10


Audio/Visual

▪ Multimedia synchronization requirements

▪ Avnu Alliance, giving more than

10 years of Ethernet AV experience

▪ ProAudio (e.g., 1722) + AVB/TSN functionality

Applicable Audio/Visual Capabilities


11


Industrial Automation

▪ History of safety designs and

communication on single network

▪ Migration to Ethernet over past 17 years

▪ Merging to common platform using TSN

features

▪ IIoT: Industrial application of IoT

▪ Security infrastructure supporting low-

cost devices

▪ Past separation of OT and IT networks

Industrial Automation’s Contribution


12


Automotive

Learning from Traditional Automotive Networking

▪ Deterministic networks

▪ Advanced safety designs

▪ Validation/Testing

▪ Cost and configuration sensitivity

▪ Reliability


13


Both industrial and automotive

networks need to be concerned about

• Safety

• Traffic determent/time synchronization

awareness

• Security

What is different is the scale: a large-scale plant compared to a car

• Small resourced constrained devices

Industrial vs. Automotive Networks

Industrial and Automotive TSN Profiles

TSN Profile for Industrial Automation

TSN Profile for Automotive

TSN Profiles for Both

▪ Translation of terminology to

IEEE TSN Standards

▪ Based on use case

requirements

▪ Network deterministic

IEC/IEEE 60802Scope: Defines time-sensitive networking

profiles for industrial automation.

IEC/IEEE 802.1DGScope: Defines time-sensitive networking

profiles for Automotive.

All of the above + time

How Does TSN Functionality Support In-Vehicle Networks?


17


Putting It Together

▪ Zonal Approach

— Add gateways to connect

sensor data

▪ Enterprise switch technology

— High-speed backbone to

support 10G and beyond

— Upcoming 802.3ch standards

▪ Common Ethernet technologies

— Solution source for specific use

cases

Taking Advantage of Other Industries’ Capabilities


18


Future Considerations Enabled by the Ethernet

▪ Disturbed control and load sharing

— Zonal architecture

moving away from

traditional domain-

control architecture

▪ Fail operational

— Seamless

communication

between zonal nodes

opens up possibilities


19


How Does the Ethernet Help?

▪ Common infrastructure

▪ Layered approach

— Virtualized networks

— Physical separation

▪ Scalability

— 10 Mb to 10 Gpbs and beyond

▪ Vast experience to leverage

— Industrial automation: Time-sensitive,

safety-critical environments

— Enterprise/AV: High-speed

communications, high reliability

▪ Opens possibilities we haven’t

even though of yet
