<p>A traffic management unit (10) for implementing Traffic Management (TM) of Available Bit Rate (ABR) traffic on an ATM network is disclosed. The traffic management unit (10) comprises a traffic management processor (42) coupled between a data processor (38) and an ATM interface (46) and to a traffic management memory (44). An Ethernet workstation (32) is coupled to the data processor (38) through an Ethernet interface (36). An ATM switch (48) is coupled to the traffic management processor (42) through the ATM interface (46). In order to utilize network congestion information, VCs are grouped according to their output destinations or their path through the network. Congestion feedback for one VC is applied to other VCs within the group. The traffic management setup procedure by using a preliminary profile (104) and modifying in accordance with feedback congestion data received (106). Memory-based lookup tables containing pre-calculated profile sets are utilized.</p> |
