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

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.

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

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

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

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

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

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.

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

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

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

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

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

Topics covered State synchronization avoidance PCE-triggered state synchronization Incremental state synchronization

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