Peer-to-Peer and Online Gaming

The peer-to-peer paradigm has proved itself as a powerful approach for large-scale distributed systems. The construction of reliable and high-performance overlay networks is a young but fast moving research area. Our research focuses on the efficient management of data in and the quality of service in highly-dynamic and public peer-to-peer networks.

Current Projects

The BubbleStorm rendezvous search system for complex queries in large public overlays. The Channel-based Uni-directional Stream Protocol (CUSP). A novel transport protocol for P2P overlays and beyond. P2P-based communication infrastructure for Massively-Multiplayer Online Games (MMOGs). pSense: MMOG interest management with spatial publish/subscribe.
