“…These reconfiguration events capture the imperative quality of change while the system specification remains declarative. Others, such as the reconfiguration plans of Clipper [1] and the reconfiguration actions of Durra [3], describe a similar use of imperative commands in response to system events, though with less support for maintaining the integrity of the system than that which we propose.…”

Much of the recent work on Architecture Description Languages (ADL) has concentrated on specifying organisations of components and connectors which are static. When the ADL specification is used to drive system construction, then the structure of the resulting system in terms of its component instances and their interconnection is fixed. This paper examines ADL features which permit the description of dynamic software architectures in which the organisation of components and connectors may change during system execution.The paper outlines examples of language features which support dynamic structure. These examples are taken from Darwin, a language used to describe distributed system structure. An operational semantics for these features is presented in the n-calculus, together with a discussion of their advantages and limitations. The paper discusses some general approaches to dynamic architecture description suggested by these examples.

“…Thus, this mechanism presents some disadvantages making Poly lith unsuitable for the purpose of dynamic reconfiguration. The Durra programming environment [9] supports an event-triggered reconfiguration mechanism. Its disadvantage is that the reconfiguration treatment is introduced in the source code of the application and the programmer has to consider all possible execution events which may trigger a reconfiguration.…”

Abstract:Dynamic changes to an architecture is an active area of research within the software architecture community. Architectures must have the ability to react to events and perform architectural changes autonomously. In this paper, we focus on dynamic architectures reconfiguration. Our principle is to use the agent architectural concept to achieve this functionality with respect to some quality attributes. Hence the questions that we are currently facing: what are the architectural principles involved in building adaptable architecture? How should these architectures be evaluated? In addition, we adopt the B formal method to support design specifications for agent software architecture. Formal modeling of a specification of our agent software architecture enables us to analyze and reason about it ,with mathematical precision and aHows obtaining the abstract specification of the initial architecture formally. Besides, the design decisions are stored with the goal of making the reconfiguration tasks easier by the agent This paper describes work in progress and presents some interesting ideas connected to architectural agents.

“…A number of other systems provide a configuration language (Agnew 1994, Zimmermann 1994, Barbacci 1993, which have some similarities to Darwin but our approach is the only one to combine static initial configurations, dynamic preplanned reconfigurations and evolutionary or unplanned dynamic reconfigurations. We cater for configuration management of both 'closed' systems (i.e.…”

The paper describes the SysMan approach to interactive configuration management of distributed software components (objects). Domains are used to group objects to apply policy and for convenient naming of objects. Configuration Management involves using a domain browser to locate relevant objects within the domain service; creating new objects which form a distributed service; allocating these objects to physical nodes in the system and binding the interfaces of the objects to each other and to existing services. Dynamic reconfiguration of the objects forming a service can be accomplished using this tool. Authorisation policies specify which domains are accessible by which managers and which interfaces can be bound together.
