Role of the partner

The INRIA team which will be involved in this project is the RODEO project. The objective of the RODEO project is the definition and the experimentation of communication protocols for very high speed networks, at one Gbit/s or more. This includes:

Within these activities, high speed application like multi-media messaging and conferencing are developed. They are conducted in cooperation with industrial partners (Esprit project THORN, OSI-95), and take into account the evolution of the communication standards.

The Esprit project THORN aimed at developing an X.500 compliant directory server. This project is now finished; our team was in charge of the conception and realization of the communication layers. Among the results obtained from this project and from follow-up developments, we find:

This work is still ongoing, in cooperation with industrial partners (Siemens-Nixdorf, E3X, BULL), in order to speed-up the ``presentation'' code generated by the ASN.1 compiler, and to use MAVROS as a ``stub-generator'' for distributed applications. Security extensions to the X.500 and X.400 services are being finalized within the Value project PASSWORD; the corresponding facilities (X.509, RSA) are being integrated in the MAVROS development environment.

The Esprit project OSI-95 aimed at developing a versatile high speed transport protocol. Our team was responsible within this project for the study of congestion avoidance algorithms suitable for high-speed ``real time'' connections, and for the evaluation of software implementations of the protocol. We developed a ``user level'' implementation of the XTP protocol, showing that its performance was equivalent to that of kernel implementations, and that the architecture allowed potential gains by using integrated layer processing techniques at the transport level. In order to evaluate the ``high speed'' applications requirements, we developed a ``video-conferencing'' software, based on the H.261 standard. This software is the basis for the ``work station video-conference'' workpackage of the Value project MICE.

Within this project, we will coordinate the work of the other partners within the project due to the experience we have, in both transport and application level control. We will specifically participate to the work on the application requirements and architecture definition. We share with LAAS the work concerning the Formal Description Techniques. Our participation to the early implementations and the results of the language definition task will serve as an input to the compiler building task for which we are responsible. We will also participate in the tests applications with the other partners.
