In this paper the problem of flow control in fast communication networks is considered. A new sampled time algorithm governing the source behaviour is proposed. The algorithm combines Smith principle with the conventional dead-bit controller. It guarantees full link utilisation and no cell lossin the controled virtual circuit. Consequently, the need of cell retransmission is eliminated. Furthermore, transmission rates generated by the algorithm can always be limited to an arbitrary level greater than the maximum available bandwidth of the controlled connection. A simulation example confirms favourable performance of the proposed controller.
