Dependence management for dynamic reconfiguration of component-based distributed systems

The growing popularity of wired and wireless Internet requires distributed systems to be more flexible, adaptive and easily extensible. Dynamic reconfiguration of component-based distributed systems is one possible solution to meet these demands. However, there are some challenges for building dynamically reconfigurable distributed systems. Managing dependencies among components is one of the most crucial problems we have to solve before a system can be dynamically reconfigured at runtime. This paper describes a dependence management for dynamic reconfiguration of distributed systems. The dependence management analyzes not only the static dependencies among components, but also the dynamic dependencies that take place at runtime, in order to support an efficient consistent reconfiguration of distributed systems. In addition, the dependence management can deal with nested dependencies during a dynamic reconfiguration.
