Worst Case Burstiness Increase due to FIFO Multiplexing

Jean-Yves Le Boudec, Juan Echagüe

We consider a FIFO multiplexer fed by flows that are individually constrained by arrival curves, and look for the best possible arrival curve for every output flow. This problem arises in scenarios where aggregate multiplexing is performed, such as differe ...

Joint Smoothing and Source Rate Selection for Guaranteed Service Networks

Pascal Frossard, Jean-Yves Le Boudec, Olivier Verscheure

We consider the transmission of variable bit rate (VBR) video over a network offering a guaranteed service such as ATM VBR or the guaranteed service of the IETF. The guaranteed service requires that the flow accepted by the network has to be conforming wit ...

Broadcast quality video over IP

We consider the problem of designing systems for the transmission of high-quality video signals over certain high-speed segments of the public IP network. Our most important contribution is the definition of a network/coder interface for IP networks which ...

High-bandwidth internet video telephony

Martin Vetterli

We consider the problem of full-duplex video transmission over the Internet, under real-time delay constraints. In this work we present the design of a complete communications system, whose salient features are: (a) a soft real-time transport protocol, who ...

User-Oriented QoS Analysis in MPEG-2 Video Delivery

Pascal Frossard

We address the problem of video quality prediction and control for high-resolution video transmitted over lossy packet networks. In packet video, the bitstream flows through several subsystems (coder, network, decoder); each of them can impair the informat ...

Renegotiable VBR service

In this work we address the problem of supporting the QoS requirements for applications while efficiently allocating the network resources. We analyse this problem at the source node where the traffic profile is negotiated with the network and the traffic ...

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 ...

Circuit Emulation over IP Networks

Jean-Pierre Hubaux

The best-effort service offered by the Internet is not suitable for a large variety of multimedia applications, which require strict guarantees on losses and end-to-end delay. We design functionalities and mechanisms for RTP in order to provide a transport ...
