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.

With the rapid growth of network technology, two or more products from different vendors are integrated and interact with each other to perform a certain function in the latest systems. Thus. interoperability testing is considered as an essential aspect of correctness of integrated systems. Interoperability testing is to test the ability of software and hardware on different machines from different vendors to share data. Most of the researches model communication system behavior using EFSM(Extended Finite State Machines) and use EFSM as an input of test scenario generation algorithm. Actually, there are many studies on systematic and optimal test case generation algorithms using EFSM. But in these researches, the study for generating EFSM model which is a foundation of test scenario generation isn't sufficient. This study proposes an EFSM generating technique from informal requirement analysis document for more complete interoperability testing. and implements prototype of Test Case Generation Tool generating test cases semi-automatically. Also we describe theoretical base and algorithms applied to prototype implementation.

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.

Interoperability(lOP) is one of the major goal of Information Technology and Telecommunication fields. In this paper, we discuss dcvclOlJing an interoperabiiity testing(IOPT) method. As is easily gueOisecl from conformance testing and formal verification. state space explosion problem is the most serious problem we encounter in deriving interoperability test method and its test suite. A new state space reduction method to support interoperability testing is suggested based on Petri nets. The proposed test method can be applied to 1 to many communication protocols as well as 1 to 1 communication protocols efficiently

Recently, standardization organizations including ITU, ATM Forum, etc. have much interested in the interoperability issues between telecommunications products or services. Because interoperability issues are directly related to the improvement of qualities of telecommunications standards or services. Thus, this paper analyzes the trends of interoperability testing polices for quality improvement of telecommunications standards in major standardization organizations, for example ITU-T, ATM Forum, DAVIC, BC-lT 226(Europe), HATS Conference(Japan), including Korea. In addition this paper suggests the desirable national interoperability testing policies and directions for quality improvement of telecommunications standards or services.

Interest in conformance and the issues related to conformance and interoperability testing in ebXML products are rapidly gaining momentum among standards developers, implementers, and users. The goal is to obtain implementations of the standard that correctly perform the functionality specified in the standard. Conformance testing helps to achieve correct implementation. In this paper, we design and implement the CPP(Collaboration Protocol Profile)/CPA(Collaboration Protocol Agreement) and registry for ebXML conformance and interoperability testing tools that observe the standard specification in conformity with ebXML Message Service v2.0, ebXML Registry Service v2.0 and ebXML CPP/A v2.0.

In order to verify a digital substation based on IEC 61850, KEPRI in charge of POWER IT project related to SAS has constructed IED conformance testing system, which consists of HMI, IED (Intelligent Electronic Device), network equipment, V/I generator, and performed the interoperability test between two IEDs made by other vendors. The test was proceeded based on SCL and with system integrated tools

The testing tools implemented up to now for the LDAP(Light-weight Directory Access Protocol) interoperability tests are not easy to modify or add new test items since their source codes are not open. The object-oriented approach, therefore, is required to implement such a testing tool which can be easily modified or add new test items. Thus we designed the architecture for the testing tool applying the object-oriented approach. Java language, appropriate for the object-oriented approach, was used to implement the testing tool. The newly implemented testing tool can modify partly to adapt to the already stored data in the test suite information even during tests. Five LDAP servers can be tested simultaneously with the same configuration setup. Actual testing for the two LDAP servers validates the usefulness of the designed architecture with the proper working of the implemented testing tool according to the architecture.

Satellite image processing software should be able to support interoperability that is to enable consumers, citizens, large and small businesses and governments to make the fullest possible use of the world's spatial data and spatial processing resources. The goal of interoperability is to perform hands-on research, development, testing, fielding, and validation of potential and existing interoperable geoprocessing technologies. In this paper, component based architecture for fast interoperability is designed to maximize interoperability among the OpenGIS components specified in the OpenGIS abstract specifications and implementation specifications and to mix up the OpenGIS components and the fast access mechanism for high performance.

RFID applied in many area. I think that RFID enlarge for our life more and more. The application technology of RFID change the Mobile RFID using mobile phone and PDF etc. I think, Mobile RFID enlarge application technology gradually. In this paper, we propose the quality measurement metrics for mobile RFID middleware. I propose the quality testing model for interoperability and security of mobile RFID middleware. We examine the international standard for mobile RFID and software testing. In this paper, I proposed the evaluation model of mobile RFID middleware on the basis of international standard ISO/IEC 9126-2 and ISO/IEC 25000 series.
