Claim:
1. A data forwarding method, comprising: receiving, by a current device, a basic frame sent by a first device according to a first transmission rate, wherein the basic frame comprises a control word and at least one data block; when received basic frames form a super frame, extracting, by the current device, a control word in each basic frame in sequence, and storing in a buffer area; converting, by the current device, each control word in the buffer area in sequence according to a second transmission rate supported by a second device, so as to obtain a corresponding target control word; migrating, by the current device, each data block in each basic frame in sequence according to prestored data migration information, so as to obtain a target basic frame corresponding to each basic frame, wherein the data migration information comprises migration information of each basic frame, and the migration information of each basic frame comprises: the number of data blocks, an identifier of each data block, a length of an area on which each data block resides, a start address of each data block before the migrating, and a start address of each data block after the migrating, which are comprised in the basic frame; and inserting, by the current device, each target control word into each target basic frame in sequence, and sending each target basic frame to the second device according to the second transmission rate.
