P802.1DG – TSN Profile for Automotive In-Vehicle Ethernet Communications

This standard specifies profiles for secure, highly reliable, deterministic latency, automotive in-vehicle bridged IEEE 802.3 Ethernet networks based on IEEE 802.1 Time-Sensitive Networking (TSN) standards and IEEE 802.1 Security standards.

This standard provides profiles for designers and implementers of deterministic IEEE 802.3 Ethernet networks that support the entire range of in-vehicle applications including those requiring security, high availability and reliability, maintainability, and bounded latency.

The automotive segment does not have a standards-based profile for IEEE 802.1 Time-Sensitive Networking (TSN) standards as usage can vary widely based on the networking scenarios. The lack of a profile makes the definition of the automotive manufacturer’s requirements and the implementation of those requirements by suppliers more difficult and costly. Thus there is a need for standardization of the selection and use of IEEE 802 standards and features in order to be able to deploy secure highly reliable converged networks.

Use cases provided by individual contributors (e.g. dg-potts-auto-network-accum-cong-use-case-0319-v01.pdf) will be consolidated into a rolled up Use Case document (see filenames beginning with “dg-use-cases-” in the 2018 and 2019 public directories for a complete list). For an example of the Use Case document used by the IEC/IEEE 60802 TSN Profile for Industrial Automation project see: http://www.ieee802.org/1/files/public/docs2018/60802-industrial-use-cases-0918-v13.pdf.

A Requirements document (see filenames beginning with “dg-requirements-” in the 2018 and 2019 public directories for a complete list) will draw profile requirements from the Use Case document. For an example of the Requirements document used by the IEC/IEEE 60802 TSN Profile for Industrial Automation project see: http://www.ieee802.org/1/files/public/docs2018/60802-industrial-requirements-1218-v12.pdf.

Teleconference Information

Information about the bi-weekly calls can be found on the TSN Calls page. To log in to the call immediately, go here: https://join.me/ieee802.1 (Meeting Code is ieee802.1).

Participation and patent slides are reviewed at the start of each call.

Notices

In addition to the regular  IEEE 802 interim and plenary meetings held every two months, a special one-day Interim has been scheduled on 23 September 2019 to be held at the GM facility in Warren, MI, USA (near Detroit). The purpose of this Interim is to progress the work on this project. The date and location were chosen to make it convenient for those attending the IEEE-SA Ethernet & IP @ Automotive Technology Day (E&IP@ATD 24-25 September 2019) to attend this Interim by arriving a day earlier.

There is no fee for this Interim; however, for security purposes you do need to notify the meeting coordinator that you are attending. Look at the 23 September 2019 meeting information on the Interim Meetings page for details.

Other Projects of Interest

There are projects in the IEEE 802.3 Working Group that may be of interest to this group. Here are some relevant links:

  • IEEE P802.3cg 10 Mb/s Single Pair Ethernet Task Force (formerly the 10 Mb/s Single Twisted Pair Ethernet Task Force). This project is focused on lowering costs by removing the need for switches and sharing the 10 Mb/s Ethernet medium between multiple devices.
  • IEEE P802.3ch Multi-Gig Automotive Ethernet PHY Task Force. Note the discussions on asymmetrical data rates on this project (e.g. 10G from camera for video (forward channel), 100 Mb/s to 1 Gb/s to camera for control (backward channel)).

The Automotive profile is one of five profiles created by the TSN group. The other profiles are:

  • IEEE Std 802.1BA-2011 IEEE Standard for Local and metropolitan area networks–Audio Video Bridging (AVB) Systems
  • IEEE Std 802.1CM-2018 IEEE Standard for Local and metropolitan area networks — Time-Sensitive Networking for Fronthaul
  • IEC/IEEE 60802 TSN Profile for Industrial Automation

  • IEEE P802.1DF TSN Profile for Service Provider Networks
