The ABM-3G Buffer Manager contains the following counter types
• Occupancy Counters
• Statistics Counters

Acceptance Algorithm. The thresholds are grouped by logical buffer view. For each
arriving cell, all conditions in this table are checked. Several thresholds may be
exceeded at the same time. Therefore, the table is not a truth table.
Data Sheet
Delta Hysteresis is a traffic class specific factor applied to all maximum thresholds.
The description of the hysteresis mechanism in
details.
These thresholds (four in upstream and four in downstream direction) are global
thresholds with respect to the cell buffer fill level and result in backpressure of specific
port groups of the respective UTOPIA receive interface.
These counters reflect the current buffer state and are basic elements in discard,
congestion indication and backpressure mechanisms.
These counters are used for measurements and statistics. Refer also to
