Table 21-10 Connection Parameter Descriptions
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 noncompliant 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.
VS/VD Virtual Source Virtual Destination: (See Meaning of VS/VD and Flow Control External
Segments, Figure 21-9).
