SIMPLE ANALYTICAL SOLUTIONS FOR THE Mb/Ek/1/m, Ek/Mb/1/m, AND RELATED QUEUES

In this paper we revisit some classical queueing systems such as the M-b and E-k/M-b Illtn queues, for which fast numerical and recursive methods exist to study their main performance measures. We present simple explicit results for the loss probability and queue length distribution of these queueing systems as well as for some related queues such as the M-b/D/1/m queue, the D/M-b/l/m queue, and fluid versions thereof. In order to establish these results we first present a simple analytical solution for the invariant measure of the M/E-k/1 queue that appears to be new.
