PCE Working Group Meeting - Thursday, November 17, 2011, 1:00 PM

1. Introduction

1.1. Administrivia, Agenda Bashing (chairs, 5 min) [5/120]

1.2. WG Status (chairs, 10 min) [15/120]

2. GMPLS and Optical Networks

2.1. PCEP Extensions for GMPLS (Cyril Margaria, 5 min) [20/120]

draft-ietf-pce-gmpls-pcep-extensions

- Co-chair reminded authors that Last Call is not possible until all issues fixed. Further suggestion, considering the RSVP-TE aspect, the authors may want to poll CCAMP.

2.2. PCEP Requirement for RWA (Oscar Gonzalez de Dios, 5 min) [25/120]

draft-ietf-pce-wson-routing-wavelength

- Co-chair suggested that ID should remain active (and not Last Called) while the solutions draft stabilizes.

2.3. PCEP Extensions for RWA (Cyril Margaria, 10 min) [35/120]

draft-lee-pce-wson-rwa-ext

- Authors added a new section on OF’s. They requested WG feedback.

- Co-chair stated that the document is within the WG scope and listed as a milestone. Co-chair suggested the authors should provide some additional text (specifically the empty sections).

2.4. PCEP Extensions for Flexi-Grid Optical Networks (Yongli Zhao, 5 min) [40/120]

draft-zhaoyl-pce-flexi-grid-pcep-ex

- The WG was reminded by ITU contributors that the flexi-grid data-plane effort in the ITU is fairly recent and still requires significant discussion. PCE relevant work is therefore slightly premature.

- Authors were reminded of existing Global Concurrent Optimization (GCO) techniques are available (RFC5557).

3. Multi-Domain

3.1. Procedure to Compute P2MP Inter-Domain TE-LSPs (Daniel King, 5 min) [45/120]

draft-ietf-pce-pcep-inter-domain-p2mp-procedures

- No comments.

3.2. Hierarchical PCE Framework (Daniel King, 10 min) [55/120]

draft-ietf-pce-hierarchy-fwk

- No comments.

3.3. PCEP Extensions for Hierarchical PCE (Oscar Gonzalez de Dios, 10 min) [65/120]

draft-zhang-pce-hierarchy-extensions

- Authors were asked if the solution is advertising a variety of path attributes. The response was that the solution provides a mechanism to reduce optimize the information used for H-PCE.

3.4. Representation of Domain Sequence (Dhruv Dhody, 10 min) [75/120]

draft-dhody-pce-pcep-domain-sequence

- Co-chair recommended that options can be documented in the draft and the WG can be used to identify the optimal mechanisms. At this point the emphasises of the document is option 1.

3.5. Forward-Search Path Computation (Huaimo Chen, 5 min) [80/120]

draft-chen-pce-forward-search-p2p-path-computation

draft-chen-pce-forward-search-p2mp-path

- Co-chair highlighted that currently the work has not gained significant support to justify the ID’s becoming a WG effort. The author was reminded that they should look to build a strong technical argument for the solution and highlight gaps with existing solutions.

4. Stateful PCE

4.1. PCEP Extensions for Stateful Control (Edward Crabbe, 15 min) [95/120]

draft-crabbe-pce-stateful-pce

- Author mentioned they plan to review use cases.

4.2. PCEP Notification for States Synchronization (Kexin Tang, 5 min) [100/120]

draft-tang-pce-stateful-pce Comments

- Author was advised to review the solution use cases and see if common ground exists with previous solution.

5. MPLS Applications

5.1. PCEP Extensions for Associated Bidirectional LSPs (Wenjuan He, 10 min) [105/120]

draft-he-pce-pcep-associated-lsp-extensions

-  Author was advised to review what is currently available and identify gaps.

5.2. PCEP Extensions for Service-Aware LSPs (Dhruv Dhody, 5 min) [110/120]

draft-dhody-pce-pcep-service-aware

- No questions.

5.3. PCEP Extensions for Backup End Nodes (Huaimo Chen, 5 min) [115/120]

draft-chen-pce-compute-backup-ingress

draft-chen-pce-compute-backup-egress

- Co-chair reminded author that PCEP extensions should be progressed after dependent protocol extensions have reached sufficient maturity and status in other relevant working groups.
