The inclusion of integrated quality of service (QoS) support in existing and future networking technologies and protocols has become a highly relevant area of research. But the variety and heterogeneity of different approaches for QoS support on different protocol layers result in the need of a solution with an end-to-end overview and regulation of data flows in a controllable subnetwork. The ROBIN (Regulation Of Bandwidth in Intra-Networks) concept introduced in this paper is such a mechanism which controls the bandwidth used by data flows in heterogeneous networks in case of network congestion. This paper presents an overview of the concept and reports on the state of simulative performance analysis work on ROBIN.
