2.5.4 QoS Setup
Quality of Service (QoS) refers to both a network's ability to deliver data with minimum delay, and the networking
methods used to control the use of bandwidth. Without QoS, all traffic data is equally likely to be dropped when the
network is congested. This can cause a reduction in network performance and make the network inadequate for
time-critical application such as video-on-demand.
A classifier groups traffic into data flows according to specific criteria such as the source address, destination
address, source port number, destination port number or incoming port number. For example, you can configure a
classifier to select traffic from the same protocol port (such as FTP) to form a flow.
