Hi all,

There are no major changes in this new version.
As required in Dallas, authors of this draft and authors of the policy framework draft discussed together to see whether the inter-area path computation application had an impact on the policy framework and whether there were additional policy requirements for the PCECP. It resulted that no new element needs to be added in this requirement draft. But we reformulated the policy section (section 5.7) to clarify the requirements.

We are waiting for your comments on this new version.

Best Regards,

JL
