I wonder if we're getting tied into CIR when we should be having a closer look at BIR and PIR?
BIR?
CIR = Committed information rate EIR = Excess information rate PIR = Peak information rate (CIR + EIR)
BIR is new to me - can you elaborate?
BIR = EIR Stands for Burst Information Rate. relationship is: PIR = CIR+EIR
