ABSTRACT:
An ATM user traffic control apparatus adopts an MBEA (most behind expected arrival) multiplexing mechanism for UNI (User-to-Network Interface) and adaptively controls ATM traffic streams that a plurality of traffic sources send into a UPC (Usage Parameter Control) unit of an ATM network in consideration of traffic priorities of the traffic streams. The traffic control apparatus is provided with a plurality of small leaky bucket buffers and a plurality of virtual bucket buffers corresponding to the leaky buckets, respectively. A pair of leaky and virtual buckets are provided for each traffic source. The apparatus also includes a detection unit that detects whether the cells drained from the leaky buckets are conforming cells and provides information regarding the traffic streams where there exist conforming cells. A calculation unit for calculating the values of priority functions of the traffic streams with the conforming cells, and a priority determination unit for determining a top priority traffic stream by comparing the priority function values are provided for the apparatus. An ATM service multiplexer sends the top priority traffic stream to the UPC unit in preference to the other streams.
