ifModifiedSince/lastModified

Guy, I looked at the NSI 2.0 to 2.1 delta document and it states the following for last modified queries: o Last modified queries § Add ifModifiedSince element to QueryType § Add lastModified element to QuerySummaryConfirmedType, QueryRecursiveConfirmedType I had thought that after we left Prague the agreement was not to add is capability to the QueryRecursiveConfirmedType do to the complexity and issues with not being able to simultaneously query the request tree to get an accurate lastModifed data set? Can anyone else remember the final decision? Thanks, John

Jens, The NSI working group has decided that we would like to take time out to concentrate on NSI implementations and learn from these. There is no appetite among our working group members for a big push to a version 3 NSI at this time. We may pick this up again if some clear needs arise out of our implementation experience. Guy -----Original Message----- From: Jensen, Jens (STFC,RAL,SC) [mailto:jens.jensen@stfc.ac.uk] Sent: 23 March 2016 14:54 To: Guy Roberts; Jerry Sobieski; nsi-wg(a)ogf.org Subject: Re: [Nsi-wg] Wednesday's NSI conf call Hi Guy, Thanks for that. It seems a shame to wind the group down as there seems (to me) to be so much to do. With IoT and "fog computing" (oh dear) networking is going to increase in importance over the coming years, one would have thunk. Also the big questions like the "Science DMZ" Anyway in the first instance I will liaise with Jerry to connect him - plus everyone else who is interested, of course - to the BEACON folks and we can then see what they think.

Modify behaviors
by John MacAuley 14 Mar '16

14 Mar '16

Peoples, Hans and I have been working through behaviours of the Modify operation as the NSI CS document is a little vague on some of the more detailed aspects of the operation. Our most recent discussion focused on the modification of startTime. For example, let us say reservation X has a startTime of "now + 1 hour", but I would like to modify the startTime to start "now". In an initial reservation request we specify at startTime of now by omitting the <startTime> element, however, for a modify operation we cannot distinguish from a startTime not specified for modification and the startTime intentionally missing to indicate "now". In the current schema definition we cannot use an empty <startTime> element as it is an illegal xsd:dateTime. So that only leaves us with the option of specifying a <startTime> reasonably close to now, but well all now how troublesome this is with our current implementations. There is a solution to this issue. If we modify the existing schema to allow for the "nillable" option on startTime we can now specify an empty <startTime xsi:nil="true" /> element to handle this "start time of now" case. This would require a non-backwards compatible change for modify, but I am not sure how may NSA implementations of modify exist. The second issue is what happens if in the modify request a parameter with the same value is provided? Do we fail the modify or continue with the same value? For example, if a modify is received with the same startTime but a different endTime do we reject to modify since it contains the same startTime, or do we accept the modify and only change the endTime? I would assume we accept the modify operation an proceed with modification of endTime. What happens if only one parameter, say capacity, is specified and it contains the same value as the current reservation version? Thanks, John

NSI policy document
by Guy Roberts 10 Mar '16

10 Mar '16

Hello All, You will recall that last year Richard HJ reviewed the NSI policy document and a round of edits were made. Then over the past few months we have reviewed the NSI policy approach and made some refinements. This is now all reflected in the latest version of the document which you can download here: https://redmine.ogf.org/dmsf_files/13420 I will open a request for the OGF to put this into public comment.
