[net.lan] protocol implementations in/on UNIX

mostek@laidbak.UUCP (Jim Mostek) (07/26/85)

     I'd like to hear from anybody who's written device drivers that
talk to protocol implementations (like TCP/IP) running on front end 
processors.  I'm also interested in drivers that actually implement 
the protocols themselves.  In particular:
   - How difficult were these drivers to write and debug compared to,
     say, a tty device driver?
   - How big were they, again compared to something like a tty driver?
   - How difficult was the driver implementation compared to doing it
     under some other operating system?
   - And, finally, how does the complexity of a driver that implements
     the protocol compare with one that just talks to a front end
     processor running the protocol?

Thanks.

Please *post* any information you have about this, including pointers
on how to do it, et all. We're just starting in implement our own
Kiewit Stream Protocol under 4.2 BSD and would like to get a good idea
of what we're letting ourselves in for. If you've done it, what sort of
experience did you have before you started, how many people worked on
it, for how long, etc, etc, etc. Many thanks, in advance.
