PXB 4330
Operational Description
4.11.5 UBR+ Connections
UBR+ connections are UBR connections with MCR. They must be setup in individual
queues with the weight factor guaranteeing the MCR.
To enhance the overall throughput, the EPD/PPD function is enabled.
4.11.6 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.
4.11.7 UBR Connections
As described in "Bandwidth Reservation" on page 4-56, 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).
