  • The most essential ROC(requirement operational capability) in order to assure the effectiveness of the C4I Systems in NCW Environments is the seamless and stable interoperability between systems. The U.S. Armed Forces that perceived the importance of interoperability, prepared the framework to apply from the proposal of requirement to every step of acquisition process. The Korea Joint Chiefs of Staff is also developing a similar system in order to assure the interoperability between command control(C4I) systems. In the paper, we specify the needs of standardization of test systems and international trends on the technology, and propose an interoperability test & evaluation system based on a standardization conformity method to improve the interoperability test & evaluation for the C4I systems in NCW environments. Finally we show an example of the implementation of the test system and its application to C4I systems to verify the proposed test system.

  • The major concern of component users who develop applications using the existing components is to confirm whether a component is collaborating with the different components in accordance with the requirements. Therefore, interoperability testing whose role is to check whether components collaborate with each other within the new operating environment not within the component development content of each component is considered as an importance research topic. In this paper, we propose a test case generation technique for interoperability test of component based software. The proposed technique defines a test model for generating test cases. The proposed technique generates test models from the use case specification and thereafter from these models, test cases for Interoperability testing are derived. In addition, we describe a tool which Implements the procedures for generating test sequences from test models.

  • Interoperability among defense information systems is one of the most important technologies in the modern information and electronic wars. Computer-aided interviewing has been used in popular for measuring the interoperability among information systems in military domain. In this paper, we suggest a new approach, testing after interviewing, in order to resolve the weakness of interviewing approach. In the testing after reviewing approach, the potential level of interoperability predicted by computer-aided interviewing is explored by distributed testing techniques. For this purpose, test requirements of each interoperability level are identified and appropriate testing model and test cases are suggested. Finally, a distributed testing tool is designed for automating the execution of suggested test cases.

  • In this paper, for the purpose of improving the future domestic train control systems and securing interoperability according to the global development trends of train control systems, we present the test results of interoperability between wayside train control system installed in existed line, and the onboard train control system. Due to the safety-critical characteristics of train systems, the site test in the section where the wayside equipment is installed, leads to a danger against safety. Therefore, by way of constructing a simulation environment of train control systems, we confirm the T/R data systems of the equipment for interoperability and test the interoperability by applying these systems to onboard equipment.

  • The importance of interoperability in modem warfare has been increasing ever since. Korean Ministry of National Defense has constructed and used the Systems Interoperability Test & Evaluation System in order to evaluate level of interoperability among defense information systems. However, as primary targets of SITES were information systems, there is limitation to be applied to weapon systems. This paper proposes an interoperability testing architecture and interoperability testing configuration items which encompass various aspects of interoperability testing. We developed a prototype which proved that the proposal can be realized and useful.

  • Middleware for mobile devices, embedded middleware, is used for mobile devices, cellular phone and DMB related services. It is essential for middleware providers to provide high quality middleware in conformity with its standard and interoperability on hardware platforms. The standard conformance and interoperability of embedded middleware are the key factors to make service providers succeed in their business. The quality of embedded middleware could be secured when Tests for the standard conformance and interoperability of embedded middleware are performed with well established test framework. In this paper, we describe middleware testing methodology of standard conformance, interoperability and middleware test framework for mobile devices.

  • QoS monitoring is a kind of real-time systems which allows each level of the system to track the ongoing QoS levels achieved by the lower network layers. For these systems, real-time communications between corresponding transport protocol objects is essential for their correct behavior. When two or more entities are employed to perform a certain task as in the case of communication protocols, the capability to do so is called interoperability and considered as the essential aspect of correctness of communication systems. This paper describes a formal approach on modeling and interoperability test case generation of a real-time QoS monitoring protocol. For this, we specify the behavior of flow monitoring of transport layer QoS protocol, i.e., METS protocol, which is proposed to address QoS from an end-to-end's point of view, based on QoS architecture model which includes ATM net work in lower layers. We use a real-time Input/Output finite State Machine to model the behavior of real-time flow monitoring over time. From the modeled real-time I/OFSM, we generate interoperability test cases to check the correctness of METS protocol's flow monitoring behaviors for two end systems. A new approach to efficient interoperability testing is described and the method of interoperability test cases generation is shown with the example of METS protocol's flow monitoring. The current TTCN is not appropriate for testing real-time and multimedia systems. Because test events in TTCN are for message-based system and not for stream-based systems, the real-time in TTCN can only be approximated. This paper also proposes the notation of real-time Abstract Test Suite by means of real-time extension of TTCN. This approach gives the advantages that only a few syntactical changes are necessary, and TTCN and real-time TTCN are compatible. This formal approach on interoperability testing can be applied to the real-time protocols related to IMT-2000, B-ISDN and real-time systems.

  • In this paper, for the purpose of improving the future domestic train control systems and securing interoperability according to the global development trends of train control systems, we present the test results of communication interfaces to verify the interoperability between CBTC wayside units tentatively installed in Bundang line that is one of the metropolitan area rail transit systems, and the CBTC onboard units developed through the national R/D project. The CBTC onboard equipment developed, has finished its installation and trial tests in the Bundang shunting yard. For the interoperability test, we should make an interface test with wayside equipment tentatively installed in Bundang line. Due to the safety-critical characteristics of train systems, the site test in the section where the wayside equipment is installed, leads to a danger against safety. Therefore, by way of constructing a simulation environment of train control systems, we confirm the T/R data systems of the equipment for interoperability and test the interoperability by applying these systems to developed CBTC onboard equipment.

  • The Systems Interoperability Test and Evaluation System(SITES) is an T&E support tool for both information system and weapon system. The SITES was developed by reference to the Level of Information Systems Interoperability(LISI) in US. We use the tool via MND Broad convergence Network(BCN) in order to assess information system's interoperability. Nowadays, there are many ongoing researches on expanding assessment capability into weapon systems. As part of those research topics, this paper analyze the characteristics of tactical data-link messages which is the way to exchange the information among the weapon systems, and reflect that characteristics in interoperability level assessment.

  • In the modern warfield, as the defense systems has been digitalized, intelligent, and working with network, the importance of interoperability among the systems has been also increasing. KMND(Korean Ministry of National Defense) has developed and used the SITES(Systems Interoperability Test & Evaluation System) based on Korean LISI(Levels of Information Systems Interoperability). SITES had been developed in order to evaluate the interoperability among information systems from the viewpoint of technical attributes. In this paper, we propose the extended interoperability evaluation model which can be applied not only the information systems, but also the weapon systems. Moreover, the extended interoperability evaluation model also includes the consideration of non-technical attributes.
