∇ QoS
Quality of Service (QoS) provides the means to guarantee a certain level of a specified re-
source 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:
1. The ability to prioritize traffic and thus allow critical flows to be served before flows with
lesser priority.
2. Greater reliability in the network, due 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 traffics IP
header. When the marked traffic reaches a network router or switch, the DSCP value
in the IP header tells 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; enter a value for each type of traffic used:
– Live Stream DSCP
– Event/Alarm DSCP
– Management DSCP
• Automatic Traffic Control
Check the box to enable automatic traffic control. Set a limitation on user network
resources by designating the maximum bandwidth. Select either the Maximum band-
width or Automatic framerate radio button.
– Maximum bandwidth: When 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.
