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.

Video Transport in ATM Networks

Video applications are expected to generate a significant proportion of the traffic in the future B-ISDN. We consider the different possibilities for the transport of video signals provided by the service classes defined by the ATM Forum and the ITU-T, foc ...

IP and ATM - current evolution for integrated services

Jean-Yves Le Boudec

This paper gives a technical overview of different networking technologies, such as Internet, ATM. It describes different approaches of how to run IP on top of an ATM network, and assesses their potential to be used as an integrated services network. Keywo ...

The Renegotiable Variable Bit Rate Service

Jean-Yves Le Boudec

A shaper is a system that stores incoming bits in a buffer and delivers them as early as possible, while forcing the output to be constrained with a given arrival curve. A shaper is time invariant if the traffic constraint is defined by a fixed arrival cur ...

A comparison of ABR and UBR to support TCP traffic

Jean-Yves Le Boudec

This paper compares the performance of ABR and UBR for providing high-speed network interconnection services for TCP traffic. We test the hypothesis that UBR with adequate buffering in the ATM switches results in better overall goodput for TCP traffic than ...

SMART: A Many-to-Many Multicast Protocol for ATM

Jean-Yves Le Boudec

We present a protocol for controlling a shared ATM multicast tree supporting many-to-many communication. The protocol supports one or several ATM VCCs of the many-to-many type. The number of VCCs is independent of the number of endpoints. The protocol guar ...

Virtual Trunk Simulation

One of the activities of the ACTS project EXPERT is to perform trials demonstrating the use of advanced Resource Management and Routing (RM&R) algorithms in ATM networks. The RM&R model chosen for these trials is based on the Virtual Trunk (VT) concept. In ...

IP and ATM - a position paper

Jean-Yves Le Boudec

This paper gives a technical overview of different networking technologies, such as Internet and ATM. It describes different approaches of how to run IP on top of an ATM network and assesses their potential to be used as an integrated services network. Key ...

Modélisation markovienne du trafic dans les réseaux de communication

The principal question we address in this work is the following: "Is Markov modelling appropriate to analyse data networks?". We will conclude that it is. The motivation for this question comes from the work of a research team at Bellcore who argue that th ...

Scalability Enhancements for Connection-Oriented Networks

Jean-Yves Le Boudec

We consider the issue of increasing the number of connections that connection or iented networks, such as ATM, can handle. We describe one step that aims at reducing connection awareness inside the netwo rk. To that end, connections between the same pair o ...

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 ...
