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 ...

A Protection-based Approach to QoS in Packet over Fiber Networks

Patrick Thiran

We propose a novel approach to Quality of Service, intended for IP over SONET (or IP over WDM) networks, that offers end-users the choice between two service classes defined according to their level of transmission protection. The first service class (call ...

Universal multimedia access from wired and wireless systems

Touradj Ebrahimi, Yousri Abdeljaoued

Personal computing and communication devices such as computers, personal digital assistants (PDAs), and mobile phones are moving to their next generation in which the end user will be able to access a multitude of information with a single device either lo ...

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 ...

Delay Jitter Bounds and Packet Scale Rate Guarantee for Expedited Forwarding

Jean-Yves Le Boudec

We consider the definition of the Expedited Forwarding Per-Hop Behaviour (EF PHB) as given in RFC 2598, and its impact on worst case end-to-end delay jitter. On one hand, the definition in RFC 2598 can be used to predict extremely low end-to-end delay jitt ...

IconoNET: a tool for automated bandwidth allocation planning

Christoph Frei, Boi Faltings, Pearl Pu Faltings

Communication networks are expected to offer a wide range of services to an increasingly large number of users, with a diverse range of quality of service. This calls for efficient control and management of these networks. In this paper, we address the pro ...

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 ...

A Min-Plus System Theory for Constrained Traffic Regulation and Dynamic Service Guarantees

Jean-Yves Le Boudec, Patrick Thiran

By extending the system theory under the (min,+)-algebra to the time varying setting, we solve the problem of constrained traffic regulation and develop a calculus for dynamic service guarantees. For a constrained traffic regulation problem with maximum to ...
