Abstract

See full text

A scheduling system for distributing asynchronous transfer mode (ATM) telephone signals from an ATM cell queuing device. The scheduling system includes a number of port shapers. A port shaper can support a number of flows with each flow identifying a number of ATM cells. A port shaper directs the subscriber. Each flow assigned to a port shaper identifies ATM cells which are to be distributed to a different device used by a subscriber, such as a telephone or computer. A port shaper further includes a number of time descriptors. Flows are linked to the time descriptors. The time descriptors are sequentially activated. When a time descriptor becomes active, a flow linked to the time descriptor can emit an ATM cell, and after emitting the cell the flow is relinked to subsequent time descriptors based ona weighting increment I to accommodate different device bandwidths.
