What is TSN?

TSN is a real-time Ethernet solution using an open standard, and encompasses:

• Hardware in the loop extensions to standard Ethernet, with real-time synchronization
• Prioritization with traffic scheduling
• Determinism & bounded latency communication
• High availability
• Robustness
• Reliability

What could TSN do for your future vehicle?

Sensor Fusion

• Due to the ability to control hardware time synchronization, TSN eliminates clock drift between systems allowing for real-time fusion
• A redundancy and deterministic network allows for shared sensors across the platform, reducing weight and duplications
• Increases the quality of data a system receives
• Improves system reliability
• Reduces latency and provides determined latency in the system

Vehicle Prognostics

• True prognostics can best be achieved with both sensor and system-level fusion. TSN provides the common backbone with the bandwidth required. 

Increase bandwidth

• Allows for much greater versatility and higher data throughput so that devices can communicate in real time
• Substantially increases the responsiveness in systems
• Centralized shared systems reduce SWaP (Size, Weight, and Power)

Cyber Threats

• Build in cyber resiliency by using Filtering and Policing of incoming frames (PSFP) and path control and reservation (PCR)
• A switch-based network instead of point-to-point allows for duplicating frames to be sent on multiple paths
• Stream Reservation Protocol allows the system to identify an attentive path with the same latency
