Hi, Dear PCErs, 

   We have updated the stateful PCE applicability draft and it is available at http://www.ietf.org/internet-drafts/draft-zhang-pce-stateful-pce-app-01.txt. 
  
   The major updates, besides some editorial work,  include:
  (1) confine the scope this document and refer to stateful PCEP extension related drafts; 
  (2) add "use of the information of under-construction LSPs" subsection and relevant explanations; 
  (3) add contents for manageability and security considerations; 

  Comments and suggestions are welcome. 

Regards,

The authors

Abstract:
   The Path Computation Element (PCE) provides a solution for Traffic
   Engineering (TE) based path calculation in large, multi-domain,
   multi-region, or multi-layer networks. Depending on whether a PCE
   keeps information about LSPs and reserved resource usage in the
   network or not, it can be categorized as either stateful or
   stateless.

   This memo describes general considerations for stateful PCE(s) and
   examines its applicability through a number of typical scenarios. It
   shows how stateful PCE(s) can be applied to facilitate these
   applications. PCEP extensions required for stateful PCE usage are
   covered in separate document(s).
