USING QOS TO PRIORITIZE VOIP TRAFFIC

Traffic priority is a way of ensuring that specific applications or sub networks are guaranteed a certain
amount of the uplink bandwidth at all times. Traffic priorities only come into play when the network is using
all of the pre-configured bandwidth on the uplink.
For VoIP environments, network latency can be a big issue that can be caused by network congestions due
to file transfer operations for example. Hence, making audio or video calls very hard to deal with where a
delay can make the communication impossible, on the other hand, having a little delay on your downloaded
file for example is not very critical to the network.
And since VoIP signaling or voice/video communications are very critical to most Enterprises in the age of
Unified Communication, and does not require a very large bandwidth, is it very required to give these types
of services a special treatment.

QoS Configuration using IP Address

In this section, we will show how to prioritize traffic for a specific IP within GWN7000 Network.

Figure 3: Prioritizing by IP Address

In above example figure, we will prioritize all traffic coming from GVC3200's IP address (Video Conferencing
System) regardless of the service or port used on the conferencing System.
