Traffic-shape rate <CIR in bps> <Bc in bits> <Be in Bits>
CIR The average That you want to send out (Here 2000000 bit/s)
Bc The amount of data per each Tc interval (Good value is 1/8 CIR) this
value is in bits
Be The amount of excess data allowed to be sent in the first interval (only
in the first interval).
How could i calculate Tc? Tc=Bc/Cir
So Tc = 1/8 s. So 8 interval in 1seconde.
So to calculate if we have really the Limitation of 2000000 bit/s:
Interval 1: Bc + Be = 250000 + 250000 (You add only Be in the first
interval)
Interval 2: Bc = 250000 (you are Limited to transmit Bc bit each interval
Tc)
.
.
Interval 8: Bc=250000
Total : 2250000 bit authorized in 1 second.
If you want to really limit the amount at 20000000 just put the Be to 0.
Maybe it is not clear because of my bad english but hope this help.
Yours David
