Good point.

It seems that your draft is discussing two things:
1. TE reachability information exchange
2. Exchange of aggregated TE information for a domain

As you point out in section 4.2, the issue of scalability and policy needs
to be carefully considered before we pursue this too much further.

I think your work, especially the aggregation issues, meshes nicely with
the recent draft-ashwood-ccamp-gmpls-constraint-reqts-00.txt. Therefore, I
propose the following changes to the draft I sent out before...

1. Delete
   Jan 06 First version WG I-D Routing and signaling for complex optical
constraints
   Oct 07 Submit Routing and signaling for complex optical constraints I-D
for IESG review
2. Insert
   Jan 06 First version WG I-D Routing and signaling for link viability
constraints
   Oct 07 Submit Routing and signaling for link viability constraints I-D
for IESG review
3. Delete
    More forward-looking
    ====================
      Routing and signaling for complex constraints and inter-domain
        * first version of WG draft
          - based on draft-ashwood-ccamp-gmpls-constraint-reqts-00.txt
        * submit for IESG review
4. Add to Inter-domain section
    - Analysis and protocol changes for routing and signaling for link
viability constraints
      * first version of WG draft
        - based on draft-ashwood-ccamp-gmpls-constraint-reqts-00.txt
        - material from draft-otani-ccamp-interas-gmpls-te-03.txt
      * submit for IESG review

Cheers,
Adrian
