The purpose with TPTEST is to allow users to measure the speed of their Internet connection in a simple way. TPTEST measures the throughput speed to and from various reference servers on the Internet. The use of TPTEST may help increase the consumer/end user knowledge of how Internet services work. TPTEST was originally developed by the Swedish ICT-commission, then later by the Foundation for Internet Infrastructure (iis.se), the Swedish Consumer Agency (konsumentverket.se), and the Swedish National Post- and Telecom Agency (pts.se). The latest development has been to separate the platform-independent test method software (the test engine) from the platform-dependent user interface software in order to make it easier for anyone to write a test client or server that uses the TPTEST testing method. The test engine code is to be regarded as a library module and is released under the LGPL license while the reference client/server applications is released under the GPL license.
