    QoS是什么?为什么需要QoS?


    正确答案:服务质量(Quality of Service,QoS)是一种抽象概念,用于说明网络服务的“好坏”程度。在开放系统互连OSI参考模型中,有一组QoS参数,描述传送速率和可靠性等特性。但这些参数大多作用于较低协议层,某些QoS参数是为传送时间无关的数据而设置的,因此多媒体通信网络需要定义合适的QoS。

    The DiffServ model relies on a fairly simple mechanism to provide QoS over a wide range of equipment.

    D

    RSVP enables the DiffServ model to provide end-to-end QoS.

    E

    The DiffServ model is more scalable than the IntServ model.

    F

    The flow-based approach of the DiffServ model is ideal for large scalable implementations such as the public Internet.
