Abstract

Techniques are presented for managing firmware updates for a plurality of devices within a wireless network. Embodiments monitor network usage of the plurality of devices to collect historical usage data. An optimal window of time for updating the firmware of the plurality of devices is then determined, based on the collected historical device usage data. Embodiments flag at least one of the plurality of devices for a firmware update, based on a current firmware version of the device and a corresponding available firmware version for the device. In one embodiment, dependencies for each of the plurality of devices are considered in flagging the devices for the firmware update. The firmware of the flagged devices is updated during the determined optimal window of time.

8. The method of claim 1, further comprising:

for one or more of the flagged devices, transmitting a request to a remote server for an updated version of firmware for the flagged device; and

receiving an updated version of the firmware for the flagged device from the remote server,

wherein updating the firmware of the flagged at least one device uses the received updated version of the firmware for the flagged device.

9. A computer program product for managing firmware updates for a plurality of devices within a wireless network, comprising:

computer code that monitors network usage of the plurality of devices to collect historical device usage data;

computer code that, based on the collected historical device usage data, determines a window of time for updating firmware of the plurality of devices;

computer code that, during the determined window of time, updates the firmware of the at least one flagged device; and

a computer readable medium that stores the computer codes.

10. The computer program product of claim 9, further comprising:

computer code that queries a centralized server to determine the available firmware version for each of the plurality of devices.

11. The computer program product of claim 9, further comprising:

computer code that receives the available firmware version from each of the plurality of devices, wherein each of the plurality of devices is configured to query a respective remote server to determine the available firmware version for the device.

12. The computer program product of claim 9, wherein the computer code that flags at least one of the plurality of devices further comprises:
