An ATM transport network operation system based on TMN

The ATM transport network operation system described follows the TMN concept and supports CMIS/P interfaces to connect its subsystems. It contains about a hundred GDMO object classes, which were specially designed to achieve the operation system function. New technologies introduced to ensure effective and rapid system implementation include a directory system, to solve the problem of object instance location, and the use of GDMO object classes to design all system functions. In addition, an original common software platform is used to support the GDMO object intercommunication function. This operation system achieves a distributed object processing environment that supports CMIS/P interfaces. The system has been deployed in Japan and is now being used in multimedia experiments, the initial results of which are encouraging.
