Anypath routing

In many networks, it is less costly to transmit a packet to any node in a set of neighbors than to one specific neighbor. A well-known instance is with unreliable wireless links, where the probability that at least one node out ofnreceives a packet increas ...

Numerical parametric lens for shifting, magnification and complete aberration compensation in digital holographic microscopy

Christian Depeursinge, Tristan Colomb, Etienne Cuche, Frédéric Montfort, Nicolas Aspert, Pierre Marquet, Jonas Kühn, Florian Charrière, Stéphane Bourquin, Mihaela Marian

The concept of numerical parametric lenses (NPL) is introduced to achieve wavefront reconstruction in digital holography. It is shown that operations usually performed by optical components and described in ray geometrical optics, such as image shifting, m ...

On the Long-Run Behavior of Equation-Based Rate Control

Jean-Yves Le Boudec, Milan Vojnovic

AbstractWe consider unicast equation-based rate con-trol, where, at some points in time, a sender adjusts its rate to f(p,r), where p is an on-line estimate of the loss-event rate observed by this source, r of the average round-trip time, and f is a TCP th ...

Improving TCP Performance in Ad Hoc Networks Using Signal Strength Based Link Management

Fabius Klemm

Mobility in ad hoc networks causes frequent link failures, which in turn causes packet losses. TCP attributes these packet losses to congestion. This incorrect inference results in frequent TCP re-transmission time-outs and therefore a degradation in TCP p ...

We consider unicast equation-based rate con-trol, where, at some points in time, a sender adjusts its rate to f(p,r), where p is an on-line estimate of the loss-event rate observed by this source, r of the average round-trip time, and f is a TCP throughput ...

Robust TCP Connections for Fault Tolerant Computing

André Schiper, Nils Richard Ekwall

When processes on two different machines communicate, they most often do so using the TCP protocol. While TCP is appropriate for a wide range of applications, it has shortcomings in other application areas. One of these areas is fault tolerant distributed ...

Design Protection for WDM Optical Networks

Jean-Yves Le Boudec, Olivier Crochat

With WDM networks, the failure of a single link or component may cause the simultaneous failure of several optical channels, potentially making impossible the restoration by rerouting in higher layers directly using the optical network (SDH, ATM, IP). To a ...

An Evaluation of Software Release-Consistent Protocols

Willy Zwaenepoel, Sandhya Dwarkadas

This paper presents an evaluation of three software implementations of release consistency. Release consistent protocols allow data communication to be aggregated, and multiple writers to simultaneously modify a single page. We evaluated an eager invalidat ...

Interconnecting heterogeneous networks to osi with a global name scheme and gateway address mapping.

Philippe Janson

The ongoing development of the OSI standards for computer communication prompts existing networks to provide OSI inteconnectivity. Achieving this requires two mechanisms: a global scheme to name applications, and specific solutions to provide internetwork ...

Interconnecting osi and non-osi networks using an integrated directory service

Philippe Janson

The emergence of OSI as an international standard is fostering a desire to interconnect existing networks and network architectures to OSI. In order to achieve this, a global scheme is necessary to provide object identification, and specific solutions are ...
