Traffic management plays an important role in providing differentiated quality of service and supporting the integration of a variety of broadband services within a common ATM network. Wireless ATM access networks are under definition in standards bodies as well as subject of various research activities and first field trials. The nature of the wireless medium requires new protocols that are able to cope with multiple access, error prone wireless channels and user mobility. When attaching a wireless ATM network to a fixed ATM network proper interaction of traffic and resource management functions throughout both networks is necessary to achieve stringent QoS objectives. In this paper the relation between mobile specific protocols and traffic management functions as well as their mutual impacts are discussed. Three key areas to enable seamless traffic management integration are identified and possible solutions are outlined.
