Estimating the loss probability in a multiplexer loaded with multi-priority MMPP streams

Future broadband integrated service digital networks (B-ISDNs) will carry a wide spectrum of applications with different loss requirements. By adopting a multi-priority scheme at the cell level, flexibility is gained in coping with these diverse requirements in an efficient way. The issue of furnishing a multiclass selective discard mechanism is addressed. The loss probability per class is computed where each class is modeled as a two-state Markov modulated Poisson process (2-MMPP₁... 2-MMPP_nD/1/K queue). A multiple class buffer priority algorithm that has linear complexity as a function of the number of classes is used. The advantages of a multi-priority scheme as well as the effect of the burstiness on the loss probability are illustrated
