Re: [Detnet] Transport sub-layer name change (Was Re: Tsvart last call review of draft-ietf-detnet-architecture-08)

["Andrew G. Malis" <[e-mail]>]

This terminology is certainly appropriate for TEAS. For DetNet, this seems
to make the assertion that the DetNet underlay is always
traffic-engineered, even if IPv4 or IPv6 (which is certainly possible using
TE extensions for the IGPs).

As long as people are OK with this assertion, then I'm OK with it as well.
That should be made clear in the architecture spec where the term "DetNet
TE sub-layer" is introduced/defined.

Cheers,
Andy
