2、ly “CCIlT Recommendation”) ITU-T RECMN*X-753 75 M 4862573 Ob35705 533 FOREWORD iW (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the iTU. Some 179 me

3、mber countries, 84 telecom operating entities, 145 scientific and industrial organizations and 38 international organizations participate in ITU-T which is the body which sets world telecommunications standards (Recommendations). The approval of Recommendations by the Members of ITU-T is covered by

4、the procedure laid down in WTSC Resolution No. 1 (Helsinki, 1993). In addition, the World Telecommunication Standardization Conference (WTSC), which meets every four years, approves Recommendations submitted to it and establishes the study programme for the following period. In some areas of informa

5、tion technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with IS0 and EC. The text of ITU-T Recommendation X.751 was approved on 21st of November 1995. The identical text is also published as ISO/IEC International Standard 10164-17. NOTE In this

6、 Recommendation, the expression “Administration” is used for conciseness to indicate both a telecommunication administration and a recognized private operating agency.

X.751(1995 E) Summary This Recommendation i International Standard provides a model for characterizing the relationship between resources in te

19、rms of the way one or more resources may provide a back-up role for other resources. This includes the hotkold standby concept and the associated aspects of primary and secondary back-up. The capability to manage the relationships is provided, for example, to allow a system to issue a request to ano

20、ther system to change over the resources acting in a back-up role or to change back. The relationships and requests are defined in terms of the managed objects representing the resources. Introduction This Recommendation I International Standard is developed according to ITU-T Rec. X.200 I ISOIEC 74

21、98-1 and ITU-T Rec. X.700 I ISO/IEC 7498-4. This Recommendation I International Standard is related to the following Recommendations I International Standards: - CCIIT Rec.

24、agement standardization inevitably involves coordinated work by a number of standards bodies. ITU-T SG 7 and ISOIEC JTCl/SC21/WG4 are jointly responsible for the development of Recommendations I International Standards that describe the architecture for OS1 management, the services, protocols and fu

25、nctions that are used for systems management, and the structure of management information. Other groups, in IT-T, ISOIEC JTCl/SC21, ISOIEC JTCl/SC6 and elsewhere, are responsible for the development of Recommendations I International Standards that describe the management aspects of particular layer

26、s of the OS1 Basic Reference Model; these may describe (N)-layer management protocols, management aspects of (N)-layer operation, and managed objects that provide a “management view” of aspects of the layer operation and are visible to systems management.

29、g one to one back-up relationships and specifies a set of generic definitions. It is positioned in the application layer of -T Rec.
