Loa on Shepherd's report on dynamic ms pw draft May not normally do reporting on shepherds activities but this time not part of wg leadership so wanted to give an update. All involved in the WG are involved in the draft so needed someone with a fresh look external person from wg not unusual to appoint as shepherd shepherd review slide -17 folks on draft including the Chairs bad example of merging a few drafts Loooooooooong list of nits many result from the merging of drafts. first draft from 2006 and indiv drafts from 2004.... a decade of work IPR poll slide real problem 20 co-authors Hard to find authors since work has lasted so long can't remove person from author list - that wouldn't work each author has influence such that their IPR could be ncluded and then not disclosed Matthew: 2 outstanding responses, a few more came int eh last couple of days yjs: I think that according to the new diversity rules Loa needs to say he or she even if there are no she's on the author list ... David Sinicrope: Most folks accounted for, but some still on vacation Scott Bradner: 20 co-authors but only 3 on first page If they all don't answer Stewart will harass Loa by phone Shepherd Write Up slide given 20 authors support for work should be good Andy: comment from Loa and AD - ANYONE can be a document shepherd If anyone interested, please volunteer. Good training for WG Chair to learn administrative details. Stewart: Also gives person some visibility. Shepherd ensures that authors address comments and chase them down. Keyed IPv6 Tunnels - Wim Slide 1 - filling in for Giles David Sinicrope: Draft not for PW working group.. Should be on L2TPEXT working group. However given PW expertise here decided to present here. can work without the session ID. Described in the draft Use PW OAM mechanisms for failure detection comment on L2TPEXT mailing list solution implemented by multiple vendors and deployed. Informational draft Andy: if its deployed why infomrational rather than standards track? Wim: because we don't change any protocol, just show the way it is used. David Sinicrope: I'm up Andy Malis: I'll be taking minutes David is presenting the liaison from SG15 Q10 and Q12 The figure is the important part The questions noticed that there's not much clarity on which combinations of p2p SS and MS PWs and p2mp PWs are valid Greg Mirsky - Ne needs a clarification - what kind of a PW maps to a P2MP PW, given that in MPLS-TP there may not be an IP return path? yjs: actually p2mp over p2p doesn't make sense, p2p can be p2mp - why not ? (should have been p2p can be OVER p2mp) Andy Malis: Dave - we need to provide additional clarifications in the P2MP requirements draft to what combinations make sense and which don't Dave - additional clarity on these combations would be appreciated Stewart - woudln't the most interesting one be P2P MS SW over a P2MP LSP, which isn't in there? Stewart - so we could make progress on the document, and make it simpler? David Sinicrope: We need to provide clarification of how p2mp pw can be combined with LSPs Andy Malis: A comment that agrees that we need to remove the P2MP MS PW case David Sinicrope: Matthew: Focus on the p2mp ss pw case and should be able to build from that. If that is done, then gives clarity to the models Andy Malis: Stewart - then models 1, 2, and 3 don't exist Dave - They don't explicitly ask for a response, but the clarification provided by December would be helpful Matthew- we'll work on a response with the editors of the P2MP editors David Sinicrope: Editors of the p2mp should draft a response for the Dec Q12 meeting Andy adjourned the meeting. And we're done! ********************************************************************** Overflow (Will be presented if time permits.) ********************************************************************** xx. - None currently ********************************************************************** REMOTE INFORMATION FOR THE PWE3 SESSION(S) ********************************************************************** Remote Participation Info: http://www.ietf.org/meeting/87/remote-participation.html - No WebEx - Audio will be on: http://ietf87streaming.dnsalias.net/ietf/ietf876.m3u - Jabber room is "pwe3"
