7) 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,

nd no packet losses. a

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:
