Abstract: A service-object-oriented dynamic evolution technology was proposed to facilitate application software’s dynamic adaptation requirement for the evolving Internet environment and variable user requirements. Under this mechanism, the variable parts were modeled into service-object, then the service registration and lookup mechanism referring to service-oriented computing were utilized to decouple the object reference for evolution. The evolution mechanism and evolution process were described in detail. Some contrasts were made among the representative research work. The experimental results show that the mechanism has better performance.
