In this paper, we focus on the regulations of the directive in the areas of Internet access, Internet e-mail, and Internet telephony. We analyze how the requirements of the directive can be satisfied and to what extent it is possible to achieve its objectives with the technical means currently available. Moreover, we estimate the resulting costs.enText/Conference Paper1617-5468
