Hi there,
Does anyone have a feel for any advantages/disadvantages there might
be for using token ring rather than ethernet for fiber links connecting
routers? Here is the configuration:
A ----- B ---[Synoptics
| | Chasis]
| |
C-------D----[Synoptics
Chasis]
I'm being asked to use token ring to link routers a-b-c-d and ethernet from routers
to the Synoptics concentrators. I always prefer using ethernet wherever possible because of the simplicity/cost etc., the medium-term direction would be to use fddi between routers a-b-c-d, eventually upgrading to ATM.
I have heard that it is possible to share multiple links between routers
with OSPF2 so it would be possible to get 20, 30 or 40 Mbps aggregate throughput
between 2 adjacent routers (in theory at least), would this also be possible
with token ring? (my guess is that media shouldn't matter).
How about throughput for 16Mbps token ring vs. 10Mbps ethernet when you have
a point to point link via fiber. My guess is that ethernet may be a little better
with just 2 stations on it, but I'd be interested if anyone has done any real
