The evolution towards a higher-level managementrequires management information obtained from physicalto application elements as well as distinct resources(e.g., PC, UNIX workstations). This issue is difficult because the modeling of managementinformation is realized in many different ways and theinformation model integration represents an acutecurrent concern. In this paper we discuss thisintegration issue by specifying the sources of ManagementInformation Base (MIB) heterogeneity and identifyingtheoretical means characterizing approaches dealing withinformation models integration. Based on these results, the analysis of some existingintegration approaches led to dissatisfactions thusjustifying our contribution: integration guidelines andtheir implementation.

Still today, diagnosing a problem withmultimedia resources, such as video and sound cards, isinsufficiently automated. These resources thereforecannot be accurately managed. One reason for this is the lack of their thorough modeling. In this paper,we fulfill this need, by proposing a generic informationmodel, which we further apply to an MPEG2 video codec.We highlight the main characteristics of this kind of codec, identify parameters thatinfluence these characteristics, and reveal some of thetrade-offs that the application developer can considerin order to design efficient software for MPEG2 codecs. In addition to the benefits of this modelingfor the user and the application developer, we also showhow useful it could be for the providers of distributionservices, such as “live” video transmission. These providers can use our model to achieveresource management on an end-to-end basis.

The TINA (Telecommunications InformationNetworking Architecture) Network Resource InformationModel (NRIM) is a technology-independent network levelresource model that provides the foundation for the management and control of networks envisionedin the TINA architecture. Such networks are capable ofsupporting multimedia and multipoint communicationsessions and may consist of network elements based on different technologies. Different portionsof such networks will be under the control of differentnetwork administrations. NRIM describes such a networkabstractly in terms of network elements, aggregations of network elements, the topologicalrelationship between the elements, transport entities,and endpoints of transport entities. In addition, NRIMdefines management support objects for alarmsurveillance, resource configuration, and accounting. NRIM isindependent of the architecture of the individualmanagement functions. Further, the model is describedabstractly in terms of objects and relationships and it is independent of the protocols used forcommunication between management functions. Informationmodels for the management of specific networktechnologies can be derived from the generic modeldefined by the NRIM. This paper presents an overview ofthe NRIM emphasizing the recent advances made in theNRIM specification.

One of the main problems in GDMO is the lack ofadequate means to define the behavior of managedobjects. This paper reports the experiences that havebeen gained in the GDMO project, a joint project of Deutsche Telekom AG and the Institute forSoftware Technology, with formalizing actions andnotifications of a sample GDMO specification. It hasbeen investigated how different formal descriptiontechniques (FDTs), namely an object-oriented Z dialect andSDL, may be used to describe the semantics of actionsand notifications. However, the case study showed thatan integration of FDTs into GDMO is technically difficult and not very likely to improve theoverall quality of GDMO specifications.

The paper addresses the issue of time as anattribute of the network management information. Thetemporal dimension is incorporated in the managementinformation model proposed by the Internet Engineering Task Force (IETF), as it is described by theStructure of Management Information (SMI). The core ofthe proposed network management information model is theTemporal Management Information Base (TMIB), a conceptual representation of the diachronicbehavior of network resources. The temporal networkmodel also includes the definition of a specificarchitecture and a number of temporal services. Theexistence of such services facilitates the development oftime-reference applications in different functionalareas.
