Safety Becomes Omnipresent
Megatrend Safety
• Automotive: 50 million injuries, out of those 1.2 million were fatal injuries (3.300 per day according to WHO 2010)
• Industrial: Manufacturers lose over $ 20 billion each year in safety incidents (Norm Gilsdorf, President of Honeywell Process Solutions at Honeywell User Group 2010)
• Civil Aviation: In 2010 there were 47.3 million flight hours and 22.3 million departures with 9 serious accidents
• Smart and safe mega cities• Medical systems and healthcare for aging populations• By 2020 every second embedded device will be safety relevant

Encapsulated Data Streams for Safety and Availability
• TTEthernet controls data rates and arrival timing against pre-set allocation tables
• Policing of data rates is enforced by the switch
• Based on TDMA scheme with clock-synchronization
Safety Argument• Data streams of different functionality
are protected against each other and• Data streams of different criticality are
protected against each other • By encapsulation
