Hi Tomohiro,

Thanks for reading the draft.

The intention is that the inter-as and inter-area drafts are inputs to this ID. The
framework should not contradict any requirements expressed in those drafts.

It was certainly not the intention to limit the scope to MPLS.
There will certainly be some techniques that are described that are only applicable to
MPLS. It will be the job of an applicability statement for a specific proposed solution to
show what functions and scenarios are supported.

It is absolutely not assumed. It is described as only one of the possibilities.
We would welcome text from you if you feel we have missed out any other possibilities.

Any suggestions?

The intention is to list the possible techniques that solutions may pick from.
Solutions still have to
- show that they meet requirements
- state their applicability
- define any usage or protocol extensions.

Kireeti may care to comment as the independent co-chair in this case.
My reading is that we are chartered to derive solutions for both environments and that it
would be good to have solutions that are applicable in both situations.

Perhaps you could develop this discussion by suggesting what you would like to see
included in / ommitted from a GMPLS draft.

Thanks.
Adrian
