It looks that Be is used only in peak rate shaping. Please read following:
Average rate shaping limits the transmission rate to the CIR. Using the CIR ensures that the average amount of traffic being sent conforms to the rate expected by the network.
Peak rate shaping configures the router to send more traffic than the CIR. To determine the peak rate, the router uses the following formula:
peak rate = CIR(1 + Be / Bc)
where:
Be is the Excess Burst size.
Bc is the Committed Burst size.
Peak rate shaping allows the router to burst higher than average rate shaping. However, using peak rate shaping, the traffic sent above the CIR (the delta) could be dropped if the network becomes congested.
Thanks,
Mike
