Speed Test – How It WorksĮxisting Internet Speed Tests – bandwidth testing techniques are not suitable because link asymmetry and ATM traffic shaping in xDSL deployments impact the accuracy of their speed test measurements.Ī number of techniques exist for Speed Test and bandwidth measurement. If not, it could indicate Internet speed congestion or a bad broadband connection.Īnything less that 100 would be ideal for this broadband speed test. Max Pause is the longest pause recorded during the Broadband Speed Test data download.

The faster (smaller) the RTT, the better broadband speed you’ll have.įor Voice over IP, round trip delays can occur when results exceed 250 mSec or 150 mSec one way which is also considered the maximum desired one-way latency to achieve high-quality voice. The Round Trip Time (RTT) reports the total time in milliseconds (ms) to send a small data packet in our internet speed test and obtain a reply back. This does not mean that you won’t find success at lower speeds, but on average, the speed test should report >= 80. This figure should come in around 80 or higher yet.

High quality plus internet speed provides better connections for VoIP (voice over IP), Citrix and other high traffic applications. The higher QOS percentage, the higher the overall quality of the internet connection.

Represents the level of consistent download capacity provided by your Broadband or DSL provider. The following internet speed test terms are useful for understanding the Speed Test measurement report: This speed test uses Java and will not work with java disabled. We have put great effort into providing an accurate, easy to understand graphical interface that clearly displays the results of the internet speed test.įor those of you interested in greater detail, keep reading otherwise, just click the speed test start button. In researching Broadband Speed Tests, we also found some very ‘unfriendly’ user interfaces that left us confused as to the results.

The paper explains in detail how to accurately measure Digital Subscriber Line Networks and is used by our speed test. To give you the most accurate results, our internet speed test was based on a research paper by Liang Cheng2 and Ivan Marsic from the Department of Electrical and Computer Engineering at Rutgers, the State University of New Jersey. A speed test also has to consider the technology used to deliver those packets of data and account for variations in speed.

There is a lot more to an internet speed test than meets the eye! When you measure bandwidth, be it DSL speed Test, Cable Modem Speed Test or any other, you have to consider the devices the packets of data travel through. It would be greatly appreciated if you would notify us of any problems with this speed test – Thank you! You can also try our very popular Broadband Speed Test and / or our Speed Test which also supports any language in the world! If this does not work, please let me know and I’ll work with you on this. If you still can not run the bandwidth test, download the latest version of Java. Here is an example of the IP Security Policy on a XP machine: What does this mean? If you see a ‘connect time out’ message, then you need to tell your firewall to allow 149.28.116.7 (that’s our server) to communicate with your computer using TCP port 8500. This test accurately measures bandwidth and serves as a DSL speed test and Cable Modem Speed test to help visitors troubleshoot and locate bandwidth issues.īefore you start the Speed Test, please keep in mind that it uses TCP port 85 to 8609 to test packets.
