Dynamic Cost-Efficient Replication in Data Clouds

Karl Aberer, Nicolas Bonvin

Hardware failures in current data centers are common partly due to the higher data scales supported. Data replication is the common approach for improving availability. However, mostly static replication approaches have been proposed, i.e. the number of re ...

Loss-resilient window-based congestion control

Pascal Frossard, Christophe De Vleeschouwer

This paper addresses the problem of fair allocation of bandwidth resources on lossy channels in hybrid heterogeneous networks. It discusses more particularly the ability of window-based congestion control to support non-congestion related losses. We invest ...

The magnetic diagnostics set for ITER

Jean-Marc Moret, Duccio Testa, René Chavan, Jonathan Bryan Lister

The current status of the ITER magnetics diagnostic is summarised. The various risks are discussed on the basis of when they could be present during ITER operation and appropriate mitigation is reviewed. An implementation risk or common mode operation fail ...

User-level Internet tomography and overlay routing

Xuan Hung Nguyen

In this thesis, we study methods to detect, localize and overcome performance problems experienced by end-users in communication networks. These problems are extremely difficult to solve when the only available information are end-to-end data. We first con ...

Superstabilizing, Fault-containing Multiagent Combinatorial Optimization

Boi Faltings

Self stabilization in distributed systems is the ability of a system to respond to transient failures by eventually reaching a legal state, and maintaining it afterwards. This makes such systems particularly interesting because they can tolerate faults, an ...

An Adaptive Algorithm for Efficient Message Diffusion in Unreliable Environments

Rodrigo Malta Schmidt, Benoît Garbinato, Fernando Pedone

In this paper, we propose a novel approach for solving the reliable broadcast problem in a probabilistic model, i.e., where links lose messages and where processes crash and recover probabilistically. Our approach consists in first defining the optimality ...

Delay aspects in Internet telephony

Catherine Boutremans

In this work, we address the transport of high quality voice over the Internet with a particular concern for delays. Transport of interactive audio over IP networks often suffers from packet loss and variations in the network delay (jitter). Forward Error ...

Fault Localization at the WDM Layer

Jean-Yves Le Boudec, Patrick Thiran, Carmen Mas

A single failure in a communication network may trigger many alarms. When the communication network uses optical fibres as transmission medium and increases its capacity by using Wavelength Division Multiplexing (WDM), the number of alarms and the difficul ...

Fault Localisation for optical networks

Jean-Yves Le Boudec, Carmen Mas

A single failure in a communication network may trigger many alarms. When the communication network uses optical fibres as a transmission medium and increases its capacity by using Wavelength Division Multiplexing (WDM) and Space Division Multiplexing (SDM ...
