Objective of the project
To provide a software networked architecture suitable for multimedia applications.
Users will have access to a set of multimedia services by way of a classical web browser. The architecture will securely download specific modules if needed by some applications. Moreover the middleware and transport layers will adapt to the network conditions to try and provide the best services at any time.
Project partners
- University of Liège (Research Unit in Networking - RUN)
- University of Louvain-la-Neuve (Telecommunication et Teledetection Unit - TELE)
Funding
The TINTIN project is supported by the Walloon Region.
Schedule
RUN started to work on this project on November 1st, 1998 until December 31st, 2001.
Role of RUN in the project
RUN studies intelligent middleware and transport protocols suitable for multimedia group communication, and especially for multicast congestion control and Quality of Service support. In particular, we have designed a suitable multicast congestion control algorithm for layered video.
We have also designed an Active Layered Multicast Adaptation Protocol (ALMA), that is built on top of an Active Network infrastructure. This scheme is being valided by simulations using the ns simulator. For that purpose, a simplified Execution Environment (EE) and NodeOS module have been implemented in ns.
This environment has also been used to design a distributed algorithm, based on autonomous reflectors, that creates an active multicast tree on demand when the multicast connectivity is interrupted or nonexistent.
