We consider a branch of queueing theory, retrial queueing systems, which is characterized
by the following basic assumption: a customer who cannot receive service (due to finite …

In this work, we present a bibliography on retrial queues which updates the bibliography
published in this journal in Artalejo (1999)[7]. The bibliography is focused on the progress …

A comprehensive study in efficient multi-rate teletraffic loss models used for designing,
performance analysis, and optimization of systems and networks Efficient Multirate …

This article proposes models of product-form state-dependent class of systems. Two
methods for determining the occupancy distribution and the blocking and loss probability in …

The ever increasing demand of elastic and adaptive services, where in-service calls can
tolerate bandwidth compression/expansion, together with the bursty nature of traffic …

Optical access systems are now considered a feasible alternative to the predominant
broadband access technologies, while, at the same time, passive optical networks (PONs) …

The Erlang Multirate Loss Model (EMLM) has been widely used as a springboard in the
study of multirate loss systems. In this paper, we study an extension of the EMLM in order to …

This article discusses a discretized model of resources to which a mixture of multi-service
traffic streams is offered. In the model the connections of individual traffic classes that require …

Bursty traffic is dominant in modern communication networks and keeps the call-level QoS
assessment an open issue. ON-OFF traffic models are commonly used to describe bursty …

The article proposes a new method of determining traffic characteristics of multiservice
overflow systems that carry adaptive traffic. When the total offered load in primary resources …
