The present disclosure relates to data processing methods and apparatus. One example method includes obtaining a first data block from first optical path data, adding padding data and the first data block into a target information bit in a first data frame to form target data, encoding the target data to obtain a first code block, and sending the first code block.

Data processing method and related apparatus

The present disclosure discloses example method and apparatus for switching a line bandwidth of an optical transport network. One example method includes a network device switching an optical transport network (OTN) frame from a first bandwidth to a second bandwidth at a granularity of a substructure to generate a first OTN frame with the second bandwidth, where a bandwidth of the substructure is a specified value, and a difference between the first bandwidth and the second bandwidth is a multiple of the specified value. The first OTN frame with the second bandwidth is encapsulated as an encapsulated frame with the second bandwidth according to a first encapsulation protocol. The encapsulated frame with the second bandwidth is transmitted at an optical layer.

Method and apparatus for switching line bandwidth of optical transport network

The present disclosure relates to data processing methods and apparatus. One example method includes obtaining a first data block, where the first data block is a data block obtained by dividing first optical path data, adding clock simplified padding data and the first data block into a target information bit in a first data frame to form target data, where the target information bit is an information bit that is preset in the first data frame and that is used to pad optical path data, encoding the target data by using a first error correction encoding scheme to obtain a first code block that has a mapping relationship with the first data frame, where the first error correction encoding scheme matches a frame structure of the first data frame, and sending the first code block.

A full-T cross apparatus and method are provided. The full-T cross apparatus includes an input module, which includes multiple input channels; and multiple output modules, each of which includes an output channel, an output control module, and multiple data storage modules. Each of the multiple data storage modules is corresponding to each of the multiple input channels of the input module. The multiple output modules are configured to receive service data from the multiple input channels according to the output channels corresponding to the service data, and send the service data according to output time slots corresponding to the service data. In this way, the chip size is reduced to some extent, and further, the costs and power consumption of the chip are reduced.
