(English Abstract)
Currently the research on input-queued ATM switches is one of the most active research fields. Many achievements have been made in the research on scheduling algorithms for input-queued ATM switches and also applied in commerce. The scheduling algorithms have the characteristic of improving throughput, satisfying Qos requirements and providing service fairly. In this paper, we studied on an implementation of scheduler which arbitrates the input-queued ATM switches efficiently and swiftly. The proposed scheduler approximately provides 100% throughput for scheduling. The proposed algorithm completes the arbitration for N-port VOQ switch with 4-iterative matching. Also the proposed algorithm has a merit for implementing the scheduling algorithm with 1/2 area compared to that of iSLIP scheduling algorithm which is widely used. The performance of the proposed scheduling algorithm is superior to that of iSLIP in 4-iterative matching. The proposed scheduling algorithm was implemented in FPGA and verified on board-level
