Dependable distributed content-based publish/subscribe systems: doctoral symposium

Content-based publish/subscribe systems provide an efficient communication paradigm that allows decoupling of information producers and consumers across location and time. Distributed overlay-based publish/subscribe systems, while scalable, face many problems that hinders their applicability in scenarios requiring dependable communication. In this paper, we discuss three important dimensions of dependability in distributed content-based publish/subscribe systems, namely, availability, reliability and maintainability.
