DESCRIPTION:Distributed event-based systems are becoming increasingly popu
 lar as enabling technology for novel information-driven applications such 
 as transport information monitoring\, event-based supply chain management\
 , ubiquitous sensor-rich applications and the like. The latter\, however\,
  pose some serious performance and scalability challenges. In particular\,
  the inherent complexity and dynamics of such systems makes it difficult t
 o predict their behavior under load and ensure that enough resources are a
 vailable to meet the quality of service requirements. While many methods a
 nd techniques are available in the literature for workload characterizatio
 n and performance modeling of conventional distributed systems\, no method
 s have been proposed for distributed event-based systems. The latter have 
 several inherent properties that make their modeling rather challenging. I
 n this talk\, I will discuss an approach to performance modeling and evalu
 ation of distributed event-based systems. A practical method for workload 
 characterization and performance analysis using basic analytical technique
 s will be presented. It will be shown how more detailed performance models
  can be built to provide more accurate performance prediction.\n
