Basic VOIP shaping question



  • Hello, I want to setup some very basic traffic shaping rules.  I need my voip phone to work well 100% of the time so I want to guarantee some bandwidth.  I want p2p traffic to be fast, but not at the expense of general web browsing.

    First question, I didn't know what to enter for first page "network speeds" How do I determine this value or should I leave it blank?

    If I gaurantee a high number for voip traffic will that bandwidth still be available when the phone is not being used? My voip computer is a dedicated computer running magicjack with a static IP address. I used the IP address for shaping and used 128kbps.

    I want torrent traffic to be fast if nothing else is happening but it cannot slow down the internet or even worse, make the phone unuseable. I checked to lower the priority of p2p traffic, checked bittorrent but I use only a single port (15999) which is out of the default range so I think I will have to change that.

    Any tips would be great, thanks in advance.

    Don't leave it blank. Guess it. And correctly, or the shaper doesnot work.

    Yes, it will. Any unused bandwidth will be shared between active traffics according to the link-share bandwidth (or link-share curve, for HFSC).

    Use HFSC. Create a catch-all rule that catchs everything else into qwanp2p and qlanp2p. For VoIP create a good real-time curve. For p2p, create a good upper-limit curve.
