Abstract :
In this paper, we propose an efficient scheduling scheme called multi-layer gated frame queueing (MGFQ) for real-time traffic over ATM networks. ATM switches equipped with the function of MGFQ which employs only one set of FIFO queues can provide real-time multimedia communication with a wide range of QoS requirements. In addition, a hybrid design which combines MGFQ scheme with an age priority packet discarding (APPD) scheme is proposed to enhance packet level QoS. The simulation results show that the cell level performance as well as the packet level QoS can be improved simultaneously when applying this hybrid design
