Meral, PCE group is formed recently. If this is out of charter scope, it may be added on if this is really valuable function. As Adrian mentions that the basic architecture scope already 'adapt' this functionality, but seems it is clear how PCE performs this function yet. We are researching some advanced intelligent network to accomplish intelligent automatic LSP establish and tear down. If the reservation functionality is scoped out because of network size, I don't think that is proper. See more below.

I think Lucy has a point. But I do not think the draft needs to me modified. My comment on "the applicability of the PCE architecture in the Internet at large" comes from the following lines in the Description of Working Group. (http://www.ietf.org/html.charters/pce-charter.html). I was referring to: "The PCE WG will work on application of this model within a single domain or within a small group of domains (where a domain is a layer, IGP area or Autonomous System with limited visibility from the head-end LSR). At this time, applying this model to large groups of domains such as the Internet is not thought to be possible, and the PCE WG will not spend energy on that topic." This said, I think if our ultimate goal is to do inter-AS TE and path optimization in a PCE-based architecture, we must consider TED updating issues and PCE signaling responsiveness while we are still at the definition stage of the architecture and signaling protocols. Lucy: I don't see the conflict here. WG should study all these issues. However, these should not prevent from studying time-based reservation either, especially in the architecture design stage.
