Abstract
Access speed became the most commonly published metric for characterizing the quality of broadband offerings by Internet Service Providers. Obviously, this applies for both wired and wireless access technologies. However, measurements of speed for the same service can vary significantly, not mentioning frequent difference between download and upload direction given by the design of the technology. Moreover, we should care about many other parameters, starting from round-trip time, type of interconnection with other networks, unaltered Domain Name System communication, possibility to use any kind of application and not omitting sophisticated Quality of Service tests. Currently, not only in Europe, there is significant attention to so-called network neutrality issues and regulations that in wider meaning also address these topics. This talk is meant to introduce ideas, standards and tools covering measurement of basic parameters of IP networks in European context and to present possible approaches how to measure these parameters in IP-based networks.
