<span lang="en">Data network Quality of Service (QoS) measurement and evaluation is a challenge being deeply studied nowadays. Measurement techniques and methodologies are broad available, but they are not connected among them, this is, the evaluation is based on raw parameters. In this paper we present a proposal of an integrating architecture which can evaluate user's perceived QoS, merging results obtained by different measurement tools in order to acquire a better knowledge of the communication link than using a single parameter. Extra effort is made to develop a set of easy to use and understand measurement tools.</span>
