Time-Sensitive Networking (TSN)


What would your system be like with a 40 gigabit deterministic network?

The future of deterministic aerospace networking...TSN!

Time-Sensitive Networking (TSN) provides highly reliable, time synchronization and deterministic delivery of mixed media (i.e., control data, video, audio, etc.) to fulfill the requirements of both safety critical applications and real-time communication systems.

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


Why do you need TSN?

  • TSN is used for time-sensitive transmission of data over deterministic Ethernet and has 1000 times the bandwidth over the current 1Mbit 1553 data rate
  • IEEE 802.1 Standard meets the need for an open Standards for Communication that is not driven or owned by one large company
  • ONE network for everything, with the best effort and critical data over one network
  • Easy migration path from existing networks and Interoperability are critical drivers for TSN


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


Do you need to guarantee that your Ethernet frames get there on time, every time? 

Well, look no further. DDC offers a suite of TSN Ethernet products that guarantees data delivery. Whether you need a TSN Endpoint or a TSN Switch, DDC has a solution for you, from chips to boards to systems.
