Its main characteristics are: a precise, yet intuitive mathematical semantics based on categorical diagrams; a clear separation between computation, coordination, and distribution (including mobility); and a simple state-based language, inspired by Unity, to describe behaviour. This paper discusses the applicability of this approach to location-aware systems through the modelling of the GSM handover protocol, namely the way communication with a moving cellular phone passes from one station to another. The case study was developed with the Community Workbench, a tool that animates distributed and mobile architectural models.","PeriodicalId":262908,"journal":{"name":"Proceedings.

An important problem arises when there is more than one such self-management module: how can one make sure that they are composed to provide consistent and complementary benefits? In this paper we describe a solution that introduces a self-management coordination architecture and infrastructure to support such composition. We focus on the problem of coordinating self-configuring and self-healing capabilities, particularly with respect to global configuration and incremental repair. We illustrate the approach in the context of a self-managing video teleconference system that composes two preexisting adaptation modules to achieve synergistic benefits of both.","PeriodicalId":262908,"journal":{"name":"Proceedings.

Multiple, independent agencies, or \"partners\", cooperate to achieve their separate goals. Issues of trust are paramount for designers of such partners. While the research literature has produced a variety of trust technology building blocks, few have attempted to articulate how these various technologies can regularly be composed to meet trust goals. This paper presents a particular, event-based, architectural style, PACE, that shows where and how to incorporate various types of trust-related technologies within a partner, positions the technologies with respect to the rest of the application, allows variation in the underlying network model, and works in a dynamic setting. Initial experiments with variants of two sample decentralized applications developed in the PACE style reveal the virtues of dealing with all aspects of application structure and trust in a comprehensive fashion.","PeriodicalId":262908,"journal":{"name":"Proceedings.

These approaches aim at addressing performance issues as early as possible in order to reduce design failures. All of them try to adapt to software systems the well-known system performance analysis methodology. This implies that they assume at design time the availability of information about the hardware platform the software runs on. In recent years, we have proposed a methodology that allows quantitative reasoning on software aspects without considering hardware aspects. In this work, we extend our methodology to encompass a compositional approach to performance analysis of software architecture described by means of UML 2.0 diagrams. The main improvements include the characterization of architectural patterns and of their corresponding QNM pattern; the use of multi-chain queueing network as system target model and the identification of the information needed to parameterize the system model.","PeriodicalId":262908,"journal":{"name":"Proceedings.

Usually, in this evolution, several key components of the architecture are replaced. Achieving successful architecture evolution at a reasonable cost and effort is difficult. It requires many architectural and technological decisions. This paper describes an approach, called 3RDBA that facilitates replacing a key component in a long-living architecture. It is based on systematically gathering all information needed to make well-founded decisions regarding evolution of the architecture. The approach consists of an exploration, consolidation and migration cycle. Each cycle contains four steps: requirements, design, build and analyze. 3RDBA enables construction and evaluation of several alternative architecture realizations together with a migration path from the existing architecture towards the selected, new architecture. We describe how we have successfully applied this approach to support the evolution of a medical imaging system architecture.","PeriodicalId":262908,"journal":{"name":"Proceedings.

In many cases, central management and control of the network are far from trivial since both the topology and the connected devices change rapidly in such highly dynamic environments, while load circumstances may vary arbitrarily. The software architecture in a node needs to support flexibility. We have developed an architecture tailored to protocol stack software that allows customizing internal resource management in order to handle overload conditions gracefully. We show that the investment in explicit support for modularity and architectural constraints pays off: the paper elaborates on a case study in which dynamic adaptation of access control behavior leads to significant performance improvements.","PeriodicalId":262908,"journal":{"name":"Proceedings.
