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 Cases & Requirements document.

The consolidated Use Cases & Requirements document can be found in the Contributions section, below. Look for the title “P802.1DG Automotive Use Cases & Requirements”, or see filenames beginning with “dg-pannell-automotive-use-cases-” in the 2019 and 2020 public directory for a complete list).

Teleconference Information

Information about the bi-weekly calls can be found on the TSN Calls page. Announcements for the calls, and associated updates, are sent to the Main 802.1 List (STDS-802-1-L); for instructions on subscribing go here: https://1.ieee802.org/email-lists/.

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

Attendance is done via IMAT during the scheduled time for the call. You will need a free IEEE account to use IMAT.

Joining the Task Group and Voting

Anyone can join the teleconference calls and view the public Contributions. However, if you want to view the drafts and participate in the balloting process you will need to join the Main 802.1 List (STDS-802-1-L). After joining you will be sent an introductory email explaining how to access the drafts and email archives.

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

Please contact the Editor if you have comments to this TSN P802.1DG page.
