A TMN (Telecommunication Management Network) is a management architecture framework which provides an environment for interfacing a telecommunication network with computer systems in order to provide different management functions at several different levels. The ITU-T X.700 series of standards (also known as OSI network and systems management standards) are developed to manage networks and network elements in a TMN environment. Many efforts have been made to define managed objects and develop management platforms for telecommunication network management.
CORBA technology, on the other hand, provides a distributed object computing environment. It provides a basic framework for distributed object management and is capable of supporting global multivendor networks. Its distributed nature, object orientation, and the ability to handle complex objects makes it a candidate technology for telecommunication service management.
