10 Quality of Service Configuration
10.1 Brief overview of the quality of service section
PMP320 provides different quality of service (QOS) settings per the 802.16e
specification e.g UGS, rtPS, nrtPS and BE. User can choose the appropriate QoS
profile based on the application needs. It is recommended that each QoS profile is
created with specific Maximum Information Rate (MIR) and Committed
Information Rate (CIR) as dictated by the application needs. The PMP320 system
can support several QoS profiles (e.g. 256) with different combinations of QoS
types, MIR and CIR.
Each PMP320AP serves several CPEs under given sector. Each CPE could have
multiple service flows in both UL and DL direction. Each flow is associated with a
given QoS profile which is configured based on end user need. One CPE could have
multiple flows to serve different applications simultaneously. To differentiate
multiple flows under a single CPE, PMP320 uses classification profiles. These
classification profiles are associated with specific service flows. Different
applications, both over UL and DL can send their data using classifications which
helps CPE and AP to associate data traffic to specific service flow with QoS type.
PMP320 supports source/destination IP address and TOS/DSCP (Diff Serve Code
Point) classifications.
10.2 QoS profile creation
Create/Add/Update/Delete additional QoS profiles using AP GUI, "Configuration"
"QoS Profile". AP will have QoS profile number 0 and 1 created by default
which is fixed. One can add different QoS profile as needed.
To add a new QoS profile, provide the new index, name if needed, selection of
HARQ, # Retries, security enabled or disable, DSCP marking disable or enable,
appropriate DSCP mark value (e.g TOS value) if DSCP Marking is enabled.By
default, HARQ is enabled with retries "0", Security and DSCP Marking is disabled.
Recommended configuration for the DL flow is HARQ enabled with retry "0" and
for the UL flow is HARQ disabled.
