Parameter
Description
PCR
Peak cell rate:
The cell rate which the source may never exceed
%Util
% Utilization; bandwidth allocation for: rt/nrt-VBR, CBR, UBR it’s PCR*%Util, for
ABR it’s MCR*%Util
MCR
Minimum Cell Rate:
A minimum cell rate committed for delivery by network
CDVT
Cell Delay Variation Tolerance:
Controls time scale over which the PCR is policed
FBTC (AAL5 Frame Basic
Traffic Control)
To enable the possibility of discarding the whole frame, not just one non-compliant
cell. This is used to set the Early Packet Discard bit at every node along a connection.
Note
With the BXM, FBTC means packet discard on queueing only.
