Abstract
Previous papers have described and evaluated the performance ofpacket discard techniques for maintaining packet integrity during overloadin ATM switches but without taking into account different classes of service.In this paper a packet discard scheme is proposed with the goal toprovide incoming flows of cells with output link bandwidth dependingon the class of service they belong to. Also good performance in termsof throughput and fairness in bandwidth sharing among equal priorityflows are considered as the requirements to meet.In the scenarios here considered, the proposed discard scheme is shownto provide very good results and to represent a possible solution fordealing with the most demanding data flows during congestion intervals.Numerical results are reported and discussed for differentoperating conditions and traffic patterns.
