One of the most challenging problems in ATM network design is providing diversified Quality of Service (QoS) to applications with distinct characteristics. A flexible priority service policy for two applications (classes) with strict - and in general distinct - deadlines and different deadline violation rates (loss rates) is studied in this paper. The proposed policy is a generalization of the Shortest Time to Extinction (STE) policy (or the Early-Due-Date policy which discards expired cells). The relationship of this policy to other standard ones is also discussed. Performance measures such as cell loss, mean cell-delay and the tail of the cell-delay probability distribution are derived for each class. Numerical results illustrate the effectiveness of the studied priority scheme. Finally, a low-complexity implementation scheme is proposed, which does not require time-stamp-based sorting.
