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 ...

The Renegotiable Variable Bit Rate Service: Characterisation and prototyping

Jean-Yves Le Boudec

he traffic generated by multimedia applications presents a high degree of burstiness that can hardly be described by a static set of traffic parameters. We present a dynamic QoS negotiation scheme applied to a prototype application that provides temporized ...

An example of dynamic QoS negotiation

The traffic generated by multimedia applications presents a high degree of burstiness that can be hardly described by a static set of traffic parameters. The following paper presents a dynamic QoS negotiation scheme applied to a video streaming application ...

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 ...

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 ...

Voice Service Interworking for PSTN and IP Networks

Jean-Pierre Hubaux

n recent years, the Internet has proven its ability to carry real-time data, including voice. Today, a small amount of voice traffic has already been diverted from the Public Switched Telephone Network (PSTN) to the Internet. If it expands, this phenomenon ...

Project DIANA - Converging and Integrating IP and ATM for real-time applications

The evolution of IP and ATM share some common drivers. Both of them are addressing efficient network resource utilisation. In order to evaluate the options and combinations offered by these technologies the DIANA project is looking into the areas where ATM ...

Quality of Service Renegotiations

Jean-Yves Le Boudec

Giving users simple access to QoS selection capability of ATM networks is important for the future of integrated services networks. We describe the first instance of an application in which users had the capacity to tune ATM traffic parameters with a butto ...
