Description

RUN is involved in research and experimentation on multimedia group communication. Our current work focuses on transport protocols, intelligent middleware and active networking support for multicast congestion control.

In particular, we have designed a suitable multicast congestion control algorithm for layered video, called CIFL, and an Active Layered Multicast Adaptation Protocol (ALMA), that is built on top of an Active Network infrastructure. On the other hand, we designed a distributed algorithm, based on autonomous reflectors, that creates an active multicast tree on demand when the multicast connectivity is interrupted or nonexistent.

RUN is involved in the COST 264 European Action on "Enabling Networked Multimedia Group Communication".

Recently, this research has been supported by the Walloon Region in the TINTIN project. Earlier, RUN had been involved in the RACE CIO and ACTS ACCOPI projects, as well as in a Tournesol collaboration on this topic. In these projects, RUN has proposed a group communication framework, a multimedia multicast transport service, a QoS negociation scheme for multicast communication, and a group management service.
