This paper presents the application of QoS about a heterogeneous network based on DWDM transmission technique as core and having as edges two technology platforms, ATM and Ethernet applied QoS in residential services such as VoIP, video conferencing, digital television and data link high rates of transmission. With this design and implementation performance were performed measurements to services implemented in two topologies with QoS and without QoS, obtaining as a result QoS policies implemented in the network.
