Dear Authors, et. al,
please find my comments and questions to the latest version below. Thank you
for your kind consideration.
* Would you agree that use case document is more appropriate on
Informational rather than Standard track
* Introduction, second para
o Precomputation and instantiation of protection/backup paths is
characteristic of all protection mechanisms, local, segment and end-to-end.
o "The term "protection" is often used as a synonym for FRR." I think that it
is "local protection" that is being equated and used interchangeably with FRR.
End-to-end protection, whether linear or ring, equally supports 10msec fault
detection as fault detection latency is not characteristic of protection
mechanism but of interval used in continuity check OAM.
* Section 3
o first sentence s/in/of/
o Does local protection in SPRING network domain takes into consideration SID
labels. If SID labels are not being considered when pre-calculating backup
tunnels then it is possible that after the switchover end-to-end path fails. On
the other hand, if SID labels being considered, then, in general case,
intermediate node must maintain path information, which is not as Segment
Routing paradigm being defined at this time.

Greg
