Abstract

Upgrading a peripheral device in a network device includes sending an upgrade package to the network device over a computer network and automatically upgrading the internal software of the peripheral device using the upgrade package.

Claims

1. A method comprising:

receiving, at a network device, an upgrade package over a computer network sent from a client device, the upgrade package including a flash erase file containing null data and upgrade software;

determining upgrade information for a peripheral device installed in the network device, the upgrade information comprising a type and version of the peripheral device and an upgrade process for the peripheral device;

determining if the update package is compatible with the peripheral device based on the upgrade information; and

automatically upgrading internal software of the peripheral device if the upgrade package is compatible with the peripheral device by appending contents of the flash erase file to a packet header, the packet header containing instructions for the peripheral device for overwriting contents of software in the peripheral device with the appended contents, and by transferring the packet header and the upgrade software to the peripheral device by a connection.

2. The method of claim 1 including recognizing the received package as an upgrade package based on information contained in the upgrade package.

3. The method of claim 1 including recognizing the received package based on a filename extension associated with the package.

4. The method of claim 1 wherein automatically upgrading the internal software includes:

opening a communications channel to the peripheral device; and

updating the peripheral device with contents of the upgrade package.

5. The method of claim 4 wherein upgrading the peripheral device includes:

setting the peripheral device to an upgrade mode;

parsing contents of the upgrade package into a format suitable for the peripheral device; and

transferring the parsed contents to the peripheral device.

6. The method of claim 5 wherein setting the peripheral device to an upgrade mode includes issuing a command to the peripheral device.

7. The method of claim 1 including sending a message indicating success or failure of the upgrade to a source of the upgrade package.

27. The method of claim 1 wherein upgrading the internal software of the peripheral device occurs independently of a particular type of operating system on the client device.

8. A system comprising:

a computer network;

a network device coupled to the network; and

a peripheral device installed within the network device;

wherein the network device comprises a processor configured to;

receive over the network an upgrade package that includes a flash erase file containing null data and upgrade software to update the peripheral device;

determine upgrade information for a peripheral device installed in the network device, the upgrade information comprising a type and version of the peripheral device and an upgrade process for the peripheral device;

determine if the update package is compatible with the peripheral device based on the upgrade information;

append contents of the flash erase file to a packet header if the peripheral device is compatible with the upgrade information, the packet header containing instructions for the peripheral device to overwrite contents of software in the peripheral device with the appended contents; and

transfer the packet header and the upgrade software to the peripheral device by a connection to automatically upgrade the peripheral device if the contents of the flash erase file are appended to the packet header.

9. The system of claim 8 wherein the processor is configured to upgrade internal software of the peripheral device with the package.

10. The system of claim 8 wherein the network device is configured to recognize the received package as an upgrade package based on information contained in the package.

11. The system of claim 8 wherein the network device is configured to recognize the received package as an upgrade package based on a filename extension associated with the package.

12. The system of claim 8 wherein the processor is configured to:

open a communications channel to the peripheral device; and

upgrade the peripheral device with contents of the upgrade package.

13. The system of claim 12 wherein the processor is configured to:

set the peripheral device to an upgrade mode;

parse contents of the upgrade package into a format suitable for the peripheral device; and

transfer the parsed contents to the peripheral device.

14. The system of claim 13 wherein the processor is configured to set the peripheral device to the upgrade mode by issuing a command to the peripheral device.

15. The system of claim 8 wherein the processor is configured to send a message indicating success or failure of the upgrade to a source of the upgrade package.

16. An article comprising a computer-readable medium that stores computer-executable instructions for causing a computer system to:

recognize a received package as an upgrade package intended for a peripheral device installed in a network device, the upgrade package including a flash erase file containing null data and upgrade software;

determine upgrade information for a peripheral device installed in the network device, the upgrade information comprising a type and version of the peripheral device and an upgrade process for the peripheral device;

determine if the update package is compatible with the peripheral device based on the upgrade information;

append contents of the flash erase file to a packet header if the peripheral device is compatible with the upgrade information, the packet header containing instructions for the peripheral device to overwrite contents of software in the peripheral device with the appended contents; and

transfer the packet header a;

id the upgrade software to the peripheral device by a connection to automatically

upgrade internal software in the peripheral device if the contents of the flash erase file rare appended to the packet header.

17. The article of claim 16 including instructions for causing the computer system to recognize the received package as an upgrade package based on information contained in the package.

18. The article of claim 16 including instructions for causing the computer system to:

open a communications channel to the peripheral device; and

upgrade the peripheral device with contents of the upgrade package.

19. The article of claim 18 including instructions for causing the computer system to:

set the peripheral device to an upgrade mode;

parse contents of the upgrade package into a format suitable for the peripheral device; and

transfer the parsed contents to the peripheral device.

20. The article of claim 19 including instructions for causing the computer system to issue a command to the peripheral device in order to set the peripheral device to the upgrade mode.

21. The article of claim 16 including instructions for causing the computer system to send a message indicating success or failure of the upgrade.

22. An apparatus comprising:

a port for coupling the apparatus to a network;

a peripheral device installed in the apparatus; and

a processor;

wherein the processor is configured to;

receive an upgrade package through the port, the upgrade package including a flash erase file containing null data and upgrade software;
