    Hi Rene,
    When you are talking about customer transmitting ("shaping " part of the lesson ), I believe you are talking about uploading ? .
    What if a customer downloading How we can survive from ISP dropping the traffic ?

    Thanks

  3. Hello Sims

    When talking about shaping on the customer side, it can be applied for both uploading and downloading. When implementing on the customer side, the interface can be configured for shaping since it has memory allocated for both an Input queue and Output queue.

    So this can be done for both uploading and downloading.

    I hope this has been helpful!

  4. Hi, Rene, thanks for the guidelines about video traffic as below:

     One-way delay: 200 – 400 ms.
     Jitter:30 – 50 ms.
     Loss: 0.1% - 1 %

    I was wondering can it also work on surveillance cameras ?

    So that I can do basic calculations about how many bandwidth required of building a surveillance system, thank you.

  5. Hello Wallace

    The one way delay for video that Rene mentions is usually for videoconferencing or video telephony where there is a two way conversation taking place and any longer delays would become bothersome. For video that has only one direction, like broadcast video or surveillance cameras, delay is not that important. So there is more leeway for the delay, however, jitter and packet loss will still have an affect on the quality of the video being sent.

    I hope this has been helpful!
