4.1 did not have Ethernet support from UCB. only Berknet. the original ip stack with
Ethernet support for 4.1 was done at BBN. the interface is classic unix using the open
call. similar to the MIT ChaosNet stack
CMU had a new os for the TripleDrip PERQ called Accent. it had a number of interesting
concepts such as ports.
Joy took the BBN stack and created Berkeley sockets as a reaction to Accent's
networking scheme. this would become 4.1A/B/C and eventually 4.2
btw. CMU responded to 4.2 by taking the ideas from Accent and rewriting then and
splicing them into BSD kernel to create Mach. Which lives today as the core of both
Mac OSx and iOS

Shortly thereafter in 1978, Eric Schmidt (yes,
that Eric Schmidt) wrote Berknet, which was similar to UUCP but didn't use modems, it
ran over null modem serial line interconnections. It ran on V6, V7, and the Vax.
How does that Berknet differ from the Berknet in...4.0/4.1BSD? I've seen what I
THINK was ethernet code there...but I couldn't be sure as I couldn't even
decipher the addressing scheme. ;)
I've been meaning to ask about Berknet, anyway. One of my side projects is to get
it operational.
For a few years, the Berknet link between ucbvax
(which had a modem and was on UUCP) and ingvax (which was on the ARPANET) was the gateway
between the UUCP and Usenet networks and the ARPANET.
