Abstract

The main objective of the project is to design, implement, and evaluate mechanisms that will allow the efficient and flexible use of high-speed networks (with a bandwidth layer than 1 Gbps).

To achieve the above objective, we focus our activities in 2 main areas, namely:

-

Transmission control protocols for high-speed networks.
We are designing and developing flexible and high performance transmission control protocols which integrate mechanisms for the allocation of resources in the network, for multicast delivery, for flexible error control, etc... These protocols are used in particular in an audio application (FreePhone), a video application (RendezVous) and a distributed game application (MiMaze) over the Internet, developed within the project.

-

High performance applications.
We are designing and developing compiler based techniques to the automatic generation of efficient communication code tailored to the needs of distributed applications.

We expect the two research areas described above to eventually merge within the framework of the recently-proposed Application Level Framing (ALF) architecture. It will then be possible to take into account specifications of an application, of the network resources required by the application, and to automatically generate tailored communication modules that handle both data transparency, synchronization and/or transmission control for this application.

These activities are done in the collaboration within french, european and international projects. The activities on transmission control led to several industrial cooperations, in particular in the context of the european projects MICE/MERCI (with UCL, GMD, KTH and UiO), with the CNET, and with BULL. The activities on high performance applications are done in the context of the IT LTR project HIPPARCH (with UCL, SICS, UTS and Dassault Electronique). Recent industrial collaborations aim at extending our work to new transmission media. In the context of a collaboration with Eutelsat, we study the transmission of the Internet trafic over unidirectional links, for example satellite links with terrestrial feedback. We also collaborate to network protocols and multimedia applications standardization actions in the context of the Internet Engineering Task Force.
