Ilmstream: efficient multimedia streaming in decentralised distributed systems

Using the P2P-Model to implement multimedia streaming has been in the focus of research for some time. Many works have lead to very interesting results in the aspect of load balancing, caching and request scheduling. Only a few of the projects consider the decoupling of the neighbourhood relationship of the overlay network and the topology of the underlying infrastructure. In order to reduce the overall network load and to achieve point-to-point connections with better quality-of-service parameters we introduce ilmStream, a Peer-to-Peer Streaming System that forms geographical clusters of collaboratively streaming nodes.
