I don't know the details, but perhaps it is likely that 802.5's behavior beneath ARPA IP will be similar beneath ISO IP. Second, regardless of the virtues .5 might have, if most of the widely used layer 3 protocols "negate the value of many of the Token Ring's unique features", then perhaps these unique features are doomed to go to waste. I'm not knocking .5. Just your argument. This isn't comp.os.research. The real world matters here. -bc -- Bill Crews bc@halley.UUCP (512) 244-8350 ..!rutgers!cs.utexas.edu!halley!bc
