate of the OTN data frame increases;
- and
- sending, by the transmit end, the plurality of OTN data frames.
