QoS management is the collection of mechanisms that control how traffic is prioritized and handled during congestion

All these QoS tools rely on traffic classification:the better the classification, the better the QoS

To make the process as manageable as possible, QoS deployments need to take into account:QoS needs of the organizationCurrent network architectureApplications used by the staffTraffic running over the networkQoS capabilities available in the network devices
