Distributed real-time objects: the ANSA approach

Object orientation, distributed computing and real time computing are well established research areas, but their integration are yet to be studied, because they seldom use compatible techniques. The paper reviews some experiences in the design, implementation and performance evaluation of two object based system environments for distributed real time applications. The two environments are based on the ANSA Open Distributed Processing architecture and its example implementation ANSAware. The focus of the article is the engineering mechanisms necessary to extend ANSAware to support real time computing.
