Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Efficient, self-contained handling of identity in Peer-to-Peer systems

Karl Aberer, Manfred Hauswirth, Anwitaman Datta

Identification is an essential building block for many services in distributed information systems. The quality and purpose of identification may differ, but the basic underlying problem is always to bind a set of attributes to an identifier in a unique an ...

Measurement and Analysis of Single-Hop Delay on an IP Backbone Network

Patrick Thiran

We measure and analyze the single-hop packet delay through operational routers in the Sprint Internet protocol (IP) backbone network. After presenting our delay measurements through a single router for OC-3 and OC-12 link speeds, we propose a methodology t ...

Handling Identity in Peer-to-Peer Systems

Karl Aberer, Manfred Hauswirth, Anwitaman Datta

Due to the limited number of available IP addresses most computers on the Internet use dynamic IP addresses which causes problems for applications that have to maintain rout-ing tables, for example, peer-to-peer systems. To overcome this we propose unique ...

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 ...

Secure Link State Routing for Mobile Ad Hoc Networks

Panagiotis Papadimitratos

The secure operation of the routing protocol is one of the major challenges to be met for the proliferation of the Mobile Ad hoc Networking (MANET) paradigm. Nevertheless, security enhancements have been proposed mostly for reactive MANET protocols. The pr ...

End-to-end Congestion Control for Flows with Variable Packet Size

Jean-Yves Le Boudec, Jörg Widmer, Catherine Boutremans

Current TCP-friendly congestion control mechanisms such as those used in TFRC adjust the packet rate in order to adapt to network conditions and obtain a throughput not exceeding that of a TCP connection operating under the same conditions. In an environme ...

Some Properties Of Variable Length Packet Shapers

Jean-Yves Le Boudec

The min-plus theory of greedy shapers has been developed after Cruz`s results on the calculus of network delays. An example of greedy shaper is the buffered leaky bucket controller. The theory of greedy shapers establishes a number of properties such as th ...

ABE: providing a low-delay service within best effort

Jean-Yves Le Boudec, Patrick Thiran, Paul Hurley

Alternative best effort (ABE) is a novel service for IP networks, which relies on the idea of providing low delay at the expense of possibly less throughput. The objective is to retain the simplicity of the original Internet single-class best-effort servic ...

SFIO a striped file I/O library for MPI

Roger Hersch, Emin Gabrielyan

This paper presents the design and evaluation of a Striped File I/O (SFIO) library for parallel I/O within an MPI environment. We present techniques for optimizing communications and disk accesses for small striping factors. Using MPI derived datatype capa ...

Open Consensus

Rachid Guerraoui, Romain Boichat

This paper presents the abstraction of open consensus and argues for its use as an effective component for building reliable agreement protocols in practical asynchronous systems where processes and links can crash and recover. The specification of open co ...
