9、rdization Sector (IT-T) is a permanent organ of the ITU. The IT-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Conference (WT

10、SC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics. The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1. In some areas of in

11、formation technology which fall within IT-Ts purview, the necessary standards are prepared on a collaborative basis with IS0 and IEC.

21、MENDATION INFORMATION TECHNOLOGY - OPEN DISTRIBUTED MANAGEMENT ARCHITECTURE 1 Scope This Recommendation I Intemational Standard describes the Open Distributed Management Architecture (ODMA). ODMA provides an architecture for the specification and development both of systems management as an open dis

22、tributed application and of the management of open distributed applications. ODMA also provides the architectural fiamework for the development of the standards needed within the architecture. The management will be of a distributed nature; this implies: - - - distribution of the managing activity;

23、management of distributed applications; and management of resources that may be distributed. ODMA is compliant with the ODP-RM, so that in a distributed environment OS1 Systems Management can be used in combination with other techniques that are engineered and implemented according to ODP principles

24、. This Recommendation I International Standard is the base document of a (potential) range of standards and Recommendations to be developed within ODMA. Figure 1 provides an overview of the relationship between this Recommendation I Intemational Standard and other standards. Other standards that may

25、 be developed within ODMA are: - ODMA supports: Based on the General Framework of ODMA, these standards give descriptions of specific systems support of ODMA. For example, the OS1 Systems Management and COMA support of ODMA have been identified. ODMA viewpoint notations: These component standards pr

26、ovide standardised notations for describing the ODP viewpoints for ODMA (see for example Annex D). These notations are described in separate documents for the ODMA viewpoint notations. ODMA functions: These component standards describe functions that are necessary for the construction of an Open Dis

27、tributed Management System. Some example functions like the operation dispatcher function or the notification dispatcher function are outlined in this Recommendation I Intemational Standard. - - - ODMA inter-domain functions: These component standards describe the intenvorking between different para

28、digms providing support for ODMA, for example, between OS1 Systems Management and COBA. As illustrated in Figure 1 this Recommendation I International Standard only elaborates a subset of supporting ODMA systems but allows for developments of other clauses. As a consequence, this Recommendation I In

29、temational Standard consists of two sections: 1) General Framework This clause describes ODMA as a specific interpretation of the Reference Model of Open Distributed Processing for the purpose of management. It introduces general terms that are needed for open distributed management. It may also ide

30、ntifj tools for the description of the open distributed management applications. OS1 management support for ODMA This clause describes the OS1 management support for ODMA. It relates the current OS1 systems management concepts to ODMA concepts. However, it extends the current systems management stan

31、dards to support the distribution of the management activities and the distribution of resources to be managed. As this specific interpretation reflects the current OS1 standards, limitations may be imposed. For instance, only a number of distribution transparencies may be supported by the (extended

32、) OS1 management mechanisms. 2) ITU-T Rec.
