An interesting idea.
If my understanding is not wrong, the
draft describes the architecture and PCEP extensions that the NSBP (PCC)
sends out the route offer computation request to Service-PCE.
the NMS (PCC) sends out the PCReq messages to PCE is described in RFC4655,
What the procedure looks like if NMS is also involved? or NMS will not
appear when the route offer computation is adopted?
Sorry that I am not familar with the
TMF IPSPHERE Framework, hope

we've just posted a new I-D about extending PCEP with a new route
information, the price.
As explained in the I-D, the route price is an additional info with
respect to the route cost(s) currently well covered by existing PCE RFCs
And this extension seems to us quite useful in those scenarios where a
Service Plane interfaces to PCE for elaborating its route offers.
Your feedbacks and comments would be very much appreciated.
