Frame Loss Measurement Calculation
Figure 4-199: Loss Measurement Calculation
In dual ended frame loss measurement, both ends calculate the Frame loss.
Since the time for reading the counters in MEP-A is done before the readout in MEP-B, there is an
inaccuracy in the calculation. This can be averaged out by averaging over some time intervals.
Also note that this loss measurement is valid for low loss ratios (<20%). If the loss ratio is too
high, LMM/LMR frames are lost and the calculation will be incorrect
