Quality of service guarantees are important if the network capacity isinsufficient, especially for real-time streaming multimedia applications. Quality can be defined as, for instance,a maintained level of bit rate, low latency, no packet dropping, etc.The following are the main benefits of a QoS-aware network:• The ability to prioritize traffic and guarantee a certain level of performance to the data flow.• The ability to control the amount of bandwidth each application may use, and thus provide higher reliabilityand stability on the network.Requirements for QoSTo utilize QoS in a network environment, the following requirements must be met:• All network switches and routers in the network must include support for QoS.• The network video devices used in the network must be QoS-enabled.QoS modelsCoS (the VLAN 802.1p model)IEEE802.1p defines a QoS model at OSI Layer 2 (Data Link Layer), which is called CoS, Class of Service.
