Abstract: The present application discloses a data processing method and apparatus. The technical solutions of the present application include: coding received data; distributing the coded data to multiple PCS lanes; and performing self-synchronizing scramble separately for multiple data streams distributed to the multiple PCS lanes, where the multiple data streams are in a one-to-one correspondence with the multiple PCS lanes. The technical solutions provided by the present application may be used to reduce occupied logical resources during a data processing process at a physical layer.

Abstract: A data processing method and apparatus are presented, which relate to the communications field and are helpful in improving flexibility and expanding application scenarios. A first physical layer coding data block flow and a second physical layer coding data block flow are received; a first data flow is obtained according to the first physical layer coding data block flow and the second physical layer coding data block flow; multiple subframe headers are generated; a second data flow is obtained according to the first data flow and the multiple subframe headers; and data blocks in the second data flow are distributed to a first physical medium dependent (PMD) sublayer circuit and to a second PMD sublayer circuit, so as to obtain a first PMD sublayer data flow and a second PMD sublayer data flow. The data processing method and apparatus are used for data processing.

Abstract: Embodiments of the present invention provide a data processing method and apparatus, including: receiving X data streams through X physical lanes of an Ethernet interface, converting the X data streams into M data streams transmitted on M virtual lanes, and performing bandwidth adjustment on each data stream of the M data streams to obtain M first data streams; receiving Y data streams through Y physical lanes of the Ethernet interface, converting the Y data streams into N data streams transmitted on N virtual lanes, and performing bandwidth adjustment on each data stream of the N data streams to obtain N second data streams. In addition, a corresponding apparatus is further provided. By using the foregoing technical solution, received data streams of different sources and different frequencies can be processed.
