Ensuring correct network behavior is hard. This is the case even for simple networks, and adding middleboxes only complicates this task. In this paper, we demonstrate a fundamental property of networks. Namely, we show a way of using a network to emulate t ...
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 ...
The demand for capacity is growing exponentially with about 40-60% per year passing the installed network capacity. For the last two decades the transmission capacity per fiber has increased by more than three orders of magnitude: Single channel (wavelengt ...
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 ...

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, ...

This report is a research extract of my master thesis internship at the National Institute of Informatics (NII) in Tokyo, Japan. This report describes in details the created and optimized design of a single-photon source based on time and space multiplexin ...
This paper presents a systematic computational study on the performance of distributed optimization in model predictive control (MPC). We consider networks of dynamically coupled systems, which are subject to input and state con- straints. The resulting MP ...
We consider multisource non-coherent network coding, where multiple sources send information to one or multiple receivers. We prove that this is equivalent to a ldquosubspacerdquo channel, that takes subspaces as inputs and outputs. We then show that the r ...
We present an RF-driven two-stage 40 GHz RZ pulse source based on self-phase modulation and a fiber optic parametric amplifier, for generation of 1.1 ps pulses, and demonstrate generation of OTDM data up to 320 Gb/s. ...
Adaptive networks rely on in-network and collaborative processing among distributed agents to deliver enhanced performance in estimation and inference tasks. Information is exchanged among the nodes, usually over noisy links. The combination weights that a ...
