    Class based QoS :

    - Differentiated services are class-based QoS model designed for Internet protocol.

    - Class bases QoS does not provide scalability and flexible service differentiation.

    - The Intserv framework provides a small number of pre-sepcified service classes.

    Flow based QoS :

    - Integrated services are flow based QoS model designed for Internet protocol.

    - Flow based QoS provides scalability and flexible service differentiation.

    - It does not define service classes.
