With the increasing convergence of the data and voice networks, the use of this net for applications that need guarantees of parameters, as width of band, delay, variations of delay and tax of losses of packages, becomes necessary the use of quality of service. In this work, a management environment was developed to assist in the control of the quality of service through active measurements. These measurements had facilitated the attainment of information that permits us a fast action in the case of fall of the performance waited for the voice segment on IP. The results had been measured in terms of losses of percentile packages and variation of the delay in the packages (jitter). Some sizes of packages for verification of the influences of the use of QoS had been used. The results of the measurements in nets with QoS and without QoS had been compared, showing that the control of the parameters of QoS is efficient to improve the performance of the applications that demand priorities in the traffic. The architecture of marking DiffServ used in the routers revealed effective for maintenance of the quality of service.
