Fast ping-pong arbitration for input-output queued packet switches

摘要

Input-output queued switches have been widely considered as the most feasible solution for large capacity packet switches and Ip routers. In this paper, we propose a ping-pong arbitration shceme (PPA) for output contention resolution in input-output queued switches. The challenge is to develop a high speed and cost-effective arbitration scheme in order to maximize the switch throughput and delay performance for supporting multimedia services with various quality-of-service (QoS) requirements.
