Technology Demonstrators and Implementations

Babelya and Domynik are implementations and demonstrators of CetraC that show how CetraC technology can be used to design a multi-protocol switch or an end system. You can use these implementations, or build your own using the CetraC toolkit and resources.


Babelya is a multi-protocol switch designed on top of Cetrac technology.

  • 802.3 Ethernet protocol : 8 Ethernet ports at 10/100/1000 Mbps
  • IEEE 1588v2 protocol : PTP
    • System clock distribution : grand-master or client
    • Internal clock resolution at 5ns
  • ARINC664 Part7 up to 1 Gbps
  • Key element of an IMA2G compliant network
  • Protocol availability : UDP, TCP, ARP, ICMP
  • Supports Unicast, Multicast, Deterministic Broadcast
  • Dual link redundancy
  • Guaranteed Real Time and QoS
  • Filtering on IP, MAC, protocol
  • Network topology free through all or CetraC™ compatible devices
  • Security features, fault detection and reporting
  • Technology compliant with RTCA / DO-254 ED-80 CSPN certification by ANSSI (in prog’ess)


Domynik is an End-System, with features such as :

  • 100% Hardware protocol handling
    • Ethernet IEEE802.3
    • ARINC664p7
