The
French-developed Internet protocol, officially recognized as RFC 3077,
meets the rigorous International Engineering Task Force (IETF) eligibility
requirements.
April 12, 2001
The UDLR protocol is the result of research work carried out in Sophia-Antipolis, France, by the RODEO/Planète project team from INRIA (the French National Institute for Research in Computer Science and Control). This research project, managed by Scientific Director Walid Dabbous, was dedicated to high-speed networks, and its main players were Emmanuel Duros, who concentrated his efforts on UDLR, and Patrick Cipière.
The UDLR protocol is a standard mechanism which enables bidirectional satellite communications using all the existing types of return channel technologies (RTC, ADSL, RNIS, Ethernet and Satellite), while supporting all standard Internet protocols (IP, TCP, UDP etc.).
"This solution is a simple modification with a major impact on the implementation of Internet via satellite. Its new status of proposed standard will encourage more hardware manufacturers to ensure that their equipment supports this protocol."
Walid Dabbous, INRIA RODEO/Planète Project Leader
INRIA successfully implemented and tested UDLR using a satellite link. The further implementation of services using this technology was then examined by Luc Ottavj, UDcast Chief Scientist Officer.
The award of the RFC 3077 (Request For Comment) is major milestone for French network research. This Internet protocol, the brainchild of INRIA scientists, has enjoyed further technical and commercial development thanks to the creation of UDcast, and gained the recognition of the IETF (International Engineering Task Force) following a long process of validation by the international scientific community.
"The development of the UDLR protocol is central to UDcast's activity and, as early as June 2000, Emmanuel Duros chose to become involved in this major corporate project. We developed a complete range of software in order to give INRIA's scientific research the concrete expression we felt it so richly deserved."
Didier Tymen, UDcast CEO
UDcast was created in June 2000 by Didier Tymen and four INRIA engineers and researchers who developed and implemented UDLR technology: Emmanuel Duros, Luc Ottavj, Patrick Cipière and Antoine Clerget.
INRIA aims to network skills and talents from the fields of information and computer science and technology from the entire French research system. This network allows scientific excellence to be used for technological progress, for creating employment and wealth and for new uses in response to socio-economic needs. INRIA's decentralized organization (5 Research Units), its small autonomous teams, and regular evaluation enable INRIA to develop its partnerships, with 47 research projects out of 87 shared with universities, Grandes Ecoles and research organizations. It is also strengthening its involvement in the development of research results and technology transfer: 600 R & D contracts with industry and 40 technology companies have been born of the Institute.
