Abstract
In this talk, we present the work we are conducting at INRIA Rhône-Alpes on the design of component-based framework for the construction of autonomous systems.
Modern distributed computing systems are becoming increasingly complex. A major trend currently is to build autonomous systems, i.e. systems that reconfigure themselves upon occurrence of events such as software and hardware faults, performance degradation, etc. Building autonomous systems requires both a software technology allowing the development of administrable systems and the ability to build control loops in charge of regulating and optimizing the behavior of the managed system.
In this talk, we will mainly focus on the first requirement, i.e. providing a software technology for the development of administrable systems. We argue that better configurability can be reached through the use of component-based software frameworks. In particular, we present DREAM, a software framework for the construction of message-oriented middleware (MOMs). Several MOMs have been
developed in the past ten years. The research work has primarily focused on the support of various non functional properties like message ordering,reliability, security, scalability, etc. Less emphasis has been placed on MOM configurability. From the functional point of view, existing MOMs implement a fixed programming interface (API) that provides a fixed subset of asynchronous communication models (publish/subscribe, event/reaction, message queues, etc.). From the non-functional point of view, existing MOMs often
provide the same non-functional properties for all message exchanges, which reduces their performance. To overcome these limitations, we have developed DREAM (Dynamic REflective Asynchronous Middleware), a component framework for the construction of dynamically reconfigurable communication systems. The idea is to build a middleware as an assembly of interacting components, which can be
statically or dynamically configured to meet different design requirements or environment constraints. DREAM provides a component library and a set of tools to build, configure and deploy middleware implementing various communication paradigms. DREAM defines abstractions and provides tools for controlling the use of resources (i.e. messages and activities) within the middleware. Moreover, it builds upon the Fractal component model, which provides support for hierarchical and dynamic composition. DREAM has been successfully used for building various forms of communication middleware: publish-subscribe (JMS), total order group communication protocols, probabilistic broadcast,asynchronous RPC, etc.
