The aim of this textbook is to provide students with basic knowledge of stochastic models
that may apply to telecommunications research areas, such as traffic modelling, resource …

Graphics processing units (GPUs) are being widely used as co-processors in many
application domains to accelerate general-purpose workloads that are computationally …

This paper presents solutions towards an efficient and intelligent network infrastructure for
Grid services, taking advantage of recent developments in optical-networking technologies …

We consider a circuit-switched multiservice network with non-hierarchical alternative routing
and trunk reservation. Based on the fundamental concept of overflow priority classification …

Contention is the main problem in optical burst switching (OBS) systems that lead to loss
more burst by dropping the contended burst. To deal with this problem, we propose a new …

Recently, the neural network approach for the blocking probability evaluation on optical
networks was proposed, in which the inputs of the neural network were the optical network …

Optical transmission has long been the established choice for nonwireless data
transmission spanning distances longer than a few tens of meters, due to its high bandwidth …

This paper provides a concise and up-to-date survey of major recovery (protection and
restoration) techniques for High Speed (Gbits/s) Next Generation Networks. The survey …

We provide teletraffic models for loss probability evaluation of optical burst switching (OBS).
We show that the popular Engset formula is not exact for OBS modeling and demonstrate …

The issue of burst losses imposes a constraint on the development of Optical Burst
Switching (OBS) networks. Heavy burst losses strongly affect the Quality of Service (QoS) …
