Providing content-based services in a peer-to-peer environment Ginger Perng, Chenxi Wang, and Michael K. Reiter   View Paper (PDF)   Return to Short Presentations Abstract Information dissemination in a wide area network has recently garnered much attention. Two differing models, publish/subscribe and rendezvous-based multicast atop overlay networks, have immerged as the two leading approaches for this goal. Event-based publish/subscribe supports content-based services with powerful filtering capabilities; peer-to-peer rendezvous-based services allow for efficient communication in a dynamic network infrastructure. We describe Reach, a system that integrates these two approaches to provide efficient and scalable content-based services in a dynamic network setting. ©2005 Association for Computing Machinery
