CB-Shaping can be done in two different ways: Shape average and Shape Peak.
Shape average limits the transmission rate to CIR, whereas, with Shape peak
the router can send more traffic than CIR.
The formula is:
Peak Rate = CIR (1+Be/Bc) and remember by default Be and the Bc are set to
8k
With Shape Peak you are allowed to burst higher than CIR but remember that
the excess traffic has the potential of being dropped if the network is
congested. Typically used if the network has more bandwidth available and
the app that is being used can handle packet loss.
