Abstract
We propose an ATM traffic shaper for shaping multiple delay-sensitive and delay-insensitive VBR cell streams simultaneously, with a shaping mechanism following the definition of GCRA algorithm. By using a feedback mechanism between the regulator and the scheduler, the output streams are strictly conforming. In order to achieve best performance, we employ the Earliest-Due-Date (EDD) discipline to resolve cell emission conflicts. The call admission control condition and the cell delay bound for both classes of VBR traffic are derived. Simulation results demonstrate that the proposed traffic shaper can provide different bevels of QoS (delay bound) guarantees for delay-sensitive and delay-insensitive traffic. © 1998 IEEE.
