Exploring the use of DTA for origin-destination matrix estimation

André-Gilles Dumont, Edward Chung, Emmanuel Bert

Traffic simulation is more and more widely used and a helpful decision tool for planer and managers. Several tools exist and could be grouped in two main families: Macrosimulators with aggregate vision of the traffic in the network and microsimulators whic ...

Self-Limiting Epidemic Forwarding

Jean-Yves Le Boudec, Alaeddine El Fawal

We define a self-limiting epidemic service as a dissemination service for ad-hoc environments that is broadcast in nature, but is limited to a local scope around each source. Example applications are chatting or bulletin boards in a traffic jam, in an inst ...

Layered Complex Networks

Patrick Thiran, Maciej Kurant

Many complex networks are only a part of larger systems, where a number of coexisting topologies interact and depend on each other. We introduce a layered model to facilitate the description and analysis of such systems. As an example of its application, w ...

From car traffic to production flows

Roger Filliger

The purpose of this thesis is to show on explicit examples how various theoretical concepts, ranging from statistical mechanics to stochastic control and from traffic theory to queuing systems, can be transferred to transport processes, encountered in part ...

Modeling Internet backbone traffic at the flow level

Patrick Thiran

Our goal is to design a traffic model for non congested IP backbone links, which is simple enough to be used in network operation, while being as general as possible. The proposed solution is to model the traffic at the flow level by a Poisson shot-noise p ...

Seeing the wood and the trees: simulation-based evaluation of the effect of variable speed limit signs on capacity and user safety

Michel Bierlaire, André-Gilles Dumont, Alexandre Torday

This article describes how a simulation-based evaluation methodology was applied on a variable speed limit signs (VSLS) system designed for a heavily-traveled roadway around Lausanne, Switzerland. Using the MITSIM Laboratory, the evaluation focused on dete ...

Analysis of power consumption on switch fabrics in network routers

Giovanni De Micheli, Luca Benini

In this paper, we introduce a framework to estimate the power consumption on switch fabrics in network routers. We propose different modeling methodologies for node switches, internal buffers and interconnect wires inside switch fabric architectures. A sim ...

A flow-based model for Internet backbone traffic

Patrick Thiran

We model traffic on an uncongested backbone link of an IP network using Poisson Shot-noise process and M/G/

queue. We validate the model by simulation. We analyze the model accuracy with real traffic traces collected on the Sprint IP backbone netwo ...

Regulation of a Connection Admission Control Algorithm

Jean-Yves Le Boudec, Patrick Thiran

Connection Admission Control (CAC) algorithms are used to decide whether an incoming connection should be accepted or rejected in a node of a network offering reservation based services in order to maintain the guaranteed Quality of Service (QoS) in the ne ...

Analysis of traffic models for dynamic equilibrium traffic assignment

Dynamic traffic assignment provides a valuable means to investigate congested road networks and hence to develop traffic management measures for them. These methods have two distinct components: a traffic model, which represents the propagation of vehicles ...
