  1. Stateful PCE - update draft-ietf-pce-stateful-pce-07 draft-crabbe-pce-pce-initated-lsp-03 Ina Minei Ed Crabbe Jan Medved Robert Varga Siva Sivabalan

  2. Common updates to both drafts • Removed references to the LSP signaling type – aligning with the new version of draft-sivabalan-pce-lsp-setup-type-01.

  3. Base draft – draft-ietf-pce-stateful-pce-07

  4. Base draft updates • Address comments received during the last IETF • Very productive meetings in Berlin • Two revisions were produced (06 and 07) • Document slim-down from 59 to 46 pages • Focus on the base functionality • Stable document, ready for last review

  5. Base draft – what was removed? • Use cases – draft-ietf-pce-stateful-pce-app is now the only source of use cases • Optional state sync optimizations (and associated TLV) and triggered optimization moved to draft-minei-pce-stateful-sync-optimizations • Removed PCRep/PCReq extensions – lack of strong use cases. • Delegation parameters – lack of use

  6. Base draft updates – error handling • Spell out the encoding of the PCErr message • Clean up error handling for synchronization failures • Spell out error handling for the case of reaching the limits of resource consumption • Check error handling throughout the document

  7. Base draft - updates • Make the SRP object optional (and its absence equivalent to an SRP-ID-number of 0) • Based on feedback from the working group • Clarify • State compression • Use of the RRO • Add the egress node identifier to the LSP identifiers TLV

  8. Base draft - next steps • The document is stable • Implementation status • At least two vendors working on implementations, early versions available in shipping code from at least two vendors. • Request the working group for a thorough review, in preparation for last call.

  9. PCE-initiated LSP draft – draft-crabbe-pce-pce-initiated-lsp-03

  10. PCE-initiated LSP draft updates • Added the C flag to tag LSPs that were instantiated by the PCE • Clarified error reporting throughout • Updated the security section • Updated RBNF for LSP deletion to only send the SRP and LSP objects. • Added an implementation report section

  11. Next steps • Implementation survey showed several implementations already exist • Severaldrafts depend on this draft • The draft is stable • Ask the chairs to poll for working group adoption

  12. Stateful PCE synchronization draft-minei-pce-stateful-sync-optimizations-00 Ina Minei Ed Crabbe Jan Medved Robert Varga Xian Zhang Dhruv Dhody

  13. What is this? • Merged all the synchronization optimizations into one document • draft-zhx-pce-stateful-lsp-sync-00 • Synchronization optimization procedures from draft-ietf-pce-stateful-pce • No new content • Just clarification of the procedures

  14. Topics covered • State synchronization avoidance • PCE-triggered state synchronization • Incremental state synchronization

  15. Next steps • The content of this document was discussed in the past • Thoughts on how to progress?
