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 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/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 how 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 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 management 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.
