Research And Implement Of Dynamic Reconfiguration Of.NET Component

Dynamic reconfiguration allows a system to evolve from one configuration to another at run-time, while the system does not have to be taken off-line, rebooted to accommodate changes. Many important software systems must run continuously and cannt stop services at any time in most cases; therefore, dynamic reconfiguration is of great importance to these systems.This thesis analyses recent researches of dynamic reconfiguration in some articles; discusses the invocation problem between components which should be resolved by dynamic reconfiguration of component as well as the great impact to the system introduced by dynamic reconfiguration; designs and implements a framework prototype which supports dynamic reconfiguration of component in .NET, validates the correctness of the prototype and tests the performance of the prototype. The dynamic reconfiguration framework designed in this thesis monitors the invocations between components through interceptors and blocks the invocations through interceptors, as a result drives the component to a reconfigurable state effectively, which is the main feature of the thesis. By blocking the invocations between target component and other components, allowing ongoing invocations between target component and other components to complete, the consistency of the components is guaranteed.
