Abstract

A method for flexible inverse multiplexing for ATM and for link grouping (106) of communication links (103, 104, 105) with different transmission rates and delay. The method of the present invention supports links which use a portion of the link bandwidth for one QoS objective (e.g., low delay) and another portion for another QoS objective (e.g., low cell loss). The method involves servicing each of a number of multiplexed flows (300) with a predetermined number of cells. Cells (309) are assigned to each flow (302, 304, 306) during a number of cycles which make up an ATM frame. The number of cells assigned to each flow during each cycle is dynamically adjusted based upon the requirements of each flow, and may be different for each flow. The number of cells assigned to each flow during each cycle may either be fixed, or may vary from cycle to cycle.
