Abstract: Internet and ATM both aim at providing integrated services. Therefore they independently (more or less) developed QoS architectures. A realistic assumption certainly is that both will take their place and that they will coexist for quite some time. A likely place for ATM is in the backbone, while IP will probably keep its dominance on the desktop. It is thus valid to assume an overlay model for the interaction between the two QoS architectures. Crucial components of the QoS architecture of the Internet are its signalling protocol RSVP and the IP multicast architecture. Their integrated support by an ATM subnetwork and the issues arising with this are the focus of this paper. While other components of the QoS architectures like the QoS models, the management frameworks, the charging mechanisms, etc. need to be dealt with for a complete solution to the problem of overlaying IP's QoS architecture onto that of ATM, we will concentrate on the aforementioned points.
