A generic interoperability testing framework and a systematic development process for automated interoperability testing

Interoperability is a prerequisite to allow users to access systems implemented by different vendors seamlessly. A good baseline to achieve interoperability is the implementation of a common set of standards. However, this is often not sufficient as different implementations of a standard are not necessarily interoperable. Therefore, different implementations of systems need to be assessed for interoperability by applying interoperability testing. In this article, we present a generic framework that enables automated interoperability testing with message checks, which assess the compliance of messages exchanged between systems. The goal of this framework is the provision of a basic functionality of interoperability test entities, the definition of a generic interoperability test environment, and guidelines for the specification of automated interoperability tests. The framework also considers aspects related to interoperability testing including verdicts, automation, and limitations of the system under test. Through the application of the framework, interoperability of systems can be assessed, systems can be validated, and standards can be improved. In addition, we present a systematic development process for automated interoperability tests to formalize the development and specification of an interoperability test system. We also consider aspects and critical issues, which are important for the development of a complete interoperability test system. The framework and the process are language and system technology independent. We present their application in a case study that includes interoperability tests for the Internet Protocol Multimedia Subsystem (IMS) using the Testing and Test Control Notation Version 3 (TTCN-3).     

Interoperability test suite derivation for communication protocols

This paper addresses the problem of interoperability testing for communication protocols. We develop a coherent framework of interoperability testing in which the notions of interoperability, interoperability testing, interoperability test case and interoperability test architecture are interrelated and a systematic interoperability test suite derivation method based on the framework. The approach to interoperability testing is illustrated with the example of the ATM Signaling Protocol. To demonstrate practicality of the approach, we implemented executable test suites derived by the method on a commercial ATM test platform, applied them for interoperability testing of various ATM equipment and analyzed the testing results.

模型驱动的嵌入式系统测试脚本生成方法研究与实现

自动化测试通过机器运行事先准备好的测试脚本进行测试，提升了软件测试效率。然而，测试脚本存在着编写专业性强、调试工作量大、维护成本高、难以复用等问题，成为自动化测试技术难以广泛使用的主要技术瓶颈。以嵌入式系统为测试对象，提出了模型驱动的测试脚本生成方法。该方法根据BPMN2.0建模标准对测试业务流程进行可视化建模；采用路径深度覆盖算法生成测试路径，根据路径上的约束条件生成测试输入参数；通过自定义的测试动作原语将测试路径和输入参数转化为可在嵌入式系统测试平台ETest上自动执行的测试脚本。实现的原型系统支持嵌入式系统的配置项级和系统级的测试脚本生成，提高了测试工具的易用性和测试模型及脚本的可理解性、可复用性和可维护性。

Columbia's VoD and Multimedia Research Testbed with Heterogeneous Network Support

This paper reports our progress in developing an advanced video-on-demand (VoD) testbed, which will be used to accommodate various multimedia research and applications such as Electronic News on Demand, Columbia's Video Course Network, and Digital Libraries. The testbed supports delivery of MPEG-2 audio/video stored as transport streams over various types of networks, e.g., ATM, Ethernet, and wireless. Both software and hardware video encoders/decoders are used in the testbed. A real-time video pump and a distributed application control protocol (MPEG-2's DSM-CC) have been incorporated. Hardware decoders and set-tops are being used to test wide-area video interoperability. Our VoD testbed also provides an advanced platform for implementing proof-of-concept prototypes of related research. Our current research focus covers video transmission with heterogeneous quality-of-service (QoS) provision, variable bitrate (VBR) traffic modeling, VBR server scheduling, video over Internet, and video transmission over IP-ATM hybrid networks. An important aim is to enhance interoperability. Accommodation of practical multimedia applications and interoperability testing with external VoD systems has also been undertaken.     

A federated approach to develop enterprise interoperability

Interoperability is one of the requisite features for existing enterprises in the increasing competitive and complex global market. In the last decade, enterprise interoperability has been developed and prescribed by various kinds of frameworks, methods, and techniques. However interoperability development is still not mature enough to become a science. Meanwhile, it keeps evolving according to different business requirement and market environment. Nowadays, networked environment causes unpredictable dynamical situations, thus sustainable interoperability becomes a new research dimension in the interoperability of enterprise systems and applications domain. In the sustainable interoperability, enterprise interoperability dynamics is one of the focal topics. This dynamic approach also called federated is originated from Enterprise Interoperability Framework of INTEROP NoE, which aims to establish interoperability on the fly. This paper presents current state on federated approaches to develop enterprise interoperability dynamics. Based on this study, a novel Federated interoperability approach is proposed. It aims at bridging the gap from interoperability concepts to the implementation of interoperable enterprise information systems development. This approach reuses distributed simulation interoperability concepts to facilitate and coordinate the communication between heterogeneous distributed information systems of the enterprises. This simulation part has been implemented into a software platform. This platform is complaint with the latest version of the high level architecture that is a distributed communication standard. This approach also proposes a development lifecycle that intends to reuse existing information systems without recoding them but by adapting them to the new requirements of interoperability dynamics.     

A formal method to real-time protocol interoperability testing

Interoperability testing is an important technique to ensure the quality of implementations of network communication protocol. In the next generation Internet protocol, real-time applications should be supported effectively. However, time constraints were not considered in the related studies of protocol interoperability testing, so existing interoperability testing methods are difficult to be applied in real-time protocol interoperability testing. In this paper, a formal method to real-time protocol interoperability testing is proposed. Firstly, a formal model CMpTIOA （communicating multi-port timed input output automata） is defined to specify the system under test （SUT） in real-time protocol interoperability testing; based on this model, timed interoperability relation is then defined. In order to check this relation, a test generation method is presented to generate a parameterized test behavior tree from SUT model; a mechanism of executability pre-determination is also integrated in the test generation method to alleviate state space explosion problem to some extent. The proposed theory and method are then applied in interoperability testing of IPv6 neighbor discovery protocol to show the feasibility of this method.
