Practical experiences with a transport layer extension for end-to-end bandwidth regulation

The paper presents an extension of the transport layer to control the bandwidth used by data flows in heterogeneous networks in case of network congestion. The regulation mechanism is operating on an end to end basis. It does not depend on a negotiation of quality of service (QoS) parameters prior to the data transmission. Instead it uses a relative QoS concept based on a classification of data flow requirements specified by the application. The paper describes the concept of the mechanism for Regulation Of Bandwidth in Intra-Networks (ROBIN) and presents first measurement results with a prototype implementation of ROBIN.
