Overview
ISO/IEC 10165-8:2000 is an international standard for information technology, focusing on the Open Systems Interconnection (OSI) reference model. Specifically, this part of the ISO/IEC 10165 series defines managed objects that support the upper layers of OSI - namely the application, presentation, and session layers. The standard provides a structured approach for representing, organizing, and managing these upper-layer elements through standardized managed objects, enabling effective network and systems management within multi-layered, open, and interoperable IT environments.
ISO/IEC 10165-8:2000 is essential for organizations that design, implement, or maintain systems based on OSI architecture. It ensures consistent management information representation and supports interoperability between different network management solutions by formalizing the structure and relationships of upper-layer managed objects.
Key Topics
-
Upper Layer Managed Object Model
Defines how upper layer objects, such as entities, protocol machines, service access points, and connections/associations, are represented and managed. It organizes these objects in hierarchical structures matching OSI’s session, presentation, and application layers.
-
Managed Object Classes
Specifies object classes for:
- Session Layer: session entities, session protocol machines, session SAPs, session connections, session subsystems
- Presentation Layer: presentation entities, presentation protocol machines, presentation SAPs, presentation connections, presentation subsystems
- Application Layer: application entities, application process invocations, ACSE (Association Control Service Element), ASO Entities, and their relationships
-
Inheritance and Containment
Presents object inheritance principles and how managed objects are contained within others. This provides a clear hierarchy for management and naming within the OSI model.
-
Relationships and Naming
Outlines how managed objects relate to each other, including naming conventions using relative distinguished names (RDNs), and attributes used to represent connections and associations between entities and subsystems.
-
Generic Definitions and Name Bindings
Describes generic managed object definitions and how name binding is used for structuring naming hierarchies in management information.
Applications
ISO/IEC 10165-8:2000 is widely applicable in environments where robust, standardized network and systems management is required. Key areas include:
-
Network Management Systems
Facilitates the monitoring, control, and configuration of protocol layers within managed networks. Enables consistent management across different OSI layers, improving operational efficiency.
-
Telecommunications Infrastructure
Supports large-scale telecom networks that operate using OSI protocols, allowing for effective management of upper-layer services in distributed environments.
-
Vendor Interoperability
Provides a common information model and managed object definitions, helping vendors implement interoperable network management systems and reducing integration complexities.
-
Standards-Based IT Solutions
Integral for organizations building or deploying solutions that rely on open systems, promoting compliance with international standards for information modeling and management.
Related Standards
ISO/IEC 10165-8:2000 is part of the larger ISO/IEC 10165 standards family, which collectively defines the structure of management information for OSI-based systems. Key related standards include:
In addition, many referenced ITU-T Recommendations such as X.200 (OSI Reference Model), X.283/X.284 (management information for network and transport layers), and X.701 (systems management overview) provide foundational concepts and models leveraged by ISO/IEC 10165-8.
