Speaking as an admittedly biased source, the Sun Datacomm group has
managed to implement OSI (MAP/TOP) with a minimum of kernel changes
using the basic protosw, ioctl facility, and even the routing table
routines from the standard SunOS. We also have implementations of X.25,
SNA, and DECnet which all use the ifnet structure to layer different
protocol instances on top of different datalinks (HDLC, SDLC, 802.x).
As you might expect, the farther your protocol is from the TCP/IP
model, the less useful the standard networking code will be.
If your goal is XNS under Unix, it makes sense to use the 4.3
I can't really disagree with that.
As a general platform for protocol/network
development, we believe SunOS offers most of the facilities you
If your goal is general protocol/network development or cross-system
integration, the Symbolics Lisp Machine's "Generic Network System" is
probably 10x more powerful. Use UN*X to develop UN*X software,
particularly when there are no deep design issues involved. Use
something far better if there are any hard or unresolved issues to be
solved. I could easily justify my 10x claim, but this conversation
wasn't about that.
