btw: the addressing scheme in Berknet is pretty simple. it's mupltiplexing an 9600
baud rs232c connection point to point without full connectivity (like uucp). although
IIRC the sender did not have to specify the path. Berknet figured it out for you - but I
might be confusing a different network scheme from those days. there were so many

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
