Issue 52 in ogf-nsi-project: time-out time - how to set timeouts

Status: New Owner: guy.robe...(a)gmail.com Labels: Type-Review Priority-Medium FoundInVersion-1.0 FixedInVersion-1.1 New issue 52 by guy.robe...(a)gmail.com: time-out time - how to set timeouts http://code.google.com/p/ogf-nsi-project/issues/detail?id=52 Description of Issue: TK: how do we set time-outs? Discussion of Issue: JS: possible option is to add heart-beat message RHJ: does not recommend putting the onus on the user to determine time-out Henrik: no easy solution with current protocol design. Suggest that we could have policy on expected response times...? Jeroen: currently reservation requests can take around 1 minute and up to 2 minutes for provisioning. So we are often getting time-out issues in demo. JE: proposes using the existing query to check state. Radek: Need to add timer definition to the state machine to make this work Resolution of Issue: Some kind of exchange between RA and PA needed to find if PA is still processing request correctly. No clear resolution to this issue, needs further investigation

Discussion of Issue: TK: could add a large burden of unnecessary messages? Resolution of Issue: The implications of the change needs to be reviewed.

Issue 48 in ogf-nsi-project: Addition of a Failed state into the state machine.

Status: Accepted Owner: jmacau...(a)gmail.com Labels: Type-Defect Priority-Medium FoundInVersion-1.Rio FixedInVersion-1.1 New issue 48 by jmacau...(a)gmail.com: Addition of a Failed state into the state machine. http://code.google.com/p/ogf-nsi-project/issues/detail?id=48 Description of Issue: There is no way within the existing NSI state machine to determine if a reservation in the "Terminated" state reached that state through a successful execution or through a failure. Discussion of Issue: For example, a reservation is modelled by a state machine once a reserve.rq is sent and the state machine transitions from the "Initial" to the "Reserving" state. If the reserve.rq fails the existing state machine transitions into "Cleaning" and then to a final rest state of "Terminated". Likewise, a successfully executed schedule reaches the final rest state of "Terminated". An observer using the query operation would not be able to distinguish the failed schedule from the successful schedule after the fact. It can be even more confusing in that one schedule may have failed do to a second schedule, but there is no way to tell which after they have completed. There are two possible solutions: 1. Add a new "Failed" state to the state machine. 2. Add an informational field to the state machine / reservation record that tracks the reason for transition into the "Terminated" state. We could model a successful schedule that reached endTime. A manual terminate. A forcedEnd received from a child or local NRM. A reservation failure (could store the ServiceException). I do not believe the argument that this is an OAM issue and needs to be solved separately is valid in this case. We need additional information. Resolution of Issue: I would recommend option #2.

Issue 42 in ogf-nsi-project: Query details and summary
by ogf-nsi-project＠googlecode.com 07 Dec '11

Status: Accepted Owner: ---- Labels: Type-Defect Priority-Medium FoundInVersion-1.0 FixedInVersion-1.1 New issue 42 by thost...(a)gmail.com: Query details and summary http://code.google.com/p/ogf-nsi-project/issues/detail?id=42 I don't quite understand why we cannot just have one query mode, instead of the Summary and Details mode. Why not just have a single mode, which returns all the information? AFAICT none of the information requires a recursive query. Furthermore the current scheme actually prevents one from getting the current connection state and the list of children, which is rather unfortunate as that is exactly what I would like to have for the connection visualization tool. Is there any reason these two modes cannot be conslidated into one?

Re: [Nsi-wg] NSI abstract at TNC'12
by Radek Krzywania 01 Dec '11

01 Dec '11

Hi all, In the attachment there is "final" version of the document, including all changes. We exceeded 1200 words limit by over 100 so I needed to cut some parts. The main change is the cut of the paragraphs on NSI agents (RA and PA), which did not bring much new to the abstract. I get down to 1199 :) I've already submitted this version just in case, but it is still possible to update it at any time before 5pm. So if anyone have some more comments - please speak now, or forever hold your peace. Again - authors please double check addresses and affiliations. And if someone has copies of two referenced documents, please check the references.
