[CCAMP] R: I-D Action: draft-fuxh-ccamp-boundary-explicit-control-ext-03.txt

Hi Xihua,

I read the draft and I found it , as the first time, very interesting but a little unclear in some points.
Chapter 2.2.1
You say that boundary node “could” not determine which kind of ODUk FA-LSP should be triggered but you do not put any brief explanation of that. I think for completeness some words should be usefull.

Chapter 3.2.1
Not clear the sentence about L bit : MUST be included vs. SHOULD be included . I suppose you mean SHOULD not be included , Correct ?

Chapter 3.2.3
In chapter 3.2 you mention the possibility by ERBO to signal : FA nodes end points, and FA/component link.
Is the signal type sub-object devoted to this second scope ? I f yes, why named it explicitly (e.g. FA signal type ) and not just signal type , that is a little misleading. I would avoid the terms sub-layers already discusse in the mailing list since there is a different terminology and meaning for that in ITU. Let’s say level multiplexing or something along this lines.

Chapter 3.2.5
Not clear the sentence related to ERO : “If it is necessary , it must also extract the server layer/sub-layer routing information form ERO based on a pair of node. “ Could you clarify .

Chapter 3.3.1 and others :
L bit field : again the is the sentence Must be excluded vs Should be avoided . I do not believe a good idead permit anyway to use one resource that I’m considering to be excluded . I mean: it implies in case the SHOULD usage an interworking problem, right ?

Thanks

Sergio

Hi All,

We updated this draft.
We added some new sections, suchs as the "requirement identification" and "boundary nodes determination mechanism".
Some content are related to OTN multi-layer scenarios.
If you review and have some comments, pls let us know.

A New Internet-Draft is available from the on-line Internet-Drafts directories.

                Title           : RSVP-TE Extension for MRN/MLN Application

  [RFC5212] defines a Multi-Region and Multi-Layer Networks (MRN/MLN).
  [RFC4206] introduces a region boundary determination algorithm and a
  Hierarchy LSP (H-LSP) creation method.  However, in some scenarios,
  there must be some additional information to facilitate hierarchy LSP
  creation.  This document extends RSVP-TE to meet this requirement.
