Hi,

I have a real concern with this draft because it appears to be heading us down the road of re-inventing PCEP in RSVP signaling with the dubious justification that it is needed in those situations in which a PCE is not available.  However, if you re-invent PCEP in RSVP signaling, then you have effectively ensured that there are no situations in which a PCE or its signaling equivalent are not available.

Why is this better than simply ensuring that a PCE is available in those situations in which it is needed?

Yours Irrespectively,

John
