Policy-based Quality of Service (QoS) is a feature of ExtremeWare XOS 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.
