5.2.13 QoS
QoS (Quality of Service) is a network security mechanism, and is also a technology to solve network
delay, congestion, and other problems.
For network business, QoS includes transmission bandwidth, time delay in transmission, and packet
loss of data. In network, QoS can be improved by ensuring transmission bandwidth, and reducing
time delay in transmission, packet loss rate, and delay jitter.
For DSCP (Differentiated Services Code Point), there are 64 priority degrees (063) of data packets. 0
represents the lowest priority, and 63 the highest priority. Based on the priority, the packets are
classified into different groups. Each group occupies different bandwidth and has different discard
percentage when there is congestion so as to improve service quality.
Step 1 Select Setting > Network > QoS.
