Cnfrm Type
(displayed on
the
Traffic
Parameters B
to A
panel only)
The type of traffic control option used for ATM cells.
The traffic descriptor combination specifies which
traffic parameters are used for traffic control, deter-
mines the number and type of cells that are admitted
into a congested queue, and determines whether
high-priority cells are tagged as low-priority cells
when traffic exceeds the traffic parameter thresholds.
Note:
See the section, “ATM Traffic Descriptors,” in
the Reference Appendix for a detailed description of
the values for this field, including representative
examples.
Default:
Best-effort
This traffic descriptor allows the system to attempt to
send all cells in a "best effort" fashion, without speci-
fying traffic parameters, similar to the AQueMan
algorithm.
One-bucket-
notag-0plus1
This traffic descriptor uses the parameters one bucket,
no tagging, cell loss priority (CLP)=0+1 cells (high
and low priority).
Two-bucket-
notag-0plus1-
0plus1
This traffic descriptor uses the parameters two buck-
ets, no tagging, CLP=0+1 cells (high and low priority)
for bucket 1, and CLP=0+1 cells (high and low prior-
ity) for bucket 2.
Two-bucket-
notag-0plus1
This traffic descriptor uses the parameters two buck-
ets, no tagging, CLP=0+1 cells (high and low priority)
for bucket 1, and CLP=0 cells (high priority) for
bucket 2.
Two-bucket-tag-
0plus1
This traffic descriptor uses the parameters two buck-
ets, CLP=0+1 cells (high and low priority) for bucket
1, and tagging for CLP=0 cells (high priority) in
bucket 2.
Best-effort-tag
This traffic descriptor allows the system to tag all
CLP=0 (high priority) cells to change them to CLP=1
(low priority) cells during congestion, and then
attempt to send all cells in a "best effort" fashion,
without specifying any other traffic parameters, simi-
lar to the AQueMan algorithm.
Traffic Flow
Duplex
(default)
SimplexA2B
Direction of the flow of data traffic in this connection.
Note:
When you select
SimplexA2B
, the fields in
the
Traffic Parameters B to A
panel do not display.
