2.7 QoS

2.7.1 QoS Introduction

The S1526 supports basic QoS function. With proper port
priority settings, when network congestion occurs, the system
first drops packets on ports with lower priorities to ensure the
transmission of packets on ports with higher priorities. The
switch supports 4 queues, with queue 0 having the lowest
priority and queue 3 having the highest priority. The queue
scheduling algorithm supported by the switch is Weighted
Round Robin (WRR).

2.7.2 QoS Configuration

Click [QoS] on the menu bar to enter the [QoS
Configuration] page, as shown in
relation of queues and priorities, and the weight, whose value
can range from 1 to 15. Click <Apply> on the right to complete
QoS configuration.
For example, as shown in
priorities 0 and 1 in queue 0, packets with priorities 2 and 3 in
queue 1, packets with priorities 4 and 5 in queue 2, and packets
with priorities 6 and 7 in queue 3. Set the weight values for
queues 0, 1, 2, 3 to 1, 2, 4, 8 respectively. With this setting, if
packets in queues 0, 1, 2, 3 congest on a port, the port will send
the packets according to a traffic ratio of 1:2:4:8.
