On-the-Fly Dependable Mediation between Heterogeneous Networked Systems

The development of next generation Future Internet systems must be capable to address complexity, heterogeneity, interdependency and, especially, evolution of loosely connected networked systems. The European project Connect addresses the challenging and ambitious topic of ensuring eternally functioning distributed and heterogeneous systems through on-the-fly synthesis of the Connectors through which they communicate. In this paper we focus on the Connect enablers that dynamically derive such connectors ensuring the required non-functional requirements via a framework to analyse and assess dependability and performance properties. We illustrate the adaptive approach under development integrating synthesis of Connectors, stochastic model-based analysis performed at design time and run-time monitoring. The proposed framework is illustrated on a case study.
