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 (0–63) 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.
