Novell is an implementation of Xerox XNS cleverly done to fit into a PC
and still leave room to get some work done.  XNS runs at levels 2 & 3
of the OSI reference model.

>3Com   = XNS

3Com makes various products that run at various levels of the model.
Are you referring to 3+Open?

IBM TR = IEEE 802.5 is at the physical level (level 1) of the reference
model.  You can run any protocol you want at levels 2-up, including Novell.

Novell = IPX

3Com   = XNS

IBM TR = ???

Can anyone fill in the blank???

Thanks many,

Some additional info.... Yes IBM TR uses 802.5 at the physical level.
Netware, and most other protocols that I have seen use LLC 802.2 and
some well known SAP hung off of 802.2.

I think however the question you are asking is what is the "common"
name of the protocol that runs on IBM LAN equipment.  It is commonly
referred to as NETBEUI and provides 802.2 LLC class 1 and class 2 services.
In addition, there is an IBM NETBIOS protocol which makes use of the
LLC services.

Actually, the IBM NETBIOS protocol is called NETBEUI; it stands for
NETBios Extended User Interface. That was the first available protocol
from IBM running on top of 802.2 LLC. It is an extension of the Sytek
proprietary protocols running on the original PC/Net adapter which
introduced the world to NetBios. IBM really wants the world to adopt
LU6.2 as their transport-and-above-layers protocol suite. That's
available from IBM as APPC and it runs on top of 802.2 LLC also.
