Abstract :
Based on the analysis of FTP process and investigation of user perceptions, a set of FTP service QoS parameters are proposed from the user´s perspective. These parameters are defined in terms of delay, throughput and usability. Detailed definition of each parameter is presented and its effect on user perceptions is well described. In order to evaluate the effectiveness of these parameters, an active measurement system was implemented. The system consists of a QoS-management server, a meter, and several target FTP servers. Measured results show that the set of QoS parameters we proposed can be used to get a comprehensive view of user-perceived FTP service QoS.
