IEEE, Piscataway, NJ, USA,98CB36158. p 445-454 CODEN: INOSE3 Publication Year: 1998 Abstract: Integration of management systems across techno- logical and administrative domain boundaries is a necessary prerequisite for automating or optimizing service manage- ment. Despite many years of standardization effort the num- ber of management technologies and interface specifications seems to continue to increase. An architectural approach to integrated network management, therefore, cannot be based on any single architecture or technology, but must instead be based on recognition of diversity and interoperability. The TMN-architecture is basically such an integration architec- ture, although OSI is sometimes assumed to be the only realization option. This paper presents experiences with the approach taken to realize integrated network management in Ž . the European ACTS project Prospect project number AC052 . Several layers of integration have been realized, including multi-vendor and inter-domain management, and several management technologies have been integrated, namely Ž . CORBA, OSI and SNMP.
