8、NATIONAL STANDARD ISO/IEC 9594-10 ITU-T RECOMMENDATION X.530 Information technology Open Systems Interconnection The Directory: Use of systems management for administration of the Directory Summary The Directory may support open systems applications such as message handling systems; file transfer, a

9、ccess and management (FTAM) systems; and transaction processing systems. Therefore, the Directory system may be manageable from an integrated system management platform. The purpose of Directory management is to assure that needed, accurate Directory information is available to users as scheduled wi

10、th the expected response time, integrity, security and level of consistency. Furthermore, systems management may be accomplished with the minimum burden on processing time and memory on platforms and the communications system. This Recommendation | International Standard describes the requirements f

11、or Directory management, and analyses these requirements to identify those that may be realized by OSI systems management services (and protocols), those that are realized by Directory services (and protocols), and those that are realized by local means. Source ITU-T Recommendation X.530 was approve

12、d on 13 November 2008 by ITU-T Study Group 17 (2009-2012) under ITU-T Recommendation A.8 procedure. An identical text is also published as ISO/IEC 9594-10. ii ITU-T Rec. X.530 (11/2008) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of

13、telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing te

14、lecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by th

15、e procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both

16、a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g. interoperability or applicability) and compliance with the Recommendation is achieved when all

17、of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGH

18、TS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU

19、 members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this m

X.530 (11/2008) Introduction This Recomm

27、endation | International Standard, together with other Recommendations | International Standards, has been produced to facilitate the interconnection of information processing systems to provide Directory services. A set of such systems, together with the Directory information that they hold, can be

28、 viewed as an integrated whole, called the Directory. The information held by the Directory, collectively known as the Directory Information Base (DIB), is typically used to facilitate communication between, with or about objects such as application entities, people, terminals and distribution lists

29、. The Directory plays a significant role in Open Systems Interconnection, whose aim is to allow, with a minimum of technical agreement outside of the interconnection standards themselves, the interconnection of information processing systems: from different manufacturers; under different managements

30、; of different levels of complexity; and of different ages. The purpose of Directory management is to assure that needed, accurate Directory information is available to users as scheduled with the expected response time, integrity, security and level of consistency. Furthermore, systems management m

31、ay be accomplished with the minimum burden on processing time and memory on platforms and the communications system. The Directory may support open systems applications such as message handling systems, File Transfer, Access and Management (FTAM) systems, and transaction processing systems. Therefor

32、e, the Directory system may be manageable from an integrated system management platform. This Recommendation | International Standard provides the foundation frameworks upon which industry profiles can be defined by other standards groups and industry forums. Many of the features defined as optional

33、 in these frameworks may be mandated for use in certain environments through profiles. This sixth edition technically revises and enhances, but does not replace, the fifth edition of this Recommendation | International Standard. Implementations may still claim conformance to the fifth edition. Howev

34、er, at some point, the fifth edition will not be supported (i.e., reported defects will no longer be resolved). It is recommended that implementations conform to this sixth edition as soon as possible. Annex A, which is an integral part of this Recommendation | International Standard, defines the ma

35、naged objects used for Directory System Agent administration. Annex B, which is not an integral part of this Recommendation | International Standard, lists the amendments and defect reports that have been incorporated to form this edition of this Recommendation | International Standard.

X.530 (11/2008) 1 INTERNATIONAL STANDARD ITU-T RECOMMENDATION Information technology Open Systems Interconnection The Directory: Use of systems management for administration of the Directory SECTION 1 GENERAL 1 Scope This Recommendation | International Standard describes the

37、requirements for Directory management, and analyses these requirements to identify those that may be realized by OSI Systems Management services (and protocols), those that are realized by Directory services (and protocols), and those that are realized by local means. Based on the requirements, this

38、 Directory Specification defines a model for Directory management that encompasses all of the requirements. Management of the Directory is divided into four major segments: a) management of the DIT Domain: Management of Directory information; b) management of the operation of a single DSA within a D

39、MD; c) management of the operation of a single DUA within a DMD; and d) management of the Directory Management Domain (DMD): Integrated management of the functional components of the Directory. This Recommendation | International Standard covers items a), b) and c). Item d), Management of the Direct

40、ory Management Domain, is for further study. Based on the model, this Recommendation | International Standard describes the detailed OSI Systems Management Managed Objects used to manage Directory System Agents (DSAs) and Directory User Agents (DUAs) within a Directory Domain, and describes the deta

41、iled OSI Systems Management Managed Objects used to manage the interfaces to DUAs and DSAs in other domains as shown in Figure 1. Figure 1 Scope of Directory management 2 Normative references The following Recommendations and International Standards contain provisions which, through reference in thi

42、s text, constitute provisions of this Recommendation | International Standard. At the time of publication, the editions indicated were valid. All Recommendations and Standards are subject to revision, and parties to agreements based on this Recommendation | International Standard are encouraged to i

43、nvestigate the possibility of applying the most recent edition of the Recommendations and Standards listed below.
