One of the main drawbacks of classical Optical Burst Switching (OBS) solutions is the loss of bursts when contentions occur. Time-domain Wavelength Interleaved Networking (TWIN) is a lossless solution with contention resolution in the edge nodes providing a simple and passive switching in the core nodes and satisfying both low-energy and efficient bandwidth(More)
This paper proposes a novel Metropolitan Area Network (MAN) architecture called Multi-hEad sub-wavElength swiTching (MEET). Compared with the current architectures, MEET proposes to aggregate traffic using passive optical nodes instead of using electrical nodes (switches and routers). Several options regarding a potential control plane are compared in terms(More)
Resource allocation mechanism remains a challenging issue in the conception of the actual and future networks. In this paper, we study several resource allocation schemes for the control plane of a lossless Optical Burst Switching (OBS) solution. We carry out a comparison of the proposed schemes using simulation approach. The performances of the proposed(More)
The increasing of traffic in transport networks, and consequently of the power consumption, is motivating to search new solutions to improve the energy efficiency of the networks. In this work, we investigate new switching paradigms based on time-domain optical sub-wavelength switching technologies and we determine the dimensioning of networks employing(More)
This paper reports a test bed aiming at studying burst contention resolution mechanisms in ldquoLabelledrdquo OBS networks together with a simulation tool that is designed to back up experiments. The test bed is composed of a Labelled OBS core node and a measurement arrangement for burst capture and analysis. Different components of the test bed are(More)
RESUME Dans cet article, nous montrons, à l'aide de simulations, les différents comportements de l'OBS conventionnel et de l'OBS à label vis-à-vis de la résolution de contentions spectro-temporelles. Nous montrons que le temps d'« offset » et les contentions de BCP sont les principaux inconvénients de l'OBS conventionnel entraînant des performances(More)
The continuous growth of traffic volumes is making the consumed energy, in telecommunication networks, a critical issue. In this context, the implementation of new content distribution solutions will speed up this traffic increase. In particular, these solutions will significantly impact the traffic profile in metro networks. The current centralized traffic(More)
