13.1.2.1 Firmware Upgrade
Service providers require the ability to update the device's firmware in the field (e.g. in case
of maintenance releases or releases that support new required features). The process is
required to be automatic, allowing mass update, which is robust and fail-safe.
The device's firmware is stored on the non-volatile flash memory. The device's flash
memory is capable of storing a recovery firmware that ensures a fail-safe operation (even if
the user unplugs the power during the firmware burning process).
The device's firmware can be upgraded using one of the following mechanisms:

The new firmware can be "pushed" (uploaded) to the device, using the device's Web
interface

The new firmware can be "pulled" (downloaded) by the device from a remote HTTP,
FTP, or TFTP server
The device has two areas in flash memory for storing the firmware image. One area is
active, while the other is "burned" during the upgrade process.
If the upgrade process was successful, the new image is set as "active", while the other
area will be used for the next upgrade. If upgrade is not successful, the one that is still
active remains valid.
The remote firmware download process can be triggered by one of the following:

The device checks for a new firmware upon MP-264 restart

The device periodically checks for a new firmware

Manual trigger using CLI, TR-069 or Web
Note:
Version 4.4.0
Unless forced, the device downloads and upgrades to the new firmware only if
its version number is higher than the firmware version currently running on the
device. The version number is not taken from the image file name, but from the
header of the image file.
