Design and implementation of an OSI conformance test system considering extensions for interconnectability testing

There is a wide perception of the need for conformance and interoperability testing to ensure the interoperability of open systems. In the circumstances, the authors have been making efforts to establish a system for interconnectability testing, which is a type of interoperability testing. In this paper, they discuss an interconnectability testing architecture that they have developed, and also a conformance testing system, named ACTS (AIC Conformance Test System), developed as the first step toward building an interconnectability testing system. ACTS is capable of extensions for an interconnectability testing system
