Abstract

The emphasis in this paper is on the trafic control at an ATM end source. The purpose of locally controlling a source is the improvement of the TCP pe$ormances over ATM. We argue the need of a policing mechanism less stringent than the Generic Cell Rate Algorithm proposed by the ITU. A more jlexible method which is suitable for providing performance guarantees in high speed networks is proposed in this papel: We present the results obtained by the implementation of this method in a multi-tasks environment. We show how we can obtain reasonable bandwidth utilization while remaining conform to the traffic contract limitations. Moreover, we present how this method achieves simplicity of implementation as well as flexibility in the allocation of bandwidth to difSerent connections.
