Overview
ISO/IEC 10165-4:1992 (identical to CCITT Recommendation X.722) provides guidelines for the definition of managed objects within the OSI systems management framework. It specifies how managed object classes should be documented and related to other OSI management Recommendations and International Standards. The standard is intended for any Recommendation or International Standard that defines management information to be transferred or manipulated by OSI management protocol (e.g., CMIP/CMIS) and the managed objects that represent that information.
Key Topics
- Scope and purpose: Ensures consistency and reusability of managed object class definitions and reduces duplication across working groups.
- Managed object class structure: Guidance on documenting attributes, attribute groups, operations (actions), notifications, behaviour and parameter definitions using standardized templates.
- Relationship to management protocol: Describes what protocol-related definitions are required so that managed object information can be transferred via CMIS/CMIP and encoded with ASN.1.
- Notational tools: Recommends notations (including ASN.1) and typefaces for expressing abstract syntax and data element structures.
- Inheritance and containment: Rules for inheritance (including multiple inheritance), specialization, and containment so that subclass characteristics and superclass definitions are handled consistently.
- Name binding and consistency rules: Emphasis on relationship integrity, including explicit rules for operations such as Delete - defining when deletion is permitted and how related objects and relationships are affected.
- Documentation structure: Recommended layout and templates for managed object class documentation; Annex A provides examples of guideline use.
Applications
- Standards authors creating or updating managed object definitions for OSI-based systems management.
- Protocol implementers and network equipment vendors mapping management information to CMIP/CMIS and ASN.1 encodings.
- Systems management architects and integration teams ensuring consistent managed object semantics across layers and products.
- Test and conformance teams preparing conformance statements and validation suites for managed object behaviour.
