We provide an algebraic formalisation of connectors in <i>BIP</i>. These are used to structure <i>interactions</i> in a component-based system. A connector relates a set of typed ports. Types are used to describe different modes of synchronisation: rendezvous and broadcast, in particular.
Connectors on a set of ports <i>P</i> are modelled as terms of the… (More)

Comparison between different formalisms and models is often by flattening structure and reducing them to behaviorally equivalent models e.g., automaton and Turing machine. This leads to a notion of expressiveness which is not adequate for component-based systems where separation between behavior and coordination mechanisms is essential. The paper proposes a… (More)

The Algebra of Connectors AC(P) is used to model structured interactions in the BIP component framework. Its terms are connectors, relations describing synchronization constraints between the ports of component-based systems. Connectors are structured combinations of two basic synchronization protocols between ports: rendezvous and broadcast. In a previous… (More)

We develop a unified functional formalism for modelling complex systems, that is to say systems that are composed of a number of heterogeneous components, including typically software and physical devices. Our approach relies on non-standard analysis that allows us to model continuous time in a discrete way. Systems are defined as generalized Turing… (More)

We study glue operators used in component-based frameworks to obtain systems as the composition of atomic components described as labeled transition systems (LTS). Glue operators map tuples of LTS into LTS. They restrict the behavior of their arguments by performing memoryless coordination. In a previous paper, we have proposed a simple format for SOS rules… (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 discuss the challenges of building a simulation framework for hybrid systems, in particular the well-known Zeno effect and correct composition of models idealised by abstracting irrelevant behavioural details (e.g. the bounce dynamics of a bouncing ball or the process of fuse melting in an electrical circuit). We argue that the cornerstone of addressing… (More)

We consider two approaches for building component-based systems, which we call respectively architecture-based and architecture-agnostic. The former consists in describing coordination constraints in a purely declarative manner through parametrizable glue operators; it provides higher abstraction level and, consequently, stronger correctness by… (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)

— We consider several Hybrid ARQ (H-ARQ) control schemes for High Speed Downlink Packet Access (HSDPA) with 16 symbols Quadrature Amplitude Modulation (16QAM). These schemes consist of a sequence of values for the Xrv parameter to be used at sequential retransmissions when a block is not decoded correctly. A choice of an H-ARQ control scheme influences two… (More)
