ABM-3G
PXF 4333 V1.1
Operational Description
To enhance the overall throughput, the EPD/PPD function is enabled.
4.2.7.5 GFR Connections
GFR Connections are setup like UBR+ connections with a Guaranteed Rate in individual
queues, with the weight factor guaranteeing the rate for the high-priority packets. The
threshold for the discard for low-priority packets must be set accordingly.
4.2.7.6 UBR Connections
As described in âBandwidth Reservationâ on Page 116, one queue per Scheduler is
reserved for UBR connections with the smallest weight assigned. All UBR connections
share this queue. EPD/PPD can be enabled as the relevant parameters are stored per
connection (LCI table).
4.2.7.7 Generic Service Classes
Besides the standard ATM Forum service categories, other generic service classes can
be flexibly supported by the ABM-3G.
Quality of service differentiation in terms of absolute and relative guarantees can be
achieved for any traffic stream that is segmentable into the ABM-3G cell format.
