Minutes
PCEP MIBs
- Discovery, Core and P2MP MIBs will require an early MIB Dr Review, can be done prior to Last Call.
2. PCEP Extensions to Compute Service-Aware LSPs
- Co-chair outlines that working group will not Last Call until IGP work has progressed.
3.1. Stateful PCE Applicability
- Co-chair request to please comment and discuss the document.
3.2. PCEP Extensions for Stateful PCE and PCE-Initiated LSPs
- Authors do not see significant changes and suggest the document is “stable”.
- Observation that the document has been reduced in size.
- A number of comments made regarding single or sets of documents related to PCE-Initiated LSP setup. Area Director (Adrian Farrel) provided some advice and a poll was conducted. The sense of the room was against merging MPLS and GMPLS documents, very few being opposed to 2 sets.
draft-crabbe-pce-pce-initiated-lsp-03
- Reminder to address questions on the mailing list.
- Co-chairs conducted an Adoption Poll, good support and the question will be taken to the list.
draft-minei-pce-stateful-sync-optimizations-00
- A request for participants to review and comment on the working group list.
3.3. PCEP
Extensions for Stateful PCE and GMPLS LSPs
- No questions.
3.4.a. PCEP Extensions for Remote-initiated GMPLS LSPs
- A number of questions related to congestion, bandwidth availability, and co-ordination between layers. The response was a suggestion to move the discussion to the CCAMP working group.
-
Questions remain if use cases for remote-initiated mechanism should
appear in PCE Stateful Applicability I-D.
- Co-chair requested that the document scope needs to be clarified before progressing the document.
3.4.b. PCEP Extensions for Remote-initiated GMPLS LSPs
- Again, co-chair requested that the document needs further discussion and clarification.
3.5. Conveying Path Setup Types in PCEP
- Document proposes a generic TLV for simultaneously support of more than one path setup type (in addition to RSVP-TE).
- Further documents will be required, to describe these other setup mechanisms.
- Discussion required to see if these Path Profiles will be well-defined, or Operator assigned?
- Co-chair requested further discussion on the list for the document.
3.7. Use Cases for PCE as Central Controller
- No questions.
3.8. Application-oriented Stateful PCE Architecture and Use Cases
- Questions to list as we are out of time.
- Currently out of charter, we need to complete recently chartered work (Stateful).
4.1. Secured Transport for PCEP
- Some support in the room for the work. A request not to provide too many options, which may over complicate the proposal.
- Request from the co-chair to circulate work with DNS experts within the IETF, and other relevant working groups.
- No time for further questions.
4.3. PCEP Extensions for Receiving SRLG Information
- Disagreement from some participants in the room who felt that policy discussion within CCAMP needs to be reflected.
- Suggestion to move the discussion to both the PCE and CCAMP list.
5.1. TED Dissemination for Hierarchical PCE
- No time for questions.
End of Session 15:30
No time for additional presentations, a request from the co-chair to email the list and point to the slides.
