    - Quality of service (QoS) is the overall performance of a computer network or a telephone network, the performance is seen by the users of the network.

    - Quality of service is important for the transport of traffic with special requirements.

    - Quality of service can be improved with traffic shaping techniques such as, packet prioritization, application classification and queuing at congestion points.

    - Integrated services is a flow-based QoS model design and Differentiated services is a class-based QoS model design for the Internet protocol.

    - Integrated services does not provide flexible service and scalability. It provides the Intserv framework for a small number of pre-specified service classes.

    - Differentiated services has the ability to handle different classes of traffic in different ways within the Internet. It provides the scalability.

    - Differentiated services provide the functional components. Functional components are pieces of the network architecture with which such services can be built.
