Cooperative Rate Control in ATM Networks

This paper introduces the concept of a bottleneck-switches cooperation in the explicit rate-control framework of Asynchronous Transfer Mode (ATM) networks. The proposed controller regulates the rates of available bit rate (ABR) traffic class and requires only local information exchange between bottleneck nodes. A sufficient condition for network closed loop stability is given and it is used for switch-controller parameters design. A realistic numerical validation is carried out by a discrete packet simulator.
