What this tab is for
On this tab, you can turn on the Quality of Service (QoS) feature which can help solve
network delay and network congestion by configuring the priority of data sending.
Differentiated Services Code Point (DSCP)
Differentiated Services (DiffServ, or DS) is a method for adding QoS to IP networks. In routed
networks, critical network traffic such as video and audio streams, which require a relatively
uninterrupted flow of data, can get blocked due to other traffic. DiffServ can be used to
classify network traffic and give precedence - that is, low-latency, guaranteed service, to
high-priority traffic.
Each stream has a DSCP (Differentiated Services Code Point) field in the IP header. Routers
will identify the network service type in the DSCP field and provide the appropriate level of
service.
To turn on QoS
1
In Video/Audio DSCP, Event/Alarm DSCP and Management DSCP, type the DSCP value.
The valid range of the DSCP value is 0~63. The higher the DSCP value, the higher the
priority.
2
Click Save.
A reboot is required for the settings to take effect.
Note: Make sure that you enable the QoS function of your network device (such as a
router).
