Even when data communications are made inside an all-IP domain, in a hybrid network different mechanisms and policies for the management of Quality of Service (QoS) could coexist in the different access networks and nodes involved. Specifically, in the scenario considered along this work, a WiMAX segment is included inside an IP network using the DiffServ protocol for QoS management. The conflict arises due to the different ways to handle and label traffic flows provided by the DiffServ protocol and the native Medium Access Control (MAC) layer QoS mechanism implemented and the lack of a one-to-one correspondence between the different classes of traffic defined in both domains.
