The major goal of self-adaptive software is to provide a mechanism that allows a software system to dynamically change its architectural configuration during run-time to cope with requirement changes and unexpected conditions. Software which needs to handle dynamically changing internal and external environment is one of the areas in which self-adaptive software may do an important role in improving the reliability and performance of software systems. There are three main capabilities that are necessary to support self-adaptive software: the ability to monitor and recognize internal/external situations that affect behavior of the software system; the ability to determine when and what to reconfigure in the software system to handle the situations; and the ability to dynamically change the software architecture during run-time to make the reconfiguration effective. In this paper, we describe a software framework to support such capabilities to realize self-adaptive software and its experiment results.
