EMPoWER Hybrid Networks: Exploiting Multiple Paths over Wireless and ElectRical Mediums

Patrick Thiran, Julien Pierre Sacha Herzen, Christina Vlachou, Sébastien Christophe Henri

Several technologies, such as WiFi, Ethernet and power-line communications (PLC), can be used to build residential and enterprise networks. These technologies often co-exist; most networks use WiFi, and buildings are readily equipped with electrical wires ...

Software Dataplane Verification

Aikaterini Argyraki, Mihai Dobrescu

The industry is in the mood for programmable networks, where an operator can dynamically deploy network functions on network devices, akin to how one deploys virtual machines on physical machines in a cloud environment. Such flexibility brings along the th ...

Orthogonal multicarrier modulations in satellite uplinks

Stefano Rosati

In this paper, we analyze Orthogonal Frequency-Division Multiple Access and Single-Carrier Frequency Division Multiple Access as alternative physical layer schemes for the up-link of a satellite network. Both orthogonal frequency-division multiple access a ...

A High-Level Synthesis Flow for the Implementation of Iterative Stencil Loop Algorithms on FPGA Devices

David Atienza Alonso, Ivan Beretta, Alessandro Antonio Nacci

The automatic generation of hardware implementations for a given algorithm is generally a difficult task, especially when data dependencies span across multiple iterations such as in iterative stencil loops (ISLs). In this paper, we introduce an automatic ...

Practical Network Tomography

Denisa Gabriela Ghita

In this thesis, we investigate methods for the practical and accurate localization of Internet performance problems. The methods we propose belong to the field of network loss tomography, that is, they infer the loss characteristics of links from end-to-en ...

From Uncertainty to Nonlinearity: Solving Virtual Private Network via Single-Sink Buy-at-Bulk

Thomas Rothvoss, Laura Sanità

The virtual private network problem (VPN) models scenarios in which traffic is uncertain or rapidly changing. The goal is supporting at minimum cost a given family of traffic matrices, which are implicitly given by upper bounds on the ingoing and outgoing ...

Distance Bounding with IEEE 802.15.4a: Attacks and Countermeasures

Jean-Yves Le Boudec, Jean-Pierre Hubaux, Panagiotis Papadimitratos, Marcin Poturalski

Impulse Radio Ultra-Wideband, in particular the recent standard IEEE 802.15.4a, is a primary candidate for implementing distance bounding protocols, thanks to its ability to perform accurate indoor ranging. Distance bounding protocols allow two wireless de ...

Network Tomography on Correlated Links

Patrick Thiran, Aikaterini Argyraki, Denisa Gabriela Ghita

Network tomography establishes linear relationships between the characteristics of individual links and those of end-to-end paths. It has been proved that these relationships can be used to infer the characteristics of links from end-to-end measurements, p ...

Stable routing under the Spanning Tree Protocol

Laura Sanità

The Spanning Tree Protocol routes traffic on shortest path trees. If some edges fail, the traffic has to be rerouted consequently, setting up alternative trees. In this paper we design efficient algorithms to compute polynomial-size integer weights so as t ...

Multi-hop Broadcast from Theory to Reality: Practical Design for Ad Hoc Networks

Jean-Yves Le Boudec, Alexandre Fawal

We propose a complete design for a scope limited, multi-hop broadcast middleware, which is adapted to the variability of the ad-hoc environment and works in unlimited ad-hoc networks such as a crowd in a city, or car passengers in a busy highway system. We ...

Atomic broadcast : a fault-tolerant token based algorithm and performance evaluations

Nils Richard Ekwall

Within only a couple of generations, the so-called digital revolution has taken the world by storm: today, almost all human beings interact, directly or indirectly, at some point in their life, with a computer system. Computers are present on our desks, co ...

Tradeoff Analysis of PHY-aware MAC in Low-Rate, Low-Power UWB networks

Jean-Yves Le Boudec, Ruben Merz, Jörg Widmer, Alexandre Fawal

We are interested in the design of physical-layer aware medium access control (PHY-aware MAC) for self-organized, low power, low data-rate impulse-radio ultra-wideband (IR-UWB) networks. In such networks, energy consumption is much more of a concern than a ...

Object-oriented method and architecture for virtual private network service management

One of the major trends in the evolution of current corporate networking is an increasing need for high performance long distance communications. Provided as an alternative to leased lines networks, virtual private networks (VPNs) are gaining increasing ac ...

Prévention de la congestion dans le service “best-effort” des réseaux locaux ATM

In ATM local area networks, several kinds of traffic, such as data, video and voice, are likely to coexist. Some of this traffic has stringent delay and jitter requirements, which can only be guaranteed to be met through bandwidth reservation. In contrast, ...
