This paper proposes a high-speed contention resolution scheme featuring high flexibility to the bursty traffic for an input buffering ATM switching architecture and its hardware strategy. The scheme is based on the threshold on the occupancy of the input buffer. As the proposed scheme utilizes the threshold, it has high flexibility to the fluctuations of the input traffic. The hardware strategy for the proposed policy is provided with the aim of the simple structure that achieves the reduction of the signal path and the power consumption. The performance on the average buffer size of the proposed policy is performed and compared with the conventional schame under the bursty traffic through both the analysis based on the markov hain and the simulation. The relations among the parameters on the proposed policy is analyzed to improve the performance.
