Hi all, A new version of the PCE-based inter-layer framework draft has been published below.
Main changes are: - We modified sections 5 and 6 to clarify the communications between PCE and VNTM. - I added section 6.5 (Separation of Layer Management). - Other changes are to move the text around for clarity. Any comments and suggestions are highly appreciated. Thank you.
