4.7 Traffic
Prioritization
Quality of Service (QoS) provides a traffic prioritization mechanism that allows users to
deliver better service to certain flows. QoS can also help to alleviate congestion problems
and ensure that high priority traffic is delivered first. This section allows you to configure
Traffic Prioritization settings for each port in regards to setting priorities.
The
JetNet 4706/4706f
QoS supports 4 physical queues, weighted fair queuing (WRR)
and Strict Priority scheme, which follows 802.1p COS tag and IPv4 TOS/DiffServ
information to prioritize the traffic of your industrial network.
The following commands are explained in this section:
4.7.1 QoS Setting
4.7.2 CoS-Queue Mapping
4.7.3 DSCP-Queue Mapping
4.7.4 CLI Commands for Traffic Prioritization
4.7.1 QoS
Setting
Queue Scheduling
Use an 8,4,2,1 weighted fair queuing scheme.
This is also known as
WRR
(Weight
Round Robin)
.
JetNet will follow the 8:4:2:1 rate to process the packets in a queue from
the highest priority to the lowest. For example, the system will simultaneously process 8
packets with the highest priority in the queue, 4 packets with middle priority, 2 packets with
low priority, and 1 packet with the lowest priority.
Use a strict priority scheme.
Packets with the highest priority in the queue will always be
processed first.
