Road vehicles -- In-vehicle Ethernet

This document provides supplemental specifications to a physical layer capable of transmitting 1 Gbit/s over plastic optical fibre compliant with ISO/IEC/IEEE 8802-3:2017/Amd 9:2018, with specific application to communications inside road vehicles. Additionally, there is a test plan specified for conformance testing. The test plan includes test cases to assure compliance of an IUT with the functionality specified in this document. ISO/IEC/IEEE 8802-3:2017/Amd 9:2018 is considered indispensable for the application of this document. The supplemental specifications include wake-up and synchronised link sleep functionality. The specification includes the sublayers, service interfaces, and state diagrams that support the functionality. The supplemental specifications are collected in protocol implementation conformance statement (PICS). The requirements specified in ISO/IEC/IEEE 8802-3:2017/Amd 9:2018 and in this document constitute the complete PICS that specifies the GEPOF physical entity functionality. The optical component requirements and test methods for optical 1-Gbit/s transmission of in-vehicle Ethernet are not within the scope of this document.

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

ISO 21111-3:2020(E)
Introduction

The ISO 21111 series includes in-vehicle Ethernet requirements and test plans that are disseminated in

other International Standards and complements them with additional test methods and requirements.

The resulting requirement and test plans are structured in different documents following the Open

Systems Interconnection (OSI) reference model and grouping the documents that depend on the

physical media and bit rate used.

In general, the Ethernet requirements are specified in ISO/IEC/IEEE 8802-3. The ISO 21111 series

provides supplemental specifications (e.g. wake-up, I/O functionality), which are required for in-vehicle

Ethernet applications. In road vehicles, Ethernet networks are used for different purposes requiring

different bit-rates. Currently, the ISO 21111 series specifies the 1-Gbit/s optical and 100-Mbit/s

electrical physical layer.

The ISO 21111 series contains requirement specifications and test methods related to the in-vehicle

Ethernet. This includes requirement specifications for physical layer entity (e.g. connectors, physical

layer implementations) providers, device (e.g. electronic control units, gateway units) suppliers, and

system (e.g. network systems) designers. Additionally, there are test methods specified for conformance

testing and for interoperability testing.

Safety (electrical safety, protection, fire, etc.) and electromagnetic compatibility (EMC) requirements

are out of the scope of the ISO 21111 series.

The structure of the specifications given in the ISO 21111 series complies with the Open Systems

[1] [5]

Interconnection (OSI) reference model specified in ISO/IEC 7498-1 and ISO/IEC 10731 .

ISO 21111-1 defines the terms which are used in this series of standards and provides an overview of

the standards for in-vehicle Ethernet including the

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

ISO/FDIS 21111-3:2020(E)
Introduction

The ISO 21111 series includes in-vehicle Ethernet requirements and test plans that are disseminated in

other International Standards and complements them with additional test methods and requirements.

The resulting requirement and test plans are structured in different documents following the Open

Systems Interconnection (OSI) reference model and grouping the documents that depend on the

physical media and bit rate used.

In general, the Ethernet requirements are specified in ISO/IEC/IEEE 8802-3. The ISO 21111 series

provides supplemental specifications (e.g. wake-up, I/O functionality), which are required for in-vehicle

Ethernet applications. In road vehicles, Ethernet networks are used for different purposes requiring

different bit-rates. Currently, the ISO 21111 series specifies the 1-Gbit/s optical and 100-Mbit/s

electrical physical layer.

The ISO 21111 series contains requirement specifications and test methods related to the in-vehicle

Ethernet. This includes requirement specifications for physical layer entity (e.g. connectors, physical

layer implementations) providers, device (e.g. electronic control units, gateway units) suppliers, and

system (e.g. n
