Each time you start the ARN, it completes a process to load these files.

The software image contains a group of executable files that support the
protocols that the network requires. The ARN uses the software image called

Nortel Networks ships the executable and default configuration files on a

a file over the network is called network booting, or netbooting. Getting a file
from the router file system, stored in flash memory, is local booting.
