Traffic Prioritization Pages
Quality of Service (QoS) provides a traffic prioritization mechanism which allows users to deliver better
service to certain flows. QoS can also help to alleviate congestion problems and ensure high-priority traffic is
delivered first. This subsection allows you to configure Traffic Prioritization settings for each port with regard
to setting priorities. The WR7802-XT 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.
This group includes these page:

The
QoS Setting
page provides a method to queue scheduling: You can select one of the Queue Scheduling
rules.
QoS Setting
8,4,2,1 weighted fair
queuing scheme
This is also known as WRR (Weight Round Robin). The WR7802-XT
follows the 8:4:2:1 rate to process the packets in a queue from the highest
priority to the lowest. For example, the system processes 8 packets with
the highest priority in the queue, 4 with the middle priority, 2 with low
priority, and 1 with the lowest priority at the same time.
Strict priority
scheme
Packets with higher priority in the queue are always processed first, as
long as there is no packet with a higher priority.
