Interaction approaches for Internet and ATM quality of service architectures

Internet and ATM possess quality of service (QoS) architectures which allow them to integrate services of data and telecommunications formerly performed by separate infrastructures. We believe that none of them will be able to oust the other. That means both will exist for at least the middle-term future. Therefore, an interaction between both is necessary, especially in the field of distributed multimedia applications where both worlds “meet” first. These applications require a certain QoS to perform gracefully. Hence, in particular the interaction between Internet and ATM QoS architectures is important. Interaction approaches for the QoS architectures developed for the Internet and for ATM are discussed. We do not restrict ourselves to common approaches but derive more unconventional models by regarding the possible communication patterns based on different topological variants for heterogeneous IP-ATM networks
