EBS Test (Excess Burst Size)
Burst frame signals corresponding to the specified EBS value are sent. When transmission is
complete, frame signal transmission is stopped for a given time. Then, traffic is resumed at the
summed rate of the committed information rate (CIR) and excess information rate (EIR).
When colors (green and yellow) are assigned to frames, green frames are sent at the CIR rate and
yellow frames at the EIR rate.
When the transmission at the CIR+EIR rate for a given time is complete, frame signal transmission
is stopped for a given time.
This operation is repeated to measure the parameters (FL, FTD, FDV) of burst frame traffic for the
specified time (T seconds).
