ROMMON uses TFTP to download an image and launch it. TFTP does not address network issues such 
as latency or error recovery. It does implement a limited packet integrity check so that packets arriving 
in sequence with the correct integrity value have an extremely low probability of error. But TFTP does 
not offer pipelining so the total transfer time is equal to the number of packets to be transferred times 
the network average RTT. Because of this limitation, we recommend that the TFTP server be located on
