Test derivation methods suitable for interoperability testing of communication protocols were proposed in [1,2, 3] and applied to the TCP and the ATM protocols, The test cases that were generated by them deal with only the control part of the protocols. However, in real protocol testing, the test cases must manage the data part as well. For complete testing, in principle we must test all possible values of data part although it is impractical to do so. In this paper, we present a method generating the interoperability test suite for both the data part and the control part of protocols with the example of Tep connection establishment. In this process, we make use of experimental design techniques from industrial engineering to minimize the size of test suite while keeping testing capability. Experimental design techniques have been used for protocol confom1ance testing but not for intcruperability testing so far. We generate the test suite for data part by this method and show a possibility that we can test interoperability of protocols with the minimum number of test cases while maintaining the testing power.

WTO 체제의 출범에 따른 자유무역 강화 추이 및 시장개방에 따른 시장 경쟁강화와 더불어 오늘날 정보통신표준화는 그 동안 개발자 중심의 '기술 지향형 표준화'동으로부터 이용자의 서비스 욕구를 충족시킴으로써 시장 선점을 노리는 소위 '시장 지향형 표준화'동으로 그 방향이 전환되고 있다. 이러한 추세를 반영하여 최근 주요 선진국과 표준화기구에서는 '정보통신표준이 과연 정보통신 제품 및 서비스간의 상호운용성 Interoperability) 확보라는 본연의 목적을 제대로 달성시킬 수 있도록 충실히 작성 및 제정되었는가'는 차원에 보다 큰 관심을 가지게 되었다. 이에 본 고에서는 미국, 유럽, 일본 등의 주요 국가 및 표준화기구에서 추진되고 있는 정보통신표준의 상호운용성 관련 시험인증 정책을 분석하고, 이와 관련하여 향후에 중점적으로 다루어져야 할 주요 연구과제들을 살펴보았다.

컴퓨터 네트워크 발달로 다양한 통신 장비와 소프트웨어가 여러 제조업체에서 생산되고 있다. 그리하여 이들 서로 다른 구현물들의 적합성과 상호 운용성을 확인하는데 많은 시간과 비용이 소모되고 있다. 또한 장비 제조업체가 제공한 성능 결과는 제조사가 임의적으로 선정한 지표에 대한 측정값이므로 장비의 구매자와 사용자에게 혼돈을 줄 수 있다. 따라서 본 논문에서는 표준화된 시험 방법을 수행하기 위한 시험 지표와 시험 환경을 제시한다. 이는 장비 도입 시 기능과 성능 시험에 대한 유용한 분석 방안을 제공하고 분석에 소요되는 비용 절감 효과를 줄것이다.

Railway signaling system is the vital control system in charge of the core for safely train operation, its functional safety must be checked through sufficient verification. Until now, to verify the interoperability of developed railway signaling system, the on-site testing approaches have been applied after testing in laboratory with simulator. This approaches are some limited range of interoperable verification, so more systematic verification interoperability is required. In this paper, the three phases of interoperability verification for railway signaling system was proposed, and methodology for each phases are represented. And also The interoperability validation methodology and supported testing tool for railway signaling system is represented in this paper

Link-16 is a data link that provides joint interoperability to the US Navy, Air Force and NATO. Currently, the military relies entirely on foreign SW and tools for test environment, tactical simulation training and interoperability verification test for Link-16 operation. Therefore, it is necessary to develop Link-16 based operation environment test tool. In this paper, Link-16 network operational performance analysis simulator was developed by analyzing the function of Link-16 foreign tools. It also implements the SIMPLE standard interface for interworking with foreign SW and tools. The functional model for Link-16 network operation performance analysis consists of pre-analysis, real-time operational analysis, and post-analysis functional model. Each functional model test was performed through SIMPLE interworking with foreign SW and tools. Link-16 network operation performance analysis If we replace foreign SW through simulator, we can perform tactical training, network design verification and operation (scenario) verification for our military.
