UvA/TUD topology exchange proposal
by Ralph Koning 19 Sep '14

19 Sep '14

Hello all, During the meeting in Atlanta and in several of the NSI calls the University of Amsterdam and Delft University of Technology announced that they were also preparing a proposal for exchanging topologies combined with path finding. Attached to this mail is the document describing this topology exchange, and a small discussion on how we can apply it to the NSI work. Feel free to comment and ask questions. Regards, Ralph (UvA) and Farabi (TUD) -- Ralph Koning SNE research group, University of Amsterdam Tel: +31 20 525 7928 | http://staff.science.uva.nl/~ralph

Preparation for NSI @ NORDUnet conference
by Guy Roberts 17 Sep '14

17 Sep '14

Hello All, I would like to remind everyone that the next face-to-face NSI meeting will be held on the 22nd September in Uppsala. To ensure that this meeting is productive we can only consider written proposals that have been submitted in advance of the meeting. To ensure that everyone has a chance to read through the proposals these should be sent to the NSI mailing list 2 weeks before the meeting. The following documents will be up for discussion: Draft document distribution service: https://redmine.ogf.org/dmsf_files/13243 Draft NSI AA: https://redmine.ogf.org/dmsf_files/13324 Draft NSI topology exchange: https://redmine.ogf.org/dmsf_files/13323 Draft Reachability based topology: https://redmine.ogf.org/dmsf_files/13254 If you would like your proposal to be considered don't forget to send it to the mailing list by the 8th September.

NSI AA draft v5
by Hans Trompert 27 Aug '14

27 Aug '14

Hi all, Both John and Henrik provided feedback on v4 of the document (thank you very much!), and the three of us had a vivid email discussion earlier this month on why and how to structure the security attributes in the NSI message header. The discussion is not finalized, but I updated the document with the latest ideas. Please find attached version 5. This document is still far from finished. Big question still remains: how does the group wants to move forward with this document? Cheers, HansT.

No NSI call tomorrow Aug 13, 2014
by Chin Guok 12 Aug '14

12 Aug '14

Hi all, Due to several folks being on vacation, and NSI documents still in progress, I suggest that we cancel tomorrow's NSI meeting. If someone has an urgent issue that cannot wait and can't be done via email, please speak up. Just a gentle reminder that we are about 5+ weeks away from the NSI meeting in Sweden. For folks who have a proposal or a discussion that they would like to have, please send it to the NSI mailing list so that we can add it to the NSI face-to-face meeting agenda. Also, for discussions that need a decision point at the face-to-face meeting, please send out documentation for review no lather than September 10th. Thanks! - Chin -- Chin Guok NOC: (510) 486-7600 Network Engineer (800) 333-7638 ESnet Network Engineering Group (AS293) Lawrence Berkeley National Laboratory

OGF NSI networking architecture and need for certificates with restricted user base
by Sill, Alan 07 Aug '14

07 Aug '14

Dear folks in the OGF CAOPS, VOMS-PROC and NSI working groups. I'd like to initiate some discussion among the participants in these working groups for the use case referred to in the talk at the link below. Some review of the conditions for this use case would be helpful. Note this is also a use case that comes up in Internet-of-Things discussions, and has caused some discussion on the PKIX group list (though that group is now dormant of course) and other related lists lately. To me this is a familiar situation with well-known parameters, but possibly some additional considerations, and might possibly lead to some useful communication among the members in these groups about solutions that could be applied using existing technologies that would avoid the possible downsides associated with the proposed use of self-signed certificates. (For example, extended attribute certificates as used in VOMS, though the same or perhaps through a different implementation, might be a good solution here; other solutions might be contemplated that would be more attractive than self-signed certificates for this situation.) Your comments, discussion and input are recruited (by me -- I'm not speaking for the NIS-WG members per se!), and I hope that all parties will regard this as useful discussion for information exchange only. Thanks, Alan Begin forwarded message: From: Guy Roberts <Guy.Roberts(a)dante.net<mailto:Guy.Roberts@dante.net>> Subject: RE: [Nsi-wg] Wednesday's NSI conf call Date: July 30, 2014 at 1:30:19 PM GMT+2 To: Alan Sill <kilohoku150(a)gmail.com<mailto:kilohoku150@gmail.com>> Hi Alan, Please find the slides on NSI security here: https://redmine.ogf.org/dmsf/nsi-wg?folder_id=6592 The proposal is that NSAs will run their own private Certificate Authorities (self-signing) rather than using public Certificate Authorities. Participating NSAs will then exchange information about each other’s Certificates in an ad hoc way. This solution does not scale well as private Certificates have to be manually shared, but it reduces the size of the certificate pool.
