Dynamic architectures in which interactions between components can evolve during execution, are essential for modern computing systems such as web-based systems, reconfigurable middleware, wireless sensor networks and fault-tolerant systems. Currently, we lack rigorous frameworks for their model-ing, development and implementation. We propose Dy-BIP a(More)
—The identification of Internet applications is important for ISPs and network administrators to protect the network from unwanted traffic and prioritize some major applications. Statistical methods are widely used since they allow to classify applications according to their statistical signatures. They combine the statistical analysis of flow parameters,(More)
Although distributed systems are widely used nowadays, their implementation and deployment is still a time-consuming, error-prone, and hardly predictive task. In this paper, we propose a methodology for producing automatically efficient and correct-by-construction distributed implementations by starting from a high-level model of the application software in(More)
Behavior, Interaction, Priorities (BIP) is a component framework for constructing systems from a set of atomic components by using two kinds of composition operators: interactions and priorities. In this paper, we present a method that transforms the interactions of a component-based program in BIP and generates a functionally equivalent program. The method(More)

Verification of component-based systems still suffers from limitations such as state space explosion since a large number of different components may interact in an heterogeneous environment. Those limitations entail the need for complementary verification methods such as runtime verification based on dynamic analysis and prone to scalability. In this(More)
Architectures depict design principles: paradigms that can be understood by all, allow thinking on a higher plane and avoiding low-level mistakes. They provide means for ensuring correctness by construction by enforcing global properties characterizing the coordination between components. An architecture can be considered as an operator A that, applied to a(More)
We propose two expressive and complementary techniques for the verification of safety properties of infinite-state BIP models. Both our techniques deal with the full BIP specification, while the existing approaches impose considerable restrictions: they either verify finite-state systems or they do not handle the transfer of data on the interactions and(More)
