36、s The objective of the present document is to provide guidance to those ETSI Working Groups producing TMN Management Information Models (MIM). It aims to: enable models developed by different groups to co-exist; assist in producing consistency across dels developed by different groups. The use of th

37、e guidelines is intended to produce Managed Object (MO) models that are implementable and reusable. It is therefore important to reuse the work of others and develop models in such a way that they can themselves be reused. It is intended that these modelling guidelines should be “Methodology Neutral

38、“. These guidelines assume that whenever possible and appmpriate, the ITU-T Recommendation X.700 4 Systems Management or ODMA Recommendations wiil be used as a basis of TMN managed object modelling. An overview of the relevant lTU-T Recommendation X.700 4 can be found in ETR 230 121 TMN Standardizat

39、ion Overview. The guidelines start by considering methods for requkments capture, they go on to consider Information and Dynamic Aspects of information modelling. The use of the NMP ensemble approach for documenting information models is considered, together with the use of Class libraries. This is

40、followed by a consideration of principles for GDMO implementation. Consideration of other protocols to be used in the evolving Testing the information model is considered to be outside the scope of these guidelines. is for further study. 5 Pre-Information Modelling Work 5.1 I nt roduction The develo

41、pment of Management Information Models is just one part of the activities involved in the definition and development of TMNs. There are several models of software system (waterfall, spiral) which distinguish between different activities. There is a consensus that eliciting and analysis of the needs

42、and constraints expressed by the procurers of the system is part of such activities. This activity can have names such are requirement capture, requirement definition to name but a few. If we consider management information modelling to be a specificatioddesign activity it is natural to thii that re

43、quirements related activity precedes it. This clause briefly discusses the requirement related activities which typically will take place, in part, at least prior to management information modelling in a TMN context. The origins of requirements on Th4N systems that drive the definition of informatio

44、n models are wide and varied. It is not appropriate to address such philosophical matters here. It is assumed that, at a point in the development of TMN systems or standards, the scope of a management problem is defied at a sufficient level of detail to allow the modelling of management information

45、as a set of managed objects.

46、 provide input to the management information modelling activity. These include: Definition of Management Services, etc. following ITU-T Recommendation M.3020 2. Definition of Management Functions, etc. following the Ensemble concept defined by NMP. Application of Open Distributed Processing (ODP) sy

The person modelling defines: Entities (Resources) that will be responsive to requests to engage in their magement. 0 Functions of people and machines which request entities to eng

48、age in management activity to achieve particular management goals. Typical entities are telephone exchange switches, cables for the transport of telephone traffic, counters representing the volume of traffic carried by a particular circuit, etc. It has been popular to categorize functions into those

49、 for configuration management, fault management, performance management, security management and accounting management. Management goals are states of the entities that the owners of the entities wish to estabiish and maintain. For example, a PNO running a particuiar network requires network equipment mis-operations to be unambiguously identified or a service subscriber wants to be notified of the duration of a service interruption affecting it. Before tackling a management information modelling task, available requirement statements should be
