ABSTRACT:
A control method and architecture is described for an ATM network carrying connectionless data traffic. The method is capable of integrating connection-oriented as well as connectionless traffic. The method takes advantage of the quasi-deterministic nature of the traffic emanating from a source that is being shaped by the leaky bucket shaping algorithm. Alternative methods are provided if such a shaping algorithm is not provided by the CPE which methods still guarantee performance that equals or exceeds shared media networks such as FDDI. Hardware and software embodiments of the methods are disclosed. The invention is particularly applicable to LANs and hubs.
