The Rodeo Group
Rodeo is a contrived acronym that stands for ``High speed networks,
open networks''. The main objective of the project is to design, implement,
and evaluate mechanisms for the efficient and flexible use of network resources.
To achieve the above objective, we focus our activities in three
main areas, namely:
This work is performed in relation with academic, research, and industrial
partners.
You will also find in this page a list of project
members and some additional information.
We also have a page in french.
Resource allocation and control
We are designing resource allocation mechanisms for both stateless networks
(such as the current Internet) and integrated networks. With stateless
networks, resource allocation is done using edge (i.e. end-to-end) mechanisms.
Our emphasis these past few years have been on mechanisms that integrate
multicast delivery, flexible flow and error control, etc. These mechanisms
are used in particular in the FreePhone Internet
telephony tool, in the Rendez-Vous videoconferencing
tool (successor of IVS, one of the first s/w videoconferencing
tool for the Internet) , and in the MiMaze
distributed game.
High performance architectures
Previous research in the group led to the development of the MAVROS
compiler, and of fast algorithms for the management of data transparency
in heterogeneous systems. We are extending this work so as to allow the
compiler to handle detailed specifications of the applications. This will
lead to further optimizations.
We expect the two research areas described above to eventually merge
within the framework of the Application Layer Framing (ALF) architecture.
It will then be possible to take into account specifications of an application,
of the network ressources required by the application, and to automatically
generate tailored communication modules that handle both data transparency,
synchronization, and transmission control for this application.
New Transmission Media
Our work is carried out over IP networks using a variety of underlying
technologies. Recently, we have carried out specific work on wireless links
(robust coding for wireless links), satellite links (routing over unidirectional
links, check out the UDLR page), and over ATM
links (specifically over the regional ATM testbed dubbed EuroSud155 - check
out experimental results).
Partners
Work on resource allocation and control is carried out in a variety of
projects and a variety of industrial, academic, and research partners.
Much of it revolves around the MERCI project
(a successor to the MICE
and MICE-2 projects) with University College London (UK), KTH (Sweden),
University of Oslo (Norway), GMD, RUS, and Teles (Germany).
Work on high performance architectures is carried out in collaboration
with University College London (UK), SICS (Sweden), and the University
of Technology of Sydney (Australia) within the HIPPARCH
project.
We are active in various working groups in the IETF
(Internet Engineering Task Force), in particular the AVT, UDLR, and
LSMA groups.
