IEEE, Piscataway, NJ,USA,98CB36158. p 445-454 CODEN: INOSE3Publication Year: 1998Abstract: Integration of management systems across techno-logical and administrative domain boundaries is a necessaryprerequisite for automating or optimizing service manage-ment. Despite many years of standardization effort the num-ber of management technologies and interface specificationsseems to continue to increase. An architectural approach tointegrated network management, therefore, cannot be basedon any single architecture or technology, but must instead bebased on recognition of diversity and interoperability. TheTMN-architecture is basically such an integration architec-ture, although OSI is sometimes assumed to be the onlyrealization option. This paper presents experiences with theapproach taken to realize integrated network management in

IEEE, Piscataway, NJ,USA,98CB36158. p 400-411 CODEN: INOSE3Publication Year: 1998Abstract: A research project dealing with the design and

Ž .implementation of a Q adapter function QAF , called man-agement gateway, is described for the integration of simple

Ž .network management protocol SNMP -managed resources inŽ .a telecommunication management network TMN environ-

ment. QAFs are a mechanism for bringing management infor-mation from the pre-TMN installed base of systems into aTMN environment. A TMN-compliant platform is chosen as

the core of the distributed management system because theopen systems interconnectionrTMN management architec-ture yields the largest set of management functionality. Onthe other hand, since SNMP agents have a widespread use, anintegrated management solution needs to take account of theInternet management framework. 27 Refs.

Open systems adhere to standards that letusers easily incorporate hardware and software from multiplevendors. The most commonly mentioned standards are foroperating systems; commercial platforms such as personalcomputers and workstations; commercial networks like Ether-net, transfer control protocolsrInternet protocols, and field-buses; and software models including object linking and em-

IEEE Comp Soc, Los Alamitos, CA, USA,97TB100234.p 405-414 CODEN: PHISD7 ISSN: 1060-3425Publication Year: 1997Abstract: In this paper we outline a semantic model for opendistributed systems which provides a foundation for a corre-sponding architecture description language. This semanticmodel is based on architecture models reported in left bracket2 right bracket left bracket 5 right bracket , with a number ofrefinements to support abstraction and composition. Themodel is specifically designed to describe open distributedsystems independent of implementation details such as com-munication protocols and middleware systems. The modelling
