TCP/IP stack for high-integrity systems

Over the last few months AdaCore has been working on developing a TCP/IP stack suitable for use in high-integrity systems. Technical details are provided below. For more information on commercial support please contact info@adacore.com.

FEATURES

AdaCore TCP/IP stack:

  • Targeted to bare-board embedded applications in certifiable systems.
  • Implemented in SPARK (information flow annotations included).
  • No Ada runtime requirement (supported on the zero footprint proile).

API:

  • Event driven architecture (based on LWIP design)
  • Application interface based on callbacks

Supported protocols:

  • IPv4
  • ARP
  • UDP
  • TCP
  • ICMP

Environment:

  • No requirement for an underlying OS
  • No threads used
  • For threading applications, user must ensure mutual exclusion
  • Support for multiple user supplied link level drivers (examples in C included: Linux socket/TAP interface, NE2k)
