This paper presents a software tool whose aim is to quantify the level of network awareness and friendliness of the currently deployed Internet P2P applications. Considering such systems as black-boxes, the authors passively measure the traffic they generate and they gather, by means of both passive inference and active-probing techniques, some quantities relevant for their description. Observed metrics include, e.g., the amount of traffic that the peer under observation exchanges with peers belonging to the same Autonomous System or geographical Country. Similarly, they inspect the traffic exchanged in terms of its proximity in the underlying IP networks, expressed e.g., as RTT delay or number of IP hops.
