This paper deals with the application of a GCRA-based traffic shaping algorithm used in the source ATM end-point. Two scenarios are considered: for the first scenario, where the traffic on all the VCs originating in one user is collectively shaped, a discrete-time analysis model is developed. In the second scenario the traffic is shaped on groups of VCs having common features (e.g. same destination node), for which a traffic shaping architecture is constructed and an algorithm is proposed for scheduling the cell flows to the ATM link. The scheduling algorithm cooperates with the shapers in the traffic shaping architecture in order to ensure the conformity of the individual cell streams with the conformance test at the UNI point. Applications of the traffic shaping architecture are demonstrated with some analytical and simulation results in the topology of a potential Hungarian ATM backbone network.
