The MPLS WG Archive

["O'Connor, Don" <don.oconnor@us.fujitsu.com>]

I do not support draft-bryant-pwe3-mpls-transport-00.txt as a WG draft for the following reasons

1) Transport MPLS as pursued by ITU encompasses functionality that overlaps work in multiple IETF WGs. A minimum subset is PWE3 and MPLS. Work in CCAMP is also most probably relevant. Without companion work in the MPLS WG on a T-MPLS implementation profile, draft-bryant-pwe3-mpls-transport-00.txt serves no useful purpose

I suggest that a first necessary step is that the appropriate Area Directors consider whether or not they want to take on the entire task of generating a complete Transport MPLS implementation profile based on current RFC / ID / extensions and doing it right and comprehensively. WG charters should be updated appropriately

In its present form draft-bryant-pwe3-mpls-transport-00.txt is an incomplete attempt at addressing a portion of what ITU SG 15 and ITU SG 13 are pursuing for Transport MPLS

If IETF leadership decides that they would like to pursue a comprehensive Transport MPLS implementation profile, it should be done in cooperation and coordination with leadership in ITU SG 15 and SG 13. I would support such as effort if it is done in this context. To date draft-bryant-pwe3-transport-00.txt does not fall into this category

2) draft-bryant-pwe3-mpls-transport-00.txt does not adequately address Transport MPLS OAM and Protection Switching requirements

2A) Protection Switching - linear protection switching coordinated by an appropriate OAM protocol is required. It is necessary to meet the requirements of G.8131

2B) Current pseudowire VCCC OAM lacks - Maintenance Entity Levels, MEP / MIP, AIS / RDI, PM measurement. It is necessary to provide the functionality being developed for Y.17tom

Don

Folks,
As discussed in the meeting, I'd like to solicit WG feedback on
adopting this as a WG document.   If you're in favor or opposed
to adopting this please speak up now.
