Hi All, 

We received a number of comments from the PCE document shepherd and also
during WG Last Call for this I-D. The recently submitted (07) version of the
I-D addresses a number of those comments, including:

- Inclusion of use-cases and applicability of hierarchical stateful PCE
- Updated references 
- General nits

Our plan is to submit another update soon [1], which addresses the remaining
open issues.  

BR, Dan.

Abstract:
   A Stateful Path Computation Element (PCE) maintains information on
   the current network state, including: computed Label Switched Path
   (LSPs), reserved resources within the network, and pending path
   computation requests. This information may then be considered when
   computing new traffic engineered LSPs, and for associated
   and dependent LSPs, received from Path Computation Clients (PCCs).

   The Hierarchical Path Computation Element (H-PCE) architecture,
   provides an architecture to allow the optimum sequence of
   inter-connected domains to be selected, and network policy to be
   applied if applicable, via the use of a hierarchical relationship
   between PCEs.

   Combining the capabilities of Stateful PCE and the Hierarchical PCE
   would be advantageous. This document describes general considerations
   and use cases for the deployment of Stateful PCE(s) using the
   Hierarchical PCE architecture.
