OOM: The topic here isn’t the history of packet switching or network topologies. It is the Internet. The ARPANet is the first first forerunner network of today’s internet, regardless of what network technology it utilized. NSFNet is the second forerunner network of the internet. NSFNet internetworked with the existing ARPANet. That’s when it became knowns as the internet. NSFNet had restrictions on commercial use. It was decommisioned in ’95. I’ve been involved with the network since ’91, and know this stuff without Google.
