Test generation for the distributed test architecture

ISO (International Standardization Organization) developed the ISO distributed test architecture for testing layered protocols. Furthermore, a general distributed test architecture where the IUT (implementation under test) contains several distributed ports is used for testing distributed systems, based on the Open Distributing Processing (ODP) Basic Reference Model (BRM). In this architecture, the testers cannot communicate or synchronize with one another unless they communicate through the IUT; and no global clock is available in the system. This architecture could model a test architecture of a communication network with n accessing nodes, where the testers reside in these nodes. When n=2, this general distributed test architecture reduces to the ISO distributed test architecture. The authors develop a test selection method with respect to this general distributed test architecture.
