2 Scope of Work Item Common terminology and metrics for benchmarking the performance of sub-IP layer protection mechanisms Benchmarks are measured at the IP-Layer Methodology is technology-independent so can be used to compare performance of different protection mechanisms Terminology will applied to separate Methodology documents for different sub-IP layer protection mechanisms  Multi-Protocol Label Switching Fast Reroute (MPLS-FRR)  Generalized MPLS (GMPLS)  Automatic Protection Switching (APS)  Virtual Router Redundancy Protocol (VRRP)  Stateful High Availability (HA) Drafts currently available for review  draft-ietf-bmwg-protection-term-04.txt  draft-ietf-bmwg-protection-meth-03.txt

3 Current Status/Update Under re-review by all the co-authors  Incorporating comments from the group  Soliciting more comments on the existing documents  No new updates for the IETF-72 since none of the co-author could make it Next versions of the Sub-IP Protection Meth and Term to include the following changes  Formatting  Editorial changes  Splitting the Introduction in the terminology document into two sections: Introduction and Overview  Optimizing the usage and reference to figures/test setups  Recent comments from Bill Cerveny (Thanks to him for his thorough review and comments of the terminology doc)

4 Next Steps Incorporate any new comments from meeting and mailing list  Version 4 of methodology document will be submitted soon  Version 5 of the terminology document will be submitted soon Seek direction from the working group on firming up the progress of terminology document as lot of time and reviews have already been performed
