Segmented Adaptation of Traac Aggregates

Congestion control in heterogeneous Quality-of-Service (QoS) architectures remains a major challenge. The solution proposed in this paper entails three constituents. Taking the current trend towards Differentiated Services (DiiServ) as a likely candidate for future Internet QoS-architectures, the three constituent parts of this approach are based on aggregated congestion control, domain-based congestion control, and class-of-service based congestion control. Generally, the overall framework for congestion control, as suggested here, reeects essential properties of underlying QoS-architectures and their instantiations in real implementations. As such an approach calls for highly exible architectures, we suggest the use of Active Networking, and in particular Application Level Active Networking, as an enabling technology for a seamless and rapid integration of the proposed scheme into current architectures.
