Описание (английский):

Refines the description of the application layer contained in the basic reference model for OSI (ITU-T Rec. X.200 / ISO/IEC 7498-1). Provides a framework for coordinating the development of existing and future application layer recommendations and standards. Is provided for reference by application layer recommendations and standards. The purpose is to facilitate a coherent and modular approach to the structuring of specifications for application layer behaviour.

Overview

ISO/IEC 9545:1994 - "Information technology - Open Systems Interconnection - Application Layer structure" refines and structures the Application Layer portion of the OSI Basic Reference Model (ITU‑T Rec. X.200 / ISO/IEC 7498‑1). The standard provides a formal framework for defining, composing and coordinating application-layer components so that application-layer recommendations and protocols can be developed in a coherent, modular and interoperable way.

Key topics and technical requirements

Application-Service-Object (ASO): Defines composite components used to structure the Application Layer. An ASO is built from one or more application-service-elements (ASEs), other ASOs, and a Control Function (CF) that coordinates component behavior.

Application-Service-Element (ASE): The indivisible protocol/function unit that handles a defined set of APDUs and procedures (the application-protocol among ASEs).

ASO-type / ASE-type: Type descriptions that specify the OSI-Service provided, referenced component types, and the CF required to coordinate components; these may be subjects of international standardization.

Control Function (CF): Mandatory part of an ASO-type that maps and coordinates OSI-Service primitives, presentation and transport usage, APDU concatenation/separation, transformations consistent with abstract syntax, and generation of APCI for interworking.

ASO-invocation (ASOI) and ASE-invocation (ASEI): Runtime instances representing specific uses of ASO/ASE capabilities; lifetimes are tied to the AE-invocation (AEI) and may be shorter than the parent AP‑invocation.

ASO-association / ASO-context: Defines cooperative relationships among ASOIs, the shared rules and state (enabled behavior, membership, lifetime, establishment and termination), and identifiers/tags used for unambiguous naming.

Application-association / Application-context: Special cases of ASO-associations and ASO-contexts that govern bilateral use of the Presentation Service and ACSE.

Naming and identification: Uses CCITT Rec. X.650 / ISO 7498‑3 naming principles with ASO‑qualifiers, ASOI‑identifiers and ASOI‑tags to unambiguously identify ASOs and ASOIs.

Practical applications

Provides a modular architecture for designing and documenting application-layer protocols and services (APDUs, APCIs, CF mappings).

Facilitates reuse and composition of ASEs and ASOs across multiple applications or profiles.

Guides implementers on lifetime, naming, association management and mapping to Presentation/OS1 services to achieve interoperable application-layer behavior.

Useful when modelling coordinated or concurrent use of multiple associations (e.g., continuation after association loss).

Who should use this standard

Standards developers and protocol designers defining OSI application-layer specifications.

Network architects and systems engineers implementing or integrating application-layer services.

Software engineers working on interoperability, middleware, and formal protocol composition.

Registries and organizations managing ASO/ASO-context naming and profiles.
