We connect our 2 machines with 2-FDDI (fiber optic) loops and 3-Token Rings
(2 @ 16 Mbps and 1 @ 4 Mbps).  The FDDI rings are probably more than enough
(I suspect -1- would be adequate).

All 5 rings have their uses, although with APPN there's a lot of automatic
selection.

The token rings were our original connection, then we added the FDDIs.  We
kept the token ring for backwards compatibility (an existing LAN runs on
the 4 Meg ring.  Our Tape Monster connects thru one of the 16s)

With our new machines we have added Ethernet connections, which will add
up-to-date networking capabilities.

No, we don't need them all.  Probably 2 token rings and 1 FDDI would handle
all of our traffic.  However, redundancy is always nice.  We've had to
replace an FDDI card at least once.

The nice thing about both Token Ring and FDDI is that they are
failure-resistant.  If an adapter fails, the circuit loops back using a
redundant signal path.  NIce to have!
