Telecommunication Management Networks can be considered as a set of distributed objects interacting to perform the network monitoring and control functions.In this paper, we explore the way to a full object distribution based on the OMG CORBA principles. Some studies and the early results of the X/Open-NM Forum XoJIDM working group indicate that this is possible and promising for the future.We analysed, designed and implemented a full TMN Operation System based on CORBA object distribution. One of our main priority has been to preserve the interoperability with existing TMN components based on CMIP, taking advantage of the existing assets of information models defined with GDMO, that we kept as the specification language for interfaces between components. Specialized CORBA services offering TMN specific services have been defined using CORBA Common Object Services whenever that was possible.
