摘要: This paper develops content-based publish/subscribe algorithms to support general overlay topologies, as opposed traditional acyclic or tree-based topologies. Among other benefits, publication routes can adapt dynamic conditions by choosing among alternate routing paths, and composite events be detected at optimal points in the network. The are implemented PADRES system evaluated a controlled local environment wide-area PlanetLab deployment. Atomic subscription notification delivery time improves 20% well connected network, subscriptions processed with 80% less network traffic notifications delivered about half end delay.
