He provided good feedback and pulled together the attached slide showing the concepts we are trying to capture. I also mocked up an example OWL file with an NSI topology specific name space, and introduced the NSI concepts of NSnetwork, STP, and NSA. These classes are used to model their simplified namesakes from the NSI CS protocol, and are not meant to replace the DTOX definitions, but augment them with our NSI specific concepts. We can consider the NSI topology elements an overlay on the existing DTOX elements, reusing data properties and including references to DTOX object instances. (I removed the DTOX object instances from the file to simplify the example). I think this will become much clearer when running NSI on out real networks and not this abstract topology for the demo. >> >> I have not yet validated the attached OWL so I apologize if it contains errors.

Testing NSI implementations
by Henrik Thostrup Jensen 23 Aug '11

23 Aug '11

Hi everyone, especially developers :-) If we want to have something working in Rio, we need to start testing. To facilitate this, I've a test instance of OpenNSA. The services can be reached at: http://orval.grid.aau.dk:9080/NSI/services/ConnectionService (Aruba) http://orval.grid.aau.dk:9081/NSI/services/ConnectionService (Bonaire) Where you can try to make reservation and so forth at. It only knows about the Aruba and Bonaire networks, but will invoke services at each other. There are still a lot of stuff missing, most notably error paths, so if you try something odd it might blow, but at least we will learn something :-) The log for the OpenNSA is available here if you want to see what is going on: http://orval.grid.aau.dk:9000/opennsa.log I also have a client that can exercise the whole reserve-provision-release-terminate lifecyles and query if you want me to try and interact with your service. You can send the URL to me directly if you don't want to have it public on the list. Again, we cannot wait to test in Rio if we want something that works there. So please give it a go :-). Best regards, Henrik Henrik Thostrup Jensen <htj at ndgf.org> NORDUnet / Nordic Data Grid Facility.

Plugfest participants contact information
by Jerry Sobieski 20 Aug '11

20 Aug '11

Hi all- Attached please find the current info I have received to date regarding Rio NSI Interop participants. We have 7 implementations that have asked to be part of this (!). I will keep this doc updated as additional info comes in, so please let me know if information changes. I will try to put this on a wiki next week. The recent addition of a couple new implementations means that we need to modify the previous Plugfest Guide in regard to test matrix. And there are several other tweeks as well to the Challenges in terms of how we run them - the basic functional tests are unchanged, but how we run them will change a bit to make it easier logistically. We want to clarify and simplify the complexity of the test scenarios - particularly in 3 and 4. These tweeks will also include an enhanced topology model/description that will work better for NSI testing (it is a superset of current set of topo resources. And still uses RDF and OWL.) I will have the updated guide available in a day or two. In the meantime, I encourage the teams to proceed with testing Challenge #1. And when you are confident that is working, move on to to Challenge #2 with *any* other teams that have completed #1 as well and are ready to do cross implementation tests. (In challenge #2, the pairing of teams was arbitrary, so feel free to test with any other implementation that is ready.) The contact info below should allow everyone to contact each other. Also, if you are ready to do Challenge #2 with another imlementation, please post that to the list so we can see and monitor progress. Thanks all! Jerry 1. AutoBAHN (GEANT) 1.

WSDL update
by John MacAuley 16 Aug '11

16 Aug '11

Peoples, Please find attached the latest revision of the WSDL and XSD files. There were a large number of changes incorporated based on the feedback from OGF 32, so please take some time to have a look through. The WSDL compiles, but I have not programatically verified the changes. Please let me know if I have missed or broken anything. John. Version 0.07 Changes to NSI WSDL specification Date: July 29, 2011 Author: John MacAuley Notes: These are changes requested at OGF 32 working group meeting. 1. Created a QueryFailedType to provide a specific type without revervation specific information. 2. Renamed transactionId to correlationId and added the correlationId to the SOAP output response (acknowledgement). 3. Changed globalReservationId to be xsd:anyURI and mandatory but permit it to be nillable. This will allow an OGF URN (reference artifact 6478 "Procedure for Registration of Sub-namespace Identifiers in the URN:OGF Hierarchy") to be used for compatibility with other external systems. 4. Restructured confirmed and failed parameters. 5. Renamed GenericResponseType to GenericAcknowledgmentType. 6. Renamed all WSDL output "Response" messages to "Acknowledgment". 7. Fixed type issue with ProvisionFailedRequestType. 8. Removed the versioning information from WSDL port type names and bindings. 9. Removed connectionState from generic confirmed and reservation confirmed message since the state should be implied. 10. NSA identifiers are now defined as xsd:anyURI to hold an OGF URN. 11. STP definition is now changed to be a xsd:anyURI to hold an OGF URN (urn:ogf:network:stp:<NSnetworkid>:<localid>). 12. Removed the query option in QueryFilterType for search based on connection state. 13. Renamed PathObjectType to PathType. 14. Removed NetworkIdType, LocalIdType, and ServiceTerminationPointGroup since no longer needed. 15. Renamed orderedStpList to stpList as requested since "List" implies "Ordered." 16. Modified the XSD definitions to do local imports and copied the needed external XSD locally to package with NSI definitions. 17. Lined up naming of operations in XSD with specification and associated types to help avoid type name conflicts (ReservationRequestType and QueryRequestType). 18. Simplified the interface portType definitions by defining a single acknowledgment message type for output. 19. Moved directionality of the service into the path object since this is an attribute of the path. 20. Moved path object out of service parameters to allow for different path definitions between the reservation request and the reservation response/query results. 21. Added DetailedReservationInfoType and DetailedPathType to allow for connection tree to be return in the reservation response and query response. This is the groundwork for implementation to provide more detailed connection information and recursive queries (future release). 22. Segmented service bindings into requestor and provider messages sets to help with code modularity and provided proper endpoint definition for RA and PA. This required restructuring of the interface file as well, and moving of the portType definitions into the service bindings. The NSI requestor SOAP endpoint "ConnectionServiceRequestor" contains definitions for: reservationConfirmed reservationFailed provisionConfirmed provisionFailed releaseConfirmed releaseFailed terminateConfirmed terminateFailed query queryConfirmed queryFailed forcedEnd The NSI provider SOAP endpoint "ConnectionServiceProvider" contains definitions for: reservation provision release terminate query queryConfirmed queryFailed Open Issues for after GLIF bake-off in Rio: 1. Need to add the security policies to the WSDL so we can sign the messages to validate authenticity. This will not impact the core schema but will impact the WSDL definitions. 2. Per conenction reservation user/security information in a query response. ---------------

Constructing STP from topology data.
by John MacAuley 16 Aug '11

16 Aug '11

Jeroen, Jerry, Can someone show me an example of how we will be mapping the abstracted topology provided for the interoperability tests. Sorry if this was already discussed, but I can seem to remember the thread. My guess would be that we are treating GOLE objects as networks and Port objects as the local part? I would therefore have the following STP address: urn:ogf:network:stp:Aruba.Loc:Aiden Do I have this correct? Thanks, John.

CFP: The Network-aware Data Management Workshop (NDM 2011) to be held in conjunction with SC 2011
by Inder Monga 12 Aug '11

12 Aug '11

Sharing an interesting CFP for a workshop to be held during SC2011, please feel free to share with your colleagues. Sorry if you receive duplicate requests. Inder ----------------------------------------------------------------------------------------------------- CFP: The Network-aware Data Management Workshop (NDM 2011) to be held in conjunction with SC 2011 Mon Nov 14th, 2011 - Seattle, WA (8:30am - 5:00pm) The Network-aware Data Management Workshop (NDM 2011) will be held in conjunction with the IEEE/ACM International Conference for High Performance Computing, Networking, Storage and Analysis (SC 2011), in Seattle, WA. The format will consist of 30 minute presentations of peer-reviewed papers. Accepted papers will be published in ACM or IEEE digital proceedings through SC'11. Scope: Accessing and managing large amounts of data is a great challenge in a collaborative environment where resources/scientists are geographically distributed. There is a need for efficient use of the network infrastructure in order to address the increasing data and compute requirements of large-scale applications. Since the amount of data is continuously growing, traditional techniques of leaving the burden on the user of moving/storing data is not a viable option in many cases. In order to deliver true exascale performance to the application layer, network-aware data management services for resource provisioning, intelligent data-flow and coordination between the host systems is highly desirable. This workshop will seek contribution from academia, government, and industry to discuss emerging trends in use of networking for data management, novel abstraction techniques for data representation, simplification of end-to-end data flow by providing transparent data services, end-to-end resource coordination, and network-aware tools for the scientific community. One "Best Paper" would be awarded for outstanding contributing to the field of large-scale data management across network. In addition to that, two "Best Paper Honorable Mention" would be awarded.

NSI CS WSDL and state machine v1.0 are available now for plugfest
by Guy Roberts 11 Aug '11

11 Aug '11

The WSDL and state machine for version 1.0 of the NSI Connection Service have now been frozen for the NSI plugfest. These can be found here: http://forge.gridforum.org/sf/docman/do/listDocuments/projects.nsi-wg/docma… Please be aware that this version is subject to errata if any show-stopper issues are found during development; these changes will be kept to a minimum to avoid disruption to prototype development. Happy coding and I look forward to a great plugfest in Rio!

GLIF Rio Plugfest Guide
by Jerry Sobieski 11 Aug '11

11 Aug '11

Hi all- Attached please find the GLIF 2011 Rio NSI Plugfest Guide v1.0. THis is fairly detailed, but it is meant to be very clear and even handed about NSI interoperability. This document includes four technical interop Challenges. Also attached please find the RDF (.OWL) files for the topologies that I use in the Challenges. You should be able to just upload these into the SNE editor to view them. These files describe a single self-contained inter-domain topology for the associated Challenge(s). The "Deuce" topology is for Challenge 1 and 2, the "Quad" topology is for Challenges 3 and 4. Please review and offer any comments or suggestions. These are drafts - I expect some [hopefully] minor adjustments to these over the next couple weeks. But I hope this is essentially on the right track to guide the implementations towards a successful interop in Rio. Thanks Jerry

WSDL version 0.09
by John MacAuley 10 Aug '11

10 Aug '11

Peoples, Here is the latest (and I hope the last) update to the WSDL. John. Version 0.09 Changes to NSI WSDL specification Date: August 6, 2011 Author: John MacAuley 1. Changed all occurrences of Requestor to Requester in the documentation, names, and bindings. 2. Capitalized enumerated values in DirectionalityType to "Bidirectional" and "Unidirectional". 3. Set directionality default to "Bidirectional". 4. Added connectionState to DetailedPathType so each NSA down the tree will provide its view of the state machine. 5. Modified ReservationConfirmedType to return only summary reservation information and not the detailed path. 5. Created new QueryOperationType with values "Summary" and "Details" to allow modeling of two separate query operations. The "Summary" operation matches the behavior of our original query on level deep in the tree, while "Details" performs a recursive query down the tree to build a complete path view from all children. 6. Modified the QueryFilterType to use QueryOperationType allowing the requester to specify if summary or detailed path results should be returned. 7. Restructured the QueryConfirmedType to support returning of a choice of summary reservation information or detailed path results. 8. Created QuerySummaryResultType to hold the query summary results. 9. Removed DetailedReservationInfoGroup to QueryDetailsResultType to hold the recursive path query results. 10. Modified QueryConfirmedType to return a choice of reservationSummary or reservationDetails. 11. Removed AttributeSequenceType and replaced with saml:AttributeStatementType to avoid naming conflicts with AttributeType definition with exists in both namespaces. 12. Removed SubjectAttributeSequenceType and replaced with equivalent saml:AttributeStatementType. ---------------
