Design and Implementation of Web Services-Based NGOSS Technology Specific Architecture

To scope 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.
