A method for network analysis in an access network () in connection with a data transmission network, in particular an xDSL network, with a plurality of subscriber lines (-). The method comprising the step of collecting data on physical layer operational parameters ({&#x3c6;}) of at least one subscriber line (-) and the steps of simulating a behavior of higher network layers based on said collected data when deploying at least one application (-) on said subscriber line (-); generating data on higher layer performance parameters for said application (-); and generating an advice signal (AS) based on said data and indicative of the compatibility of the physical layer/application couple with predetermined Quality-of-Service (QoS) requirements for said application (-). Thus, the proposed method provides network operators with information concerning the question if a given service application (-) will run on a respective data transmission (core and access) network (') in accordance with the QoS values recommended for said application (-), in particular a high-bandwidth rich media service type application, e.g. a triple-play service.
