  • 第2题：

    Which two of these are differences between traffic policing and traffic shaping？（）

    • A、with traffic shaping，a router stores excess traffic in packet buffers until bandwidth is available again
    • B、with policing you can tune the buffer usage for traffic exceeding the specified CIR
    • C、with shaping you can tune the buffer usage for traffic exceeding the specified CIR
    • D、shaping should only be applied for ingress traffic，policing only for egress

  • 第3题：

    what is the advantage of policing opposite to shaping？


    正确答案: （1）policing does not require extra memory， and it does not impose variable delay.But shaping requires memory for buffering excess traffic， which creates variable delay and jitter；
    （2）Policing can re-mark traffic， but traffic shaping does not re-mark traffic.
    （3）Policing can be applied to the inbound and outbound traffic （with respect to an interface）， but traffic shaping applies only to outbound traffic.
    1.policing dost not require extra memory.
    2.policing can remark traffic.
    3.policing can be used to inbound and outbound traffic.shaping is used only in outbound.
