Full title and description

Information technology — Open Systems Interconnection — International Standardized Profiles: OSI Distributed Transaction Processing — Part 4: Support of Session, Presentation and ACSE PDUs. This part defines the expected support (status) for Session, Presentation and Association Control Service Element (ACSE) protocol data units (PDUs) for the distributed transaction processing profiles identified in ISO/IEC ISP 12061‑1.

Abstract

Specifies the status for the support of the Session, Presentation and ACSE protocols for the profiles identified in ISO/IEC ISP 12061‑1. The document indicates which PDUs and protocol features are required, optional or not applicable within the OSI distributed transaction processing profiles.

Scope

This part of ISO/IEC ISP 12061 defines, for the transaction‑processing profiles listed in ISO/IEC ISP 12061‑1, the required or recommended level of support for OSI Session, Presentation and ACSE PDUs. It is intended to clarify which protocol primitives and PDU types implementers and profile authors must support to achieve conformance and interoperability within OSI distributed transaction processing environments. The scope is focused on protocol‑level support statements rather than application semantics.

Key topics and requirements

• Specification of support status (required / optional / not applicable) for Session layer PDUs used by TP profiles.
• Specification of support status for Presentation layer PDUs (encoding/transfer syntax considerations relevant to transactions).
• Specification of support status for ACSE PDUs (association setup, release, and related service elements) within transaction profiles.
• Alignment of PDU support with the profile definitions given in ISO/IEC ISP 12061‑1 (profile tree and identifiers).
• Conformance guidance for implementers to ensure interoperable handling of Session/Presentation/ACSE functions in OSI distributed transaction processing.

Typical use and users

Target users were protocol implementers, system architects and integrators working on OSI‑based distributed transaction systems, standards bodies producing national/adopted versions of the profiles, and testing/interoperability laboratories. In practice this type of document was used during the 1990s by organisations implementing OSI TP and related profile stacks to ensure consistent handling of Session, Presentation and ACSE interactions.

FAQ

Q: What is this standard?

A: It is Part 4 of the ISO/IEC ISP 12061 series (1995) that specifies the required/support status for Session, Presentation and ACSE PDUs for OSI distributed transaction processing profiles.

Q: What does it cover?

A: It covers which Session, Presentation and ACSE protocol data units and features are required, optional or not applicable for the transaction processing profiles defined in ISO/IEC ISP 12061‑1, providing conformance guidance for those layers in an OSI TP environment.

Q: Who typically uses it?

A: Historically, protocol implementers, system architects, standards committees and interoperability/test labs working on OSI distributed transaction processing systems used this part to align implementations to a common set of PDU support expectations.

Q: Is it current or superseded?

A: The standard is withdrawn (not current). ISO lists the document as withdrawn; national catalogues indicate the series and its parts were removed from active status (withdrawal recorded in catalogues such as national standards bodies). One catalogue entry notes withdrawal from 19 May 2009.

Q: Is it part of a series?

A: Yes — it is Part 4 of the ISO/IEC ISP 12061 series (Parts 1 through 5), each addressing different protocol support aspects for OSI distributed transaction processing profiles.

Q: What are the key keywords?

A: OSI, Session, Presentation, ACSE, PDU, distributed transaction processing, ISO/IEC ISP 12061, conformance, profiles.
