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.
This switch 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.

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.
