Policy-based Quality of Service (QoS) is a feature of ExtremeWare and the Extreme switch architecture
that allows you to specify different service levels for traffic traversing the switch. Policy-based QoS is an
effective control mechanism for networks that have heterogeneous traffic patterns. Using Policy-based
QoS, you can specify the service level that a particular traffic type receives.
