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.

Filename: draft-zhang-pce-stateful-pce-app Revision: 01 Title: Applicability of Stateful Path Computation Element (PCE) Creation date: 2012-07-13 WG ID: Individual Submission Number of pages: 23 URL: http://www.ietf.org/internet-drafts/draft-zhang-pce-stateful-pce-app-01.txt Status: http://datatracker.ietf.org/doc/draft-zhang-pce-stateful-pce-app Htmlized: http://tools.ietf.org/html/draft-zhang-pce-stateful-pce-app-01 Diff: http://tools.ietf.org/rfcdiff?url2=draft-zhang-pce-stateful-pce-app-01 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).
