The transition toward digital vehicle architectures in military ground defense, naval platforms, and avionics requires hardware capable of handling localized data aggregation. Kontron has introduced the CERES-TSN, a managed Layer 2/3 Ethernet switch designed for embedded tactical networks. The unit integrates a Microchip LAN9696TSN switch fabric to support complex network architectures. It provides up to 28 fully managed ports, configured as 24 Gigabit Ethernet ports and four 10-Gigabit Ethernet optical interfaces, utilizing MIL-DTL-38999 circular connectors. This configuration yields a line-rate forwarding performance of up to 66 Gbps, ensuring sufficient bandwidth for concurrent data streams.
Deterministic Communication and Synchronization
For systems relying on sensor fusion, high-resolution camera streams, and rapid threat detection, predictable data delivery is a technical requirement. The switch hardware incorporates time-sensitive networking (TSN) capabilities, specifically supporting the IEEE 1588v2 Precision Time Protocol and IEEE 802.1AS standards. These protocols provide microsecond-level clock synchronization across the network, facilitating low-latency, deterministic communication across combat vehicle networks, C4I/C4ISR systems, and tactical data acquisition platforms.
Management Protocols and Device Security
Network routing is managed through IPv4 and IPv6 protocols, supported by multicast capabilities, Quality of Service (QoS) prioritization, and Virtual Local Area Network (VLAN) segmentation. Administrators can configure the hardware via Simple Network Management Protocol (Snmp), a Command Line Interface (CLI), or a web-based graphical user interface. Network access is governed by IEEE 802.1X authentication, alongside Secure Shell (SSH) and HTTPS encryption. A secure boot sequence is available upon request to verify firmware integrity during startup. Additionally, optional Power over Ethernet Plus (PoE+) provides a direct power supply to connected edge devices, mitigating the need for independent power lines and reducing overall cabling weight.
Environmental Specifications and Export Compliance
The fanless, conduction-cooled enclosure is rated to IP65, providing protection against dust and water ingress. The hardware operates in extreme thermal conditions ranging from -40°C to +55°C, with extensions up to +71°C available. It complies with MIL-STD-810G for mechanical shock and vibration, as well as MIL-STD-461F for electromagnetic interference. Designed and manufactured entirely within Europe by a single supplier, the platform is free from International Traffic in Arms Regulations (ITAR) and Federal Office for Economic Affairs and Export Control (BAFA) restrictions. This regulatory status streamlines procurement and safety-critical qualification processes by removing dependencies on third-party modules.
Implementation and Availability
"The hardware brings together deterministic networking, high forwarding performance, and network security protocols in a conduction-cooled design, supporting the integration of reliable network infrastructures," stated Sébastien Vitre, Product Manager, Rugged Systems at Kontron. A 28-port version is currently available, with a second variant scheduled for release later in the year. Kontron exhibits the hardware at the Eurosatory trade show in Paris from June 15 to 19, 2026, in Hall A, Booth E55.

The integration of time-sensitive networking into ruggedized military hardware aligns with the broader industry shift toward Ethernet-based vehicle and avionics architectures. Competitive solutions in the defense sector, such as those utilizing Cisco ESS3300 embedded switch modules or comparable Curtiss-Wright Parvus systems, typically offer between 10 and 24 ports of Gigabit Ethernet combined with separate 10-Gigabit optical uplinks. The implementation of the Microchip LAN9696TSN fabric allows the Kontron unit to achieve a 66 Gbps forwarding capacity, which meets baseline engineering requirements for high-definition video distribution and real-time radar data processing at the tactical edge. Furthermore, relying on an ITAR-free European supply chain distinguishes the hardware in procurement scenarios where strict export control regulations limit the deployment of North American silicon and network components.
