    New type of Speedtest

    Yall should give this a shot, it really helps measure "Bursting" such as what Comcast offers along with a more accurate speedtest result!

    The binary for windows is just a simple running program that doesn't install...works great!

    Here is mine:

    DiffProbe beta release. October 2009. Build 1002.
    Shaper Detection Module.

    Connected to server 203.5.76.164.

    Estimating capacity:
    Upstream: 3473 Kbps.
    Downstream: 21131 Kbps.

    The measurement will take upto 2.5 minutes. Please wait.

    Checking for traffic shapers:

    Upstream: Burst size: 4036-4124 KB;
    Shaping rate: 1045 Kbps.

    Downstream: Burst size: 9031-9681 KB;
    Shaping rate: 6421 Kbps.

    Works fine for me using FF and IE, can't really link the direct files if your having issues going to the site since that's where the files are hosted.

    It was quite "optimistic/inflated" when I ran it. I know for a fact I'm on a fixed rate line, no bursting at all, and I further have QoS on my firewall which throttles the flow to what I set it to...and I can test and confirm that with many other speed tests. This one gave me about 20% higher rates than what I'm really at.

    Seems kinda high, shouldn't my shaping rate for downstream be my non burst speed? Is capacity suppose to be theoretical?

    The main purpose is to not only show your speeds but if your getting your traffic shaped which we all know most ISP's do it.

    The goal of DiffProbe is to detect if an ISP is classifying certain kinds of traffic as "low priority", providing different levels of service for them. DiffProbe actively (and non-intrusively) probes the network path and tries to diagnose the nature and extent of traffic discrimination. This page presents a module of DiffProbe, called ShaperProbe. ShaperProbe tries to answer the question:


    Is the ISP shaping my traffic? In other words, is my "connection speed" dropped automatically to a low rate after some time?


    We detect traffic shaping, which means that the customer gets a large rate for a certain number of bytes, and then the rate is dropped automatically to a lower value. If a user gets rate limited for certain time periods, he/she can detect that observing the capacity estimates given by ShaperProbe.

    Right..that was immediately understood from their site, and I support ISPs lowering certain types of traffic through shaping...such as torrent/p2p. However...like I stated, I'm on a straight up biz connection at my office, and I know for a fact that my ISP does no "bursting" packages...I've been in their data center, talked with their techs, talked with their main tech, and I'm a reseller of their biz package.

    So I know exactly what's coming in from my pipe.
    And I know exactly how much I have allowed through my firewall, at a rate that I set.

    It's reporting quite a bit higher than it should be. Still needs to cook in the oven a bit more.

    Need to differentiate "traffic shaping" from the "boost" packages that many cable ISPs offer, it's quite different. And there is no way to reliably measure the "boost" packages...as it's simply any unused bandwidth from your node at that current moment. The only way to reliably replicate data on that is to unplug everyone else on your node...else it will always be a constantly changing variable based on what else is going on in your node.

    So then its very wrong.

    Because after the powerboost is over I don't get 17mbps.

    Meh.. I think its a good over all test, I mean I still use speedtest.net but it seems its widely accepted to be a very good type of traffic shaping test along with speed test used by the dslreports folks as well.

    Don't shot the messenger here.... feel free to email or contact those guys that made it and vent all you like.

    I'll walk backwards on that to "assume" otherwise....but who knows. Still, its something to toss around and experiment with.

    I have no idea what you mean by the walking backwards comment.

    I searched a bit and found a few threads about it, one on dslreports, and the consensus seems to be that Partha needs to include more documentation.

    It does look interesting as does the whole diffprobe project.
