Design and implementation of Web Services-based NGOSS technology-specific architecture

摘要

To cope with frequent changes and functional additions of operation and support systems (OSSs), a guideline of OSS's architecture and development methods is needed. TeleManagement Forum has provided Next Generation Operations Systems and Software (NGOSS) technology-neutral architecture (TNA), which describes major concepts and architectural details of the NGOSS architecture in a technologically neutral manner. The TNA can be mapped onto technology-specific architectures (TSAs) using specific technologies such as Extensible Markup Language, Java, and Common Object Request Broker Architecture. Web Service, a distributed and service-oriented computing technology, can be also applied to NGOSS TSA. In this paper, we provide a design and implementation of Web Services-based TSA in accordance with the architectural principles of TNA and the performance evaluation of our proposed system. Our work can be used as a guideline for anyone planning to develop a Web Services-based NGOSS TSA.
