摘要：In static approach, a typical software update occurs by stopping a system to be updated by performing update of code and restarting the system. The system is not active during reconfiguration. The system gets to reboot when there is any updating made to the system. In this paper propose a Dynamic reconfiguration technique is introduced to maintain Quality of Service, which is meant to reduce application disruption during the system transformation. This dynamic reconfiguration technique involves the ability to change the system’s functionality or topology while the system is running. This technique involves safe dynamic reconfiguration such as insertion, removal and replacement of components. Our major challenge for this dynamic reconfiguration technique is to maintain the Quality of Service during system transformation, which is been achieved. The true benefit of this technique is application consistency and service continuity. The motivation for this dynamic reconfiguration technique is adaptability and high availability, which are both Quality of Service driven characteristics. An adaptive system is capable of runtime reconfiguration and works in unanticipated environments. In order to achieve high reliability and availability [3], the distributed component software has to support dynamic reconfiguration in order to avoid downtimes caused by rebooting the system.
