Configuring QoS Settings

Go to Setup Network Setup Qos.
Quality of Service (QoS) is a network security mechanism. It fixes problems with network
delays and jams. For network service, the quality of service includes the transmission
bandwidth, delay, and packet loss, for example. Through QoS, you can guarantee the
transmission bandwidth, reduce the delay, reduce the loss of data packets, and enhance the
transmission quality with packet prioritization.
To utilize QoS in a network environment, the following requirements must be met:
•
All network switches and routers in the network must include support for QoS.
•
The network video devices used in the network must be QoS-enabled.
CoS
CoS refers to Class of Service. It indicates the frame priority level from 0 (lowest) to 7
(highest). The priority is set up on the network switches, which then use different queuing
disciplines to forward the packets.

Figure 5-10 QoS

Enter the VLAN ID of your switch (0~4095) and choose the priority for each application (0~7).
If you assign Video the highest level, the switch will handle video packets first.

QoS/DSCP
Routers at each network node classify packets according to their DSCP ((Differentiated
Services Codepoint) value and give them a particular forwarding treatment; for example, how
much bandwidth to reserve for it.

A VLAN Switch (802.1p) is required. Web browsing may fail if
the CoS setting is incorrect.
The Class of Service technologies do not guarantee a level of
service in terms of bandwidth and delivery time; they offer a
"best-effort." Users can think of CoS as "coarsely-grained"
traffic control and QoS as "finely-grained" traffic control.
Although CoS is simple to manage, it lacks scalability and
does not offer end-to-end guarantees since it is based on L2
protocol.
