variation patterns
or mechanisms as preferred by some

6. Product Architecture Derivation

and configuration management systems

7. compilation

8. linking
including libraries

9. run-time
adaptation during startup and adaptation during normal execution

10. After market services
3rd party integration
Software re-use

11. run-time
we argue that
variability
BUT
is the shit

12. it is HARD

support for variability .

16. HOW
DID WE
DO IT?

17. 1
PHASE
Subscriber

Light weight implementation in

Towards automotive industry standard

20. HOW
DID WE
DO IT?

21. It is possible
to have run-time in AUTOSAR and remain compliant

22. Our publisher
subscriber is better
then all the others...
Publisher
Subscriber

23. Manage subscriptions
Real-time challenges
Low coupling

24. Variation point
Hi, my name is
PubSub, may I
join you?

25. 400 000

26. RE.CAP

27. it is hard

28. we made a prototype

29. based on a problem from VOLVO

30. using AUTOSAR

31. it is possible!

32. publisher subscriber pattern

33. real-time constraints

34. subscription management

35. WHAT?
SO
WHY DO WE CARE ABOUT THIS?
