To me, this formula is really just common sense...Following the example,
if you're sending Bc (500000) per Tc (50ms), then you'll meet the CIR
(10Mbps). That leaves you with the AIR minus the CIR (45Mbps - 10Mbps =
35Mbps) of available line bandwidth. To calculate how much extra you
need to send per Tc in order to meet the max burst, you use the same
formula to determine Bc, substituting Be for Bc and the difference
between AIR & CIR for CIR.
Therefore 35000000(AIR-CIR) * .05(Tc) = 1750000 (Be)
Hope that makes sense.
HTH,
Phillip

I think it's in Odom. But that won't help you. A tattoo perhaps ;)
I will look at the Doc CD and see what I can find.
