The site also gives detailed statistics of the test results you get from the test. But to further improve the test’s accuracy, now does tests through direct Transmission Control Protocol (TCP) sockets and a custom protocol of communication between ISP servers and their clients. As of September of 2018, there are over 21 billion speed tests that have been made and completed by users.īack then, tests were previously made by the use of the Layer 7 HTTP protocol of the OSI model. The tests are typically made on the user’s web browser or the Speedtest by Ookla app itself. In other words, it determines the rate of data transfer from the ISP server to the user’s PC, and then the upload data rate, which is the rate of data transfer from the user’s PC back to the ISP server. Every test the app conducts will measure the data rate for download direction. The service evaluates the data speed and latency, also known as connection delay of a user’s internet connection when compared to one of 8,000 geographically dispersed servers. It was made by Ookla in 2006, based in Seattle, Washington, USA. and its app version Speedtest by Ookla is a service that gives users a free analysis of various internet access performance metrics, like your connection data rate, latency, and download speed.
