Support of multimedia services for distributed network training applications in CORBA-3

In this paper, fundamental technological issues in the implementation of today and tomorrow distributed network training systems are outlined. Given their highly distributed nature, the problems inherent to interoperability among heterogeneous systems are discussed. In this respect, the role of CORBA, an emerging standard for application integration technology, is presented. The limitations of today CORBA definition are discussed, and the extension of CORBA-3, with respect to the management of multimedia data (fundamental in the development of the next-generation distributed network training systems), is examined in more detail.
