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.

Age of Information: The Gamma Awakening

Elie Najm, Rajai Nasser

Status update systems is an emerging field of study that is gaining interest in the information theory community. We consider a scenario where a monitor is interested in being up to date with respect to the status of some system which is not directly acces ...

An LP Characterization of the Secret-message Capacity of Three Erasure Networks With Feedback

Christina Fragouli, Suhas Diggavi, László Czap, Vinod Malathidevi Prabhakaran

This paper presents exact capacity characterizations for the case, when a principal, Alice, wants to securely send a message to another principal, Bob, over three network configurations: the parallel edges network, the V-network, and the triangle network. ...

Simplifying Development and Management of Software-Defined Networks

Peter Peresini

Computer networks are an important part of our life. Yet, they are traditionally hard to manage and operate. The recent shift to Software-Defined Networking (SDN) is promised to change the way in which the networks are run by their operators. However, SDN ...

Software Dataplane Verification

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 ...

Building Evolvable Networks

Mihai Dobrescu

Software packet-processing platforms--network devices running on general-purpose servers--are emerging as a compelling alternative to the traditional high-end switches and routers running on specialized hardware. Their promise is to enable the fast dep ...

Tornado Attack on RC4 with Applications to WEP & WPA

Serge Vaudenay, Martin Vuagnoux, Pouyan Sepehrdad, Petr Susil

In this paper, we construct several tools for building and manipulating pools of biases in the analysis of RC4. We report extremely fast and optimized active and passive attacks against IEEE 802.11 wireless communication protocol WEP and a key recovery and ...

Systematically testing OpenFlow controller applications

Dejan Kostic, Marco Canini, Peter Peresini, Maciej Leszek Kuzniar, Jennifer Rexford

The emergence of OpenFlow-capable switches enables exciting new network functionality, at the risk of programming errors that make communication less reliable. The centralized programming model, where a single controller program manages the network, seems ...

On Multi-Dimensional Privacy in Context-Aware Mobile Networks

Igor Bilogrevic

By the end of 2013, the number of internet-connected mobile devices is expected to exceed that of humans. Omnipresent and context-aware, mobile devices enable people to communicate and exchange data anytime and almost anywhere. The myriad of ”digital footp ...

XOR-Based Encoding With Instantaneous Decoding for the Broadcast Erasure Channel With Feedback: The Three-User Case

We study the case of a three-user broadcast erasure channel with multiple unicast traffic sessions, where feedback from the users is fed back to the transmitter in the form of positive acknowledgment (ACK)/negative acknowledgment (NACK) messages. The capac ...

Decoding Delay Minimization in Inter-Session Network Coding

Pascal Frossard, Nikolaos Thomos, Eirina Bourtsoulatze

Intra-session network coding has been shown to offer significant gains in terms of achievable throughput and delay in settings where one source multicasts data to several clients. In this paper, we consider a more general scenario where multiple sources tr ...
