ELISA Annual Virtual WG Updates

Railways Working Group Discussion

  • Deutsche Bahn & SNCF cannot join today.
  • No response from Scheidt-Bachmann yet.
  • Henrik from RWTH Aachen joined today also interested in the group.
  • Idea is to have initial discussions out of TSC row. Meeting poll will come.
    • Draft for the Railways WG is created for discussion in such a meeting.
    • Philipp will send the poll for a separate call.
  • TSC New WG proposal template can be found here https://github.com/elisa-tech/tsc/blob/master/new-wg-template.md
  • Bring this to the agenda on next TSC again.
  • Railway is interesting for ELISA as this belongs to the safety regulated industries.
  • There is also information on usage of Linux in trains ;-)
  • SIL2 use cases are on the way for automated trains.
  • Railway has safety layer with certain components (e.g. communication) supporting the safety application without being the safety application. Where are these middleware layers located.
    • This is not limited to Railways, but also fit to other industries (like Automotive)
  • Derived discussions (not Railway specific):
    • Two approaches: Safety requirements allocated to Linux and Linux without safety responsibility, but being used in safety applications (as "QM / SIL0")
    • "Linux in safety applications" also does not clearly define what it includes. If it is only the kernel or the Linux systems.
    • Could be implemented in a cross functional (industries) working group defining the requirements towards Linux
      • Linux Features looks into a minimal application cross industries.
      • Linux should behave as expected by its implementation (e.g. by its documentation)
      • Systems WG addresses an ASIL decomposition and systems where Linux may be QM
      • Watchdog is also common to most architectures and industries.
      • Maybe it is enough to make this more clearly and defining a framework that the verticals can frame main features and map them to Linux. This need to be more formalized to be aligned.
    • Point was made that the same OS can be sold to different industries. Though the way to express expectations of the industries are not identical
    • AI: Need to follow up on this. Systems or Arch WG meeting is a good place for this.

Next ELISA WS thoughts and considerations

  • Tentative May 20-22 somewhere in Europe
    • Like in past: First 1/2 day in the afternoon + 2nd full day + 3rd 1/2 day in the morning (for better traveling)
    • Tuesday to Thursday is nice for people joining from US (No travel on Weekend)
  • Being more intentional to include more time for discussions
  • Closer to unconference sessions (e.g. 10 minute topic introduction, 30 min discussion, 10 min wrapup and next steps)
  • Min will prepare a poll to check availability for May 20-22 and May 7-9 being okay or not.
