Software Framework for Integrated Modelling and Dimensioning of Backbone Optical Networks

Modelling, dimensioning and performance analysis of optical backbone networks is the main concern of this thesis. Modelling consists in representing a network under a abstract form, simpler and easier to analyse, the model. Dimensioning is achieved when ne ...

Multi-objective optimization of regenerator placement using Constraint Programming

Sébastien Rumley, Christian Gaumier

In translucent optical networks, connections bypass most intermediate nodes transparently. However, their signal quality is affected by the traveled distance and/or the bypass operations. Hence, they might require optical-electrical-optical conversions at ...

Adaptive Burst Admission and Forwarding in OBS Networks

Sébastien Rumley, Christian Gaumier

This paper addresses the problem of controlling the performance of optical burst switching (OBS) networks in presence of non-stationary traffic demands. We propose a joint burst admission control and forwarding mechanism that operates in core nodes. This m ...

Cost Aware Design of Translucent WDM Transport Networks

Sébastien Rumley, Christian Gaumier

Fully-transparent DWDM networks working at 10 Gb/s or more have limited reach. At these high rates, only translucent networks able to fully regenerate the signal when needed can be used to implement long haul transport networks. Since signal regeneration a ...

Flexible simulators for OBS network architectures

Sébastien Rumley, Christian Gaumier

Since the OBS paradigm has become a potential candidate to cope with the needs of the future all optical networks, it has really caught the attention from both academia and industry worldwide. In this direction, OBS networks have been investigated under ma ...

Multi-Agent Approach to Electrical Distribution Networks Control

Sébastien Rumley

A new approach to the configuration and operation of electrical distribution networks is proposed. Traditionally, the medium-voltage part of the electrical grid is operated in a centralized and static manner. In the context of electric sector deregulation ...

Distributed RWA tools via Web Services

Sébastien Rumley, Christian Gaumier

Several computer tools addressing the routing and wavelength assignment (RWA) problem are available today within the research community. However, these tools have low flexibility and are difficult to use for remote or casual users. This paper shows how to ...

Pseudo Random Numbers Generators available as Web Services

Sébastien Rumley

Series of Pseudo Random Numbers are often used as simulation input, and they strongly Influence the results. Thus, their usage and the usage of their generator need to be taken care of very well. Qualified generators are available on the web as source code ...

Practical Approaches for Software Components Integration in Telecommunications

Sébastien Rumley, Christian Gaumier

Nowadays, advances in telecommunication network design and performance analysis often rely on dedicated software tools. Unfortunately, developing new tools is a very time and resources consuming activity. To rationalise development costs, existing applicat ...
