A connector-based approach for controlled data distribution in RTP architecture

As the size and the complexity of software systems increases, a proper decomposition approach is strongly required, in particular to address issues about "when" and "how" distribution and elaboration have to be performed. In this paper we present RTP (Real Time Performers), a general-purpose architecture for the development of modular and configurable real-time distributed systems. It is based on basic and formally-modelled notions: projectors (data transferring components), state machines, command traces, topologies and strategists. The RTP decomposition approach is based on the component-connector pattern, refined with the specialization of the connector role. RTP rationale is the "externalization" and formalization of communication issues between components, with a strong separation between alignment mechanisms and policies.
