Roberto Baldoni, Roberto Beraldi, Leonardo Querzoni, Antonino Virgillito · 2004
In this paper, we outline an approach for enhancing content-based routing performance in publish/subscribe systems composed by an application-level network of event brokers. We present an algorithm which aim is to logically place close (in terms of TCP hops) brokers that manage subscribers with similar interests. We show how this algorithm allows the content-based routing algorithm to work in a favorable scenario, thus increasing its global performance.
