Project Example – Avionics Robust Ethernet Switch


A key player in the market of delivering complex and diverse engineering solutions for defence, security and aerospace customers in over
100 countries.

Customer Objectives

  • Software integration of an Ethernet switch in the next-generation avionics system.
  • Limited use case available, no clear feature content.
  • The solution must work on frozen hardware design and the existing Board Support Package (BSP).
  • Aerospace-grade solution: robust and no opportunity for upgrades or extension of features.
  • Reporting and monitoring are required.
  • Time-restricted delivery schedule.

AimValley Solution

The complete design makes use of the AimValley Portable Network Software Stack – AimOS.

AimOS-Ethernet-based solution internal CPU.
AimOS-E drivers ported to existing hardware and BSP.
Late hardware receipt, therefore, use of Broadcom reference design boards.
Introduced RoboOS improvements to AimOS-Robo; improving robustness required for Aerospace-grade solution. Integration and testing on customer hardware.

Results and Added Value


At least 20% faster time-to-market, thanks to AimValley having developed the building blocks of AimOS. 20% Cost reduction based on hours of development saved.


AimValley was able to help the customer to recover from the failed attempt by a previous design house.


Development in close collaboration up to integration of product.


Adapted standard solution to meet aerospace-grade requirements. Adding monitoring functions to the smart managed software.
