Applicability of GMPLS for beyond 100 Gbit/s Optical Transport Network
draft-ietf-ccamp-gmpls-otn-b100g-applicability-15

(revised ballot to correctly acknowledge the SECDIR reviewer; thanks to Rob Wilton for pointing it out)

Thank you to David Mandelberg for the SECDIR review.

** Section 8.  As the premise of this document appears be around applicability to [ITU-T_G709_2020], it seems that relationship should be explicitly described in the Security Considerations.  Consider:

OLD
This document analyses and reuses the protocol extensions in
   [RFC7138] and [RFC7139] without introducing any new extensions.
   Therefore, this document introduces no new security considerations to
   the existing signalling protocol and routing protocol comparing to
   [RFC7138] and [RFC7139].  

NEW
This document analyzed the applicability of protocol extensions in [RFC7138] and [RFC7139] for use in the 2020 version of G.709 [ITU-T_G709_2020] and found that no new extensions are needed.  Therefore, this document introduced no new security considerations to the existing signaling and routing protocols beyond those already described in [RFC7138] and [RFC7139].

As I am not an expert on GMPLS at all, I can only have high-level comments.

The draft explains in length in section 3 how OTN next generation could work. The only part that is relevant to the IETF appears to be the 1-page section 4.2 (which basically writes "all is good for now"). While I am unsure about the added value of this document (again I am *not* an expert on this topic by far), if the CCAMP WG wants to publish this document and as I trust the AD and doc shepherd, then it is of course fine.

Before publication, please fix the authors' section as it has an unusual format.

Thanks to Joe Clarke for the OPSDIR review.
