Julien -

Reading the CCAMP notes (which capture little of the actual discussion) I see that there may have been a perception in the room that PCE functionality at the UNI-N was assumed (actual or proxy).

This is not the case.  The reason for our draft is that with the UNI, much of the functionality that resides at the headend is moved to the UNI-N.  So the UNI-C needs a way to express an objective function even if there is no PCE.

Operationally it seems burdensome to require a PCEP at the UNI-C and a PCEP at the UNI-N, when all that is being done is enabling the UNI-N to perform what the client would do if it were connected to the network via a normal link.

Do you still object to the draft?

Thanks,

…George
