Mixture models arise when at least two different distributions of data sets are presented. In this paper, we introduce the upper and lower bounds for the steady-state performance of a multiserver model of the network node, with Exponential-Pareto mixture distribution of service times. We use the failure rate and stochastic comparison techniques together with coupling of random variables to establish some monotonicity properties of the model. These theoretical results are illustrated by numerical simulation of GI/G/N queueing systems.
