Hi Sander, This separation of architecture is not new; see https://datatracker.ietf.org/doc/draft-ietf-spring-nsh-sr/ in the SPRING WG.

Clear separation of concerns in a SPRING architecture! I was afraid the hope for a clear architecture was lost, but this makes me so happy :) Cheers, Sander And to be 100% clear: I'm not being sarcastic… The messy "architectures" I have seen in the past have driven me to despair. This work is finally something that makes sense. _______________________________________________ spring mailing list spring@ietf.org https://www.ietf.org/mailman/listinfo/spring
