The way we did it was that the backbone was designed at three times port
speed, so no matter if everyone ordered zero CIR, the backbone could still
handle it.
They claimed to give a price break for zero CIR, but the pricing wasnt much
different. Just some marketing fluff.

But, as we know the service providers sell the PVc' s based on the CIR. The
cost is related to that.
Have they chneged thier policy from some time.
One more question is
what will hapen if every customer strat ordering ZERO CIR ?
The network might have less congstion i guess.!
Any thoughts.

The only exception would be if you kept all of your traffic in your
provider's cloud, and they said that zero CIR is no problem. I used to work
for Ameritech, and in our LATA, our frame switches didn't even look at the
DE bits (at least that is what our frame engineers said). They had
over-engineered the backbone to handle three times the amount of traffic
that the edge could provide, to protect against a single device failure
causing them any problem. So in this case, having a zero CIR would not cause
any problem.
But if you left our LATA and crossed someone else's cloud, your traffic was
not safe.

I wouldn't recommend zero CIR unless you want to save some money and
the traffic your sending is minimal and not especially important. Like
Yigit alludes to, all packets are DE with zero CIR. We generally only
provide zero CIR if customers request it or they originate from some
other carrier that is zero CIR. Funny things happen when they CIRs
don't match.
