Multiple traffic classes are differentiated using different offset times per class. Assuming Poisson burst arrivals and phase-type distributed burst lengths, we exactly solve for per-class blocking probabilities using the well-known theory of feedback Markov fluid queues.EnglishObsHorizon reservationOffset-based service differentiationMarkov fluid queuesArticle10.1109/LCOMM.2009.081139
