		Peer Firmware Sharing may also aid in firmware

		scenarios over bandwidth-limited WAN links.
		When enabled, it allows the phone to discover
		similar phones on the subnet that are requesting the
		files that make up the firmware image, and to
		automatically assemble transfer hierarchies on a
		per-file basis. The individual files making up the
		firmware image are retrieved from the TFTP
		server by only the root phone in the hierarchy, and
		are then rapidly transferred down the transfer
		hierarchy to the other phones on the subnet using
		TCP connections.
