Complex and long-lived software need to be upgraded at runtime. Replacing a software component with a newer version is the basic evolution operation that has to be supported. It i...
Large, complex and long-lived software need to be upgraded at runtime. Addition, removal and replacement of a software component are the elementary evolution operations that have ...
Abstract. Many long-lived and distributed systems must remain available yet evolve over time, due to, e.g., bugfixes, feature extensions, or changing user requirements. To facilit...
In a component-based system components are basic computation units implementing specific business functions, and their interactions are explicitly represented by connectors. If th...
Abstract. Current trends in software development show a move towards supporting autonomous components (agents). The accurate timing of interactions between such components is growi...
