Safety-critical aerospace and defence networks

Deterministic Ethernet for safety-critical Aerospace & Defence Systems​​

 

Aerospace and defence applications place the highest demands on communication networks. Deterministic behavior, fault tolerance, and predictable performance must be guaranteed at all times, even under the most challenging operating conditions. From flight control and avionics networks to mission-critical systems and onboard communications in spacecraft, Ethernet is increasingly becoming the foundational networking technology. Modern Ethernet standards now enable compliance with the stringent requirements of safety-critical aerospace and defence certifications.​

TSN Systems solutions support the validation of Ethernet-based networks with a particular focus on emerging technologies and standards such as Time-Sensitive Networking (TSN). In addition, they enable the analysis and verification of the interaction between modern Ethernet networks and traditional bus systems.
Our products provide the measurement and validation capabilities required to ensure standards compliance, interoperability, and system-level conformance across all connected devices. They support adherence to relevant standards and profiles such as GVA, NGVA and IEEE 802.1DP, while ensuring reliable operation even in highly complex, redundant network architectures—with sub-microsecond timing accuracy.

Whether for aviation, space, or defence applications, TSN Systems delivers the tools and validation expertise needed to design, verify, and operate deterministic networks with confidence—providing the transparency, control, and assurance required for mission-critical environments.

Challenges

 

Aerospace & Defence Networking – Determinism and Reliability by Design

 

• Support for mixed-criticality networks, where flight-critical, mission-critical, and non-critical data traffic coexist on a consolidated communication infrastructure.

• Validation of deterministic and time-sensitive network behavior under real-world operating conditions and traffic loads.

• Verification of key certification parameters, including timing performance, end-to-end latency, jitter, and synchronization accuracy.

• Early validation of network architectures during the system design and architecture phase, before costly integration activities begin.

• Testing of real networks and device interactions rather than relying solely on theoretical or idealized simulation models.
