An algorithm for traffic enforcement in multi-tasks operating systems

The emphasis in the paper is on the traffic control at an ATM end source. The purpose of locally controlling a source is the improvement of the TCP performances over ATM. The authors argue the need of a policing mechanism less stringent than the generic cell rate algorithm proposed by the ITU. A more flexible method which is suitable for providing performance guarantees in high speed networks is proposed in the paper. They present the results obtained by the implementation of this method in a multi-task environment. They show how one can obtain reasonable bandwidth utilization while remaining conform to the traffic contract limitations. Moreover they show how this method achieves simplicity of implementation as well as flexibility in the allocation of bandwidth to different connections
