4.6.3.5 System - Network - QoS
Quality of Service (QoS) provides the means to guarantee a certain level of a specified resource to
selected traffic on an IP network. Quality can be defined as e.g. a maintained level of bandwidth,
low latency, no packet losses, etc.
• 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:
• Auto 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.
NOTES
The main benefits of a QoS-aware network can be summarized as:
- The ability to prioritize traffic and thus allow critical flows to be served before flows with lesser
priority.
