Abstract

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.

First claim

What is claimed is:

1. A download method based on a Management Data Input/Output (MDIO) interface, comprising:
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; and
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;
wherein the step of the master device informing the slave device of using the MDIO interface to start downloading the data packets in batches comprises:
the master device informing, through an MDIO protocol command, the slave device of using the MDIO interface to start downloading the data packets in batches, wherein the MDIO protocol command comprises download register information, wherein the download register information comprises serial numbers of the data packets transmitted in batches by the master device to the slave device;
the step of the slave device judging that a received data packet is the last data packet in the data packets transmitted in batches by the master device comprises:
the slave device judging according to a serial number that the received data packet is the last data packet in the data packets transmitted in batches by the master device.

2. The method according to claim 1 , wherein the MDIO frame uses an idle field of a set number of bits to replace a preamble field.

3. The method according to claim 2 , wherein the step of the master device informing the slave device of using the MDIO interface to start downloading the data packets in batches comprises:
the master device informing, through an MDIO protocol command, the slave device of using the MDIO interface to start downloading the data packets in batches, wherein the MDIO protocol command comprises download register information, wherein the download register information comprises serial numbers of the data packets transmitted in batches by the master device to the slave device;
the step of the slave device judging that a received data packet is the last data packet in the data packets transmitted in batches by the master device comprises:
the slave device judging according to a serial number that the received data packet is the last data packet in the data packets transmitted in batches by the master device.

4. The method according to claim 2 , wherein the step of the slave device judging that a received data packet is the last data packet of the current batch transmission from the master device comprises:
the slave device receiving one MDIO frame transmitted by the master device, parsing out a data packet from the MDIO frame, and storing data of the data packet in the slave device according to an address indicated by the data packet address field or according to a serial number indicated by the data packet serial number field; and
the slave device judging that the stored data packet is the last data packet of the current batch transmission from the master device.

5. The method according to claim 2 , further comprising:
during a process that the master device transmits the data packets in batches to the slave device by using the MDIO frame, the master device reading download status register information of the slave device through an MDIO protocol command;
the master device judging, according to the download status register information, whether the slave device receives a previous group of data packets normally;
if so, starting downloading a new group of data packets in batches; otherwise, forcing the slave device to stop a batch download.

6. The method according to claim 2 , further comprising:
during a process that the master device transmits the data packets in batches to the slave device by using the MDIO frame, if an abnormality of the master device or the slave device occurs and a batch download of the data packets is not stopped,
the master device setting a value of the data packet address field or the data packet serial number field of the MDIO frame to indicate the slave device to stop the batch download of the data packets.

7. The method according to claim 2 , wherein before the step of the master device informing the slave device of using the MDIO interface to start downloading the data packets in batches, the method further comprises:
the master device setting a length of the MDIO frame according to hardware conditions of the slave device.

8. The method according to claim 1 , wherein the step of the slave device judging that a received data packet is the last data packet of the current batch transmission from the master device comprises:
the slave device receiving one MDIO frame transmitted by the master device, parsing out a data packet from the MDIO frame, and storing data of the data packet in the slave device according to an address indicated by the data packet address field or according to a serial number indicated by the data packet serial number field; and
the slave device judging that the stored data packet is the last data packet of the current batch transmission from the master device.

9. The method according to claim 1 , further comprising:
during a process that the master device transmits the data packets in batches to the slave device by using the MDIO frame, if an abnormality of the master device or the slave device occurs and a batch download of the data packets is not stopped,
the master device setting a value of the data packet address field or the data packet serial number field of the MDIO frame to indicate the slave device to stop the batch download of the data packets.

10. The method according to claim 1 , wherein before the step of the master device informing the slave device of using the MDIO interface to start downloading the data packets in batches, the method further comprises:
the master device setting a length of the MDIO frame according to hardware conditions of the slave device.

11. The method according to claim 1 , further comprising:
during a process that the master device transmits the data packets in batches to the slave device by using the MDIO frame, the master device reading download status register information of the slave device through an MDIO protocol command;
the master device judging, according to the download status register information, whether the slave device receives a previous group of data packets normally;
if so, starting downloading a new group of data packets in batches; otherwise, forcing the slave device to stop a batch download.

12. A download system based on an MDIO interface, comprising: a master device and a slave device, wherein
the master device comprises:
an informing module, configured to inform the slave device of using the MDIO interface to start downloading data packets in batches; and
a transmitting module, configured to transmit the 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 comprises
