With the gradual adoption of publish/subscribe systems in mission critical areas, it is essential that systems are subjected to rigorous performance analysis before they are put into production. However , existing approaches to performance modeling and analysis of pub-lish/subscribe systems suffer from many limitations that seriously constrain their(More)
Publish/subscribe systems are used increasingly often as a communication mechanism in loosely-coupled distributed applications. With their gradual adoption in mission critical areas, it is essential that systems are subjected to a rigorous performance analysis before they are put into production. However, existing approaches to performance modeling and(More)
Rendering networks and distributed systems self-managing and self-optimizing has become a major research focus. This task is especially important for systems, such as publish/subscribe systems, that are used in dynamic environments. In these settings, a static configuration usually leads to a largely suboptimal system performance, while manual optimization(More)
In this paper, we present a distributed algorithm that autonomously adapts the routing configuration in a broker overlay network to dynamically optimize the system. The possibility of adaptation arises from a new kind of routing algorithms, called hybrid routing algorithms, that combine the usage of different routing algorithms in one overlay network. The(More)
