Quality of Service

Quality of Service. Overview. Why QoS? When QoS? One model: Integrated services Contrast to Differentiated Services (more modern; more practical; not covered). What is QoS?. Providing guarantees (or rough bounds) on various network properties: Available bandwidth for flows Delay bounds
