Re: Inter-AS GMPLS [Was: Moving forward with the CCAMP charter]

[Tomohiro Otani <[e-mail]>]

Hi Adrian,

Thank you for your e-mail message clarifying my comments.
I agree with your proposed milestone.

One point is that as you mentioned, our draft covers;
1. TE reachability information exchange
2. Exchange of aggregated TE information for a domain
In addition to these, in our draft, I also assume that GMPLS
inter-domain routing is required to exchange reachability information.
The draft should be short enough to clarify whether we
rely on the same (existing) protocol mechanism as IP/MPLS.

Regards,

tomo
