The new mechanism based on mobile agent is discussed and the core architecture called common agent request broker architecture (CARBA)is established to embody intelligent collaboration in the next generation open system. In order to evaluate whether CARBA is open system,ODP specification is used to validate the openness of CARBA.展开更多
文摘After the persistent practice in the 1990's,using "Open System" idea to integrate large scale computer systems has been the consenting fact.
