Guarantee speed to a ip address



  • Can i guarantee speed(dl and up) to a specific ip address in lan and how?



  • Yes. There are several ways to do it.

    What kind of traffic is the IP in question using?

    Do you want to guarantee a percentage of the pipe or a specific bps value?

    Do you want to set a max speed or just a min?

    It using RDP protocol.
    I want to guarantee minimum speed.



  • you can set minimum values in HFSC that will never be shared even when idle.

    You can use dummynet and set weights that will ensure the IP gets at least x% of the pipe. But if everything else isn't using dummynet as well then it wouldn't work.



  • HFSC always shares bandwidth. What you can do is set and upper limit. HFSC is all about setting the minimum. If you want a queue to have at least some amount of bandwidth, set it to that amount. If you want a queue to never have more than some amount of bandwidth, add that. You must be explicit. Never forget to set the interface bandwidth.



  • HFSC minimum values if set is unshared



  • @belt9:

    HFSC minimum values if set is unshared

    Kinda but not really. If the (minimum) bandwidth is unused, other queues can use it. Perhaps you are confusing real-time's hard-limit on bandwidth allocation? Even if real-time is completely allocated (80% configured interface bitrate?), when said bandwidth is unused, the bandwidth can be used by link-share.

    Harvy66 is correct and makes a good point about HFSC's upper-limit.

    HFSC minimum values if set is unshared

    The minimum value shares idle bandwidth, the only bandwidth worth sharing. If I set the minimum to 1Mb on my 150Mb connection and nothing else is using bandwidth, it will get 150Mb/s. If all other queues start using bandwidth, that queue will suddenly drop down to 1Mb/s as expected.



  • I stand corrected!
