  2. History/Background And Progress So Far

  3. draft-papneja-mpls-protection-meth-merge • After an overwhelming support on the list 2 complementing methodology drafts were merged • All the comments to the 2 drafts were addressed in the merged draft • Methodology for benchmarking MPLS Protection mechanisms • draft-papneja-mpls-protection-meth-merge-00.txt

  4. Feedbacks on FRR Protection Meth Draft: So far So Good • Overall there seems to be great amount of interest in this work • As more and more ISPs consider deploying this feature, they are looking towards a uniform methodology and terminology across multiple FRR implementations • Many comments on Traffic Generation section • Requests to provide more information on failure detection times (may not be negligible) • Need to describe about RSVP refresh along backup path • Suggestion to add background traffic • When talking of # of labels need to specify where • BFD timer info missing in reporting format • Significance of having large number of scenarios • Nits, Some more clarifications and other editorial work • Recommendation to highlight importance of correlated failures

  5. Highlights of merged draft • Retain the key elements of both drafts • draft-vapiwala-bmwg-frr-failover-meth-00.txt • draft-poretsky-mpls-protection-meth-05.txt • Avoid any duplicate test cases or procedures • Incorporate comments received for both the drafts • Simplify topologies • Total of eight scenarios presented in the merged draft • Use common terminology as defined in • Draft-poretsky-protection-term-02.txt • Incorporates all the received on this item • Including the responses received for the proposal

  6. Current Status • Current Status - Waiting to hear from WG Leadership on the Acceptance of the Work Item • As per previous meeting minutes • Appears more than significant interest in the BMWG working • The interest has reached its peak • 70% of attendees in the last meeting supported the work item • The authors submitted the official proposal on May 3 and call for support ended June 2, 2006 • No negative support received • Overwhelming support on the mailing in favor of making this as work group item • Merged draft was submitted on June 19th, 2006 • Current Milestones • "Terminology For Protection Benchmarking,“ - draft-poretsky-protection-term-02.txt, • Ready for WGLC 07/06 and Ready for IESG 11/06. • "Methodology For MPLS Protection Benchmarking,“ - draft-papneja-mpls-protection-meth-merge-00.txt • Submitted 06/06 and Ready for WGLC 11/06 • Ready for IESG 04/07

  7. Acknowledgements • Thanks to BMWG-ers for support shown in the work item • The authors wish to thank the following for their invaluable input to the merged document • Curtis Villamizer • Jean Philip Vasseur • Karu Ratnam • Arun Gandhi • We would like to thank Agilent for their review of this draft and execution of the methodology to ensure its correctness
