phase was demonstrated at the Telemanagement World Conference in Nice, May 2001. 10 Network Inventory Management inter-service provider business models with associated changes of information exchanged in a business-to-business environment. The leader of the project opined that it was challenging to offer multi-layer, multi-carrier VPN services and this was largely because there were few or not any OSS which could deal with this environ- ment without swivel-chair integration and telephone calls or e-mails between dif- ferent sites of different carriers. While consuming resources, this also limited the opportunities for growth and differentiation. The project sought to deliver to service providers a more complete utilization of network inventory management. The project used TM Forum NGOSS concepts for the development of integrated OSS. The project also quantified the use of the TMF's NGOSS plug-and-play framework to reduce time to market for new services in a realistic environment and addressed the additional issues, including security and scalability. 10.10.1 Netscient Netscient's N-Center is an object-oriented network planning and inventory man- agement solution.
