[Pce] Quick Review of SR Inter-domain and association

[Dhruv Dhody <[e-mail]>]

Hi Authors,

I did a quick review of the I-Ds, but some key questions came up, it
would be nice if they could be clarified before hand.

--

(1) Association:

It is important to describe where this association exist and what role
does that play, to me the importance of the association is at the
Parent PCE only and thus the existing Stateful H-PCE [1] procedures
should be enough IMHO.

See figure 2 in your I-D, ASSOC 1 LSPs are distributed between all the
other child PCEs and thus not at clear why a child PCE need to be
aware of the association when it does not know any other LSP (outside
of its domain, that are part of the same association group).

--

(2) Path Segment:

I saw the spring I-D [2] as well, and was thrown by the use of path
segment as a way to stitch. My gut feeling was isn't that more like a
binding segment? Also for stitching label in PCE, please check
Olivier's I-D [3].

So, some clarity on what exactly you would like to achieve and the
reason behind the use of association and path segment is required.

I hope you would focus on these aspects during your presentation.
Discussion on the list would be even better.

Thanks,
Dhruv
