Fair Packet Discard as Improvement of Early Packet Discard

Previous papers have described and evaluated theperformance of the Early Packet Discard techniquefor maintaining packet integrity during overload inATM switches.In this paper a packet discard scheme is proposedwith the goal to provide both good performance interms of throughput and fairness in terms of band-width exploitation of the output link among all vir-tual circuits. In the scenarios here considered, theproposed discard scheme is shown to provide verygood results and to represent therefore a remarkableimprovement of the classical Early Packet Discard.Numerical results are reported and discussed forcomparing these two discarding schemes under dif-ferent operating conditions.
