Download method and system based on management data input/output interface

摘要

The disclosure provides a download method and system based on a Management Data Input/Output (MDIO) interface, wherein the download method based on the MDIO interface comprises: a master device informing a slave device of using the MDIO interface to start downloading data packets in batches; the master device transmitting data packets in batches to the slave device by using an MDIO frame, wherein the MDIO frame comprises: a data packet address field and/or a data packet serial number field, wherein the data packet address field is used to indicate a relative address of one data packet in the slave device, and the data packet serial number field is used to indicate a location of said one data packet in multiple data packets; the slave device judging that a received data packet is a last data packet of a current batch transmission from the master device, and finishing a current batch download. The invention enables the master device and the slave device to perform the batch data download effectively, and solves the problem in the related art that large batch data transmission cannot be performed for download based on the MDIO interface.
