  3. TMN defines principles and a management architecture which provides for interfacing a telecommunication network with computer systems in order to provide different management functions at different management levels M.301x states that ODP type principles may be needed in the design of TMNs ITU-T TMN

  4. CORBA is an object oriented framework designed to support a consistent programming model on a given platform and interoperability between different platforms CORBA allows applications to communicate irrespective of location, or design specifics Telecom Domain Task Force OMG Object Management Architecture

  14. CORBA at the X-Interface (SML) is seen as inevitable Studying the use of CORBA mechanisms for Q3 Interfaces at the Service Management layer ITU-T & T1M1

  15. Issue RFIs and RFPs for CORBA based technology relevant to the Telecommunications Industry. Management and control of A/V Streams CORBA/TMN Interworking Telecom Log Service Wireless Access & Control Notification Service Access to Telecommunication Service: Provisioning and Subscription Telecom Domain Task Force

  16. TMN applications can explicitly control association set-up while CORBA only has an Implicit Bind Model CORBA doesn't support making a single request to multiple objects at once. The client application has to make individual requests to all the objects involved Scalability and Performance CORBA Reservations

  17. TMN standards are: hard to use difficult to understand Skills are hard to find expensive TMN standards can take too long in the interm proprietary solutions become available TMN implementation is software based: future work on TMN should converge with the mainstream of the IT industry direction will increase the availability of TMN developers TMN Reservations

  18. CORBA has been used in many real applications for some time The continued design of CORBA based frameworks within development organisations will make specific requirements for standard services much clearer The JIDM Interaction Translation is not solely geared for the SML The JIDM Interaction Translation is bi-directional The RealTime SIG has the potential for implementation of CORBA Servers on the Managed Resource Conclusions
