Full title and description

Road vehicles — In-vehicle Ethernet — Part 11: Application layer to session layer conformance test plans. This International Standard specifies conformance test plans (CTP) for the application, presentation and session layers of in-vehicle Ethernet implementations, presented as a collection of test cases intended for evaluation of electronic control units (ECUs).

Abstract

This standard defines application/presentation/session layer conformance test cases for in-vehicle Ethernet ECUs, including scalable Service-Oriented MiddlewarE over Internet Protocol (SOME/IP) and Dynamic Host Configuration Protocol (DHCP) version 4 test cases, with test descriptions, preconditions and expected results to support manufacturer quality-control and conformance verification activities.

Scope

The standard provides conformance test plans covering the OSI application, presentation and session layers for in-vehicle Ethernet ECUs. It is intended as a reference collection of recommended test cases that car manufacturers and their suppliers can use within quality control and conformance verification processes; the document specifically includes test case sets for SOME/IP and DHCPv4 among the application-layer protocols addressed.

Key topics and requirements

• Definition and structure of conformance test plans (CTP) for application/presentation/session layers.
• SOME/IP protocol conformance test cases (message formatting, service discovery, serialization/transport behaviors).
• DHCPv4 client/server conformance test cases relevant to in-vehicle networks.
• Test preconditions, test steps, expected results and pass/fail criteria for each test case.
• Guidance for test environment, ECU configuration and interoperability considerations for automotive use.

Typical use and users

Used by automobile manufacturers, ECU and component suppliers, independent test laboratories, tool vendors that implement conformance test suites, and integration/QA teams to verify that ECU implementations of in-vehicle Ethernet application-layer protocols meet the specified conformance requirements. The standard is intended to be referenced in vehicle supplier quality and verification processes.

FAQ

Q: What is this standard?

A: An ISO International Standard (ISO 21111-11:2021) that specifies conformance test plans for the application, presentation and session layers of in-vehicle Ethernet implementations, targeted at ECUs.

Q: What does it cover?

A: It covers a collection of conformance test cases (CTPs) for application/presentation/session layer behaviors, including explicit test sets for SOME/IP and DHCPv4, with test descriptions, preconditions and expected outcomes to support manufacturer testing and verification.

Q: Who typically uses it?

A: Automobile OEMs, ECU suppliers, test laboratories, conformance/tool vendors and integration/QA teams who need standardized test cases for verifying in-vehicle Ethernet application-layer protocol implementations.

Q: Is it current or superseded?

A: This document was published in December 2021 and is listed as Published in the ISO catalogue; there is no ISO listing indicating it has been withdrawn or superseded as of its bibliographic entry. Users should check the ISO catalogue or national standards bodies for the most recent status before relying on it for certification.

Q: Is it part of a series?

A: Yes — it is part of the ISO 21111 series for in-vehicle Ethernet; ISO 21111-1 provides general information and definitions for the series and other parts (for example ISO 21111-10) cover lower OSI layers and related conformance test plans.

Q: What are the key keywords?

A: In-vehicle Ethernet, SOME/IP, DHCPv4, conformance test plans, ECUs, application layer, presentation layer, session layer (these reflect the primary protocols and scope addressed by the standard).
