I have this vague memory of a cisco presentation that was talking 
about how the 32 Gb/s ring was constructed with the ASICs, etc. and 
there being some unusual instance where oversubscription could happen.

Certainly (as pointed out by David in another post) the backplane can 
be oversubscribed - no question.

I could be wrong (nothing unusual there) - it was just something that 
twigged in my memory.

At the end of the day, oversubscription normally isn't an issue IMO 
because (a) 99% of boxes can't push 1 Gb/s anyway and (b) even if 
they do the chances that all four (say, on an ASIC) will do it 
simultaneously is pretty low.
