QoS
You can solve problems such as network delay and congestion with this QoS (Quality of
Service). It helps to assure bandwidth, and reduce transmission delay, packet loss rate, and
delay jitter to improve service quality.
For DSCP (Differentiated Services Code Point), it has 64 degrees (0–63) of priority for packets;
0 is the lowest and 63 is the highest. It can select different queues and the bandwidth of each
queue according to the priority. When the network is congested, bandwidth of different queues
will be discarded with different ratios so as to guarantee service quality.
Select Setting > Network > QoS .
The QoS interface is displayed. See Figure 4-34.
