 QoS
Quality of Service (QoS) provides the means to guarantee a certain level of a specified resource to
selected traffic on a network. Quality can be defined as a maintained level of bandwidth, low latency,
and no packet losses.
The main benefits of a QoS-aware network are:
- The ability to prioritize traffic and thus allow critical flows to be served before flows with lesser
priority.
- Greater reliability in the network, thanks to the control of the amount of bandwidth an application
may use, and thus control over bandwidth races between applications.

DSCP Settings
For each type of network traffic supported by your network video product, enter a DSCP
(Differentiated Services Code Point) value. This value is used to mark the traffic's IP header.
When the marked traffic reaches a network router or switch, the DSCP value in the IP header tell
the router or switch which type of treatment to apply to this type of traffic, for example, how
much bandwidth to reserve for it. Note that DSCP values can be entered in decimal or hex form,
but saved values are always shown in decimal.
The following types of traffic are marked:
- Live Stream DSCP:
- Event/Alarm DSCP:
- Management DSCP:
• Automatic Traffic Control
Set a limitation on user network resources by designating the maximum bandwidth.
- Maximum bandwidth: In case of sharing other network programs or equipment, it is
possible to set a limitation on the maximum bandwidth in the unit of Mbit/s or kbit/s.
- Auto frame rate: Selected if not influenced by a network-related program or equipment
without a limitation on the network bandwidth.
