[Detnet] Re: IETF 122 Slot Requests

[CARLOS JESUS BERNARDOS CANO <[e-mail]>]

Thanks Lou for the feedback.

I agree with your proposed way forward. I’ll start working on that
direction and present some ideas during the meeting. My idea would be to
start working on the definitions of a multi-domain detnet, and then start
working on the PCE-based detnet controller framework (there I don’t have
yet a clear idea on how to do it, one could be definitely the one you
propose).

Thanks,

Carlos
