tical transport technology and packet-based traffic to deliver services and earn revenue. TEMPo enables service providers to create and provision enhanced services that are focused on transforming optical capacity into services. The product has service shaping and monitoring capabilities, and business interfaces so that service OSS for Telecom Networks providers can create and deliver differentiated services. TEMPo draws on the serv- ice foundation classes of TN250G. Support for legacy service models and new serv- ice models eases service migration. 6.10.1 Product Overview TEMPo is offered in two versions: 1. TEMPo Network Center Edition is an application for device configuration, net- work topology management, service creation and provisioning, fault manage- ment and real-time statistics reporting. 2. TEMPo Operator Edition is a network management solution for smaller network environments. TEMPO Network Center Edition is a distributed, multi-user solution. It has a platform-independent management interface which provides GUI-based: device configuration service provisioning alarm management performance management SLA reporting. The distributed architecture utilises an RDBMS engine with a distributed client application. TEMPO Network Center Edition has historical data reporting and multiple con- current client support, which is essential for global service provider networks. The product has APIs, including CORBA and RMI, as northbound interfaces. These allow integration of end-to-end management services with existing customer OSS. Any network management and provisioning system involves the three architec- tural elements infrastructure and interfaces, domain and element management, and service creation and enhancement. 6.10.2 Infrastructure and Interfaces Database support is necessary, as the database contains the information about the network and the provisioned services. A database must be chosen to achieve per- formance, scalability and seamless integration with the rest of a service provider's OSS environment.
