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:
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:
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 bandwidth 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.
– Priority:
When the maximum bandwidth is exceeded, the data to be reduced is prioritized.
When the settings are complete, click
Save
button to save the settings, or click
Reset
button to
clear all of the information you entered without saving it.
