Type
The type of traffic control option used
for ATM cells. The traffic descriptor
combination specifies which traffic
parameters are used for traffic control,
determines 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 appendix for a
detailed description of the
values for this field.
Default:
Best-effort
This traffic descriptor allows the system
to attempt to send all cells in a "best
effort" fashion, without specifying traf-
fic parameters, similar to the
AQue-
Man
™
algorithm.
1B-NT-0+1
This traffic descriptor uses the parame-
ters one bucket, no tagging, cell loss pri-
ority (CLP)=0+1 cells (high and low
priority).
2B-NT-0+1-0+1 This traffic descriptor uses the parame-
ters two buckets, no tagging, CLP=0+1
cells (high and low priority) for bucket
1, and CLP=0+1 cells (high and low pri-
ority) for bucket 2.
2B-NT-0+1-0
This traffic descriptor uses the parame-
ters two buckets, no tagging, CLP=0+1
cells (high and low priority) for bucket
1, and CLP=0 cells (high priority) for
bucket 2.
2B-T-0+1-0
This traffic descriptor uses the parame-
ters two buckets, CLP=0+1 cells (high
and low priority) for bucket 1, and tag-
ging 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, similar to the
AQueMan
™
algorithm.
