[comp.dcom.lans] What is TP4?

albers@ka3ovk.uucp (Jon Albers) (07/12/90)

I have just gotten finished convincing some people here that networking our
mini's together via TCP/IP is a _Good Thing To Do_ (tm), and I come to find
out that within the next few years, the IRS has decided to migrate to a
standard called "TP4".  What is it?  Is is an 'improved' TCP/IP protocol?
Will the migration from an ethernet/TCP/ip network to TP4 likly involve new
hardware or just new software?

TP4 is a one of a class of protocols being developed for use in
the ISO/OSI world.  These are TP0 through TP4.  Each has different
features along the lines of connection oriented, or non, reliable
delivery, or not.  TP4 in particular is the one which most closely
matches that required by the IP level of TCP/IP, specifically
connectionless and unreliable delivery.

It will likely just involve new software.  For instance, the group I
work in at TWG is developing, and has announced, a line of OSI software
based on ISODE (5.0 now, 6.0 very soon). 

If you wander over to comp.protocols.iso.all you'll find discussion
on these protocols.

If you're interested in detailed documentation, that is available
from OmniCom Inc.  They are in Falls Church Va, but I don't know where
or what the phone number is.
