Embodiments of this application provide a communication method, a communications device, and a storage medium, to process an invalid block in a data stream. In embodiments of this application, N first block streams are obtained, where N is a positive integer. When there is an invalid block in the N first block streams, the invalid block in the N first block streams is converted into a target block, to obtain a to-be-sent block stream. Then, the to-be-sent block stream is sent. Because the invalid block in the block stream is checked and converted into the target block, an error that occurs in service data at a receive end and that is caused by the invalid block can be reduced.

Communication method, communications device, and storage medium

A method of data processing is applied to a communications device including a first sublayer. A physical sublayer is added above a physical coding sublayer (PCS) of a physical layer, and the physical sublayer is connected to media independent interfaces (xMIIs) with different Ethernet rates. Data signals from different media access control clients (MAC) are interleaved using the physical sublayer. Then, a tx_cmd command is used to instruct the PCS to correspondingly encode an xMII signal. Finally, an encoded xMII signal is sent through a port. According to this method, an encoding function of the PCS may continue to be used, to decouple interleaving from encoding and perform the interleaving through an xMII interface. In this case, port channelization can be implemented for ports with multiple rates, and transmission of a high-priority service is ensured when there is an excessively large quantity of service flows in a transmission process.
