Hi, We have just published a new PCE draft concerning alternative ways of transporting TE data that may not depend on IGP-TE or BGP-LS.
The motivation for this work is a timely update of TE data directly from nodes to PCE(s) to support scenarios like: (i) networks that do not support IGP-TE or BGP-LS but want to implement PCE. (ii) applications that require accurate and timely TE data that current convergence time associated with flooding is not justified. (iii) reduction of node OH processing of flooding mechanisms (esp. optical transport networks where there are large amounts of traffic data and constraints due to OTN/WSON/Flexi-grid, etc. Note that also BGP-LS is not supported in optical transport networks today) Your comment will always be appreciated. Thanks, Young (on behalf of other co-authors) -----Original Message----- From: [email protected] [mailto:[email protected]] Sent: Wednesday, July 02, 2014 4:32 PM To: Greg Bernstein; Dhruv Dhody; Greg Bernstein; Zhenghaomian; Dhruv Dhody; Leeyoung; Leeyoung; Zhenghaomian Subject: New Version Notification for draft-lee-pce-transporting-te-data-00.txt A new version of I-D, draft-lee-pce-transporting-te-data-00.txt has been successfully submitted by Young Lee and posted to the IETF repository. Name: draft-lee-pce-transporting-te-data Revision: 00 Title: PCEP Extensions in Support of Transporting Traffic Engineering Data Document date: 2014-07-02 Group: Individual Submission Pages: 20 URL: http://www.ietf.org/internet-drafts/draft-lee-pce-transporting-te-data-00.txt Status: https://datatracker.ietf.org/doc/draft-lee-pce-transporting-te-data/ Htmlized: http://tools.ietf.org/html/draft-lee-pce-transporting-te-data-00 Abstract: In order to compute and provide optimal paths, Path Computation Elements (PCEs) require an accurate and timely Traffic Engineering Database (TED). Traditionally this TED has been obtained from a link state routing protocol supporting traffic engineering extensions. This document discusses possible alternatives to TED creation. This document gives architectural alternatives for these enhancements and their potential impacts on network nodes, routing protocols, and PCE. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
