An device (D) for drawing map of server quality in a fixed communication network, the network includes communication lines which connect network device (Ci) to communication terminal (T) through server access point (MD). The device (D) comprises i) control device (MC1), which is suitable to order network management device (EG) connecting to the network device (Ci) to confirm analysis data about the terminal (T) and/or the network device (Ci) which locates in the area selected by network and has been selected server quality and/or business state; ii) collecting device (MC2), which is suitable to collect the confirmed analysis data; as well as iii) processing device (MT), which is suitable to confirm the geography position of the terminal (T) and/or network device (Ci) involved by the analysis data, then correlate the position and corresponding analysis data, as well as transmit the analysis data correlating to at least a plurality of network devices (Ci) and/or terminals (T) of each selected area with drawing mode, so as to process the analysis data.
