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

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 (TMF) has provided 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 XML, Java and CORBA. 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.
