Performance overview of the quasi-synchronous operation mode in optical burst switching (OBS) networks

Sébastien Rumley, Christian Gaumier, Oscar Pedrola Escriba

Optical burst switching (OBS) is able to operate under both asynchronous and synchronous burst departures. Although the asynchronous approach is generally assumed in OBS owing to its simplicity and low technical requirements, it has been shown that perform ...

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 ...

Resource Utilisation Analysis in WDM Backbone Networks

Sébastien Rumley, Christian Gaumier

Circuit-switched backbone networks are appealing especially due to their low switching cost. However, some of their links may be poorly utilised with respect to the available capacity. Grooming can be used to improve this utilisation: optically switched li ...

Energy saving perspectives of IP over wavelength division multiplexing

Sébastien Rumley, Christian Gaumier

The electrical consumption of the core global networks is becoming preoccupant. To reduce it, one may bet on technological advances improving the energetic profile of individual components. However, large energy savings can potentially already be achieved, ...

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 ...

A Performance Survey on Deflection Routing Techniques for OBS Networks

Sébastien Rumley, Christian Gaumier

In this paper, we present a survey comparing different deflection routing based techniques applied to optical burst switching (OBS) networks. For such study we consider the E-OBS architecture proposed in [1] which is an advantageous solution for OBS networ ...

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 ...

Software Tools and Methods for Research and Education in Optical Networks

Sébastien Rumley, Christian Gaumier

Recent advances in photonic communication networks require planning, modelling and simulation tools of ever increasing scope and complexity. Based on valid and credible models, simulators are used heavily to investigate and assess new solutions before impl ...
