As bridging functional mismatches is frequently required, the use of adapters is unavoidable. In these cases an impact on the Quality of Service resulting from the adaptation is often undesired. Nevertheless, some adapters are deployed to change the Quality of Service on purpose when the interoperability problem results from mismatching Quality of Service. This emphasises the need of adequate prediction models for the impact of component adaptation on the Quality of Service characteristics. We present research on the impact of adaptation on the Quality of Service and focus on unresolved issues hindering effective predictions nowadays.","PeriodicalId":201701,"journal":{"name":"Obj.

Architecture Description Languages should be able to separate this concern and make it explicit. We propose to describe this coordination model as a set of specific components, which will be introduced into architectural connections to influence their behaviour. Two approaches are discussed: the first one defines reflection as a new architectural dimension, while the second one provides a conceptually simpler aspectual perspective. To show that these approaches are feasible, we provide an example using both techniques, where an initial pipeline-style architecture is extended by introducing a coordination infrastructure which encapsulates the classic Paxos consensus algorithm.","PeriodicalId":201701,"journal":{"name":"Obj.

Building a system from reusable or Commercial-Off-The-Shef (COTS) components introduces a set of problems, mainly related to compatibility and communication aspects. On one hand, components may have incompatible interaction behavior. On the other hand, it might be necessary to enhance the current communication protocol. We address these problems by means of our tool (called SYNTHESIS) which allows one both for preventing incompatible interactions and for enhancing the communication protocol by synthesizing a suitable coordinator. We have validated and applied SYNTHESIS for assembling Microsoft COM/DCOM components.","PeriodicalId":201701,"journal":{"name":"Obj.

This approach is based on a design pattern allowing the extension of systems by adding \"views\". Each view contains a set of elements in charge of a particular concern. At the same time, architecture description languages (ADL) improve the system understanding, its analysis and its prototyping. This work aims at closing these approaches to benefit from their respective advantages. Furthermore, we define an extension of Fractal component model to support views in a software architecture. With this extension, designers keep the traceability of entities and functions during the life cycle of their system. Besides, each user can manipulate a system with his own vision that is adapted to this requirement.","PeriodicalId":201701,"journal":{"name":"Obj.

Those are high level software components considered as autonomous in term of run-time. Our research field deals with several research domains: distributed systems, reuse, interoperability, components, model driven engineering. In this article, our proposal is a component metamodel, called Ugatze, allowing to reuse legacy components We present the conceptual level allowing to build component based system architectures, and the annotation level and its extra functional properties. A reuse process exploits those levels, building a conceptual model and exploiting annotation properties in order to perform an automatic integration. This process is supported by a model driven CASE tool. This article describes the metamodel, the process and the tool defined by the way of meta modelling standards.","PeriodicalId":201701,"journal":{"name":"Obj.

In addition, certain applications require that changes be applied dynamically without shutting down and restarting the application. In this paper we present an extension of classboxes to make them dynamic. A classbox is a kind of module that supports class extension (method addition and redefinition, and instance variable addition). Class extensions and definitions defined in a classbox represent an aspect. A classbox cross-cuts different classes by defining various extensions. In addition, with classboxes, aspects are dynamically applied to, removed from and hot-swapped in a system. Such aspects may crosscut a large number of classes which are extended by adding or redefining existing methods and adding new instance variables. Finally the aspects are scoped i.e., changes defined by a classbox are only visible inside this classbox and its clients.","PeriodicalId":201701,"journal":{"name":"Obj.
