Despite the end of the Internet bubble, operators continue to increase the capacity of their networks. The question application-application application * * * * n (0senaler) v -, _~~~~~~~~~~~~(i&eiver) layer now rises whether these improvements still result in faster d ei communications, or whether most flows are limited by other aspects. In order to answer this question, actual network traffic TCP TCP TCP needs to be analyzed. Therefore, in this paper methods are S~~~~~~~~~~( sendleA(rcier)
