Quality of service (QoS) is becoming an attractive feature for high-performance networks and parallel machines because in those environments there are different traffic types, each one having its own requirements. In that sense, deadline-based algorithms can provide powerful QoS provision. However, the cost associated with keeping ordered lists of packets makes these algorithms impractical for high-performance networks. In this paper, we explore how to adapt efficiently the Earliest Deadline First family of algorithms to the high-speed network environments. The results show an excellent performance using just two virtual channels, FIFO queues, and a cost feasible with today's technology.
