9、TU-T Study Group 4 (1997-2000) and approved on 4 February 2000. An identical text is also published as ISO/IEC 10164-15. ii ITU-T X.746 (02/2000 E) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommun
10、ication 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 telecommunications on a worldwide basis. The World Telecommunication Standardization Confer
11、ence (WTSC), 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 the procedure laid down in WTSC Resolution 1. In some areas of information technology whi
12、ch 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 a telecommunication administration and a recognized operating agency. INTELLECTUAL PROP
13、ERTY RIGHTS 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 assert
14、ed by ITU 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, implementors are cautioned th

36、INTERCONNECTION SYSTEMS MANAGEMENT: SCHEDULING FUNCTION 1 Scope This Recommendation | International Standard defines the scheduling function. The scheduling function is a systems management function which may be used by an application process in a centralized or decentralized management environment
37、to exchange information and commands for the purpose of systems management, as defined by CCITT Rec. X.700 | ISO/IEC 7498-4. This Recommendation | International Standard is positioned in the application layer of ITU-T Rec. X.200 | ISO/IEC 7498-1 and is defined according to the model provided by ISO/
38、IEC 9545. The role of systems management functions is described by CCITT Rec. X.701 | ISO/IEC 10040. This Recommendation | International Standard: identifies a set of requirements satisfied by the function; provides a model for scheduling; specifies the management requirements of the function and ho
39、w these are realized by specification of managed objects and their behaviour; defines the conformance requirements to be met by implementations of this Recommendation | International Standard; defines managed objects. This Recommendation | International Standard does not define: the manner in which
40、management is to be accomplished by the user of the scheduling function; the nature of any implementation intended to provide the scheduling function; the nature of any interactions which result in the use of the scheduling function; the interactions which result by the simultaneous use of several m
41、anagement functions; the occasions where the use of the scheduling function is appropriate; the services necessary for the establishment, normal and abnormal release of a management association. 2 Normative references The following Recommendations and International Standards contain provisions which
