WSDLs updated
by John MacAuley 26 Jul '13

26 Jul '13

People, I have updated the WSDL with the service decoupling changes and modified the namespace to reflect the final version (I hope). The updated namespaces will help with the WSDL incompatibilities we are now seeing in testing. Updates are in the code.google repository. For those people using Java you will need to update your imports if you are using the namespace as a package name. Also, you will need to separately compile the service schema using jaxb. John

Issue 98 in ogf-nsi-project: Decouple service specific schema from NSI-CS core schema
by ogf-nsi-project＠googlecode.com 26 Jul '13

26 Jul '13

Status: Accepted Owner: jmacauley Labels: Type-Defect Priority-Medium FoundInVersion-2.0 FixedInVersion-2.0 New issue 98 by jmacauley: Decouple service specific schema from NSI-CS core schema http://code.google.com/p/ogf-nsi-project/issues/detail?id=98 Description of Issue: See document "NSI-CS Service Decoupling v5", July 26th, 2013 for in-depth discussion of issue and agreed solution. In NSI CS version 1.x and 2.0 only unidirectional and bidirectional point-to-point services are offered as part of the protocol. In fact, the NSI working group violated most common protocol design principles by hard coding the service offering directly into the core protocol specification, when in fact, the NSI CS protocol was meant to support many service types. Discussion of Issue: Our primary goal should be to remove the dependencies of service specification from the core NSI CS protocol. This will allow the existing NSI CS protocol to remain stable while permitting changes to the services offered by NSA within the network. Fortunately, with XML and a small change to the structure of our existing NSI CS protocol we can achieve this exact behavior. Resolution of Issue: The proposal is to remove the point-to-point specific bandwidth, path elements from the criteria element and place them into a separate service specific schema definition with its own dedicated namespace, and add an ANY child element to the criteria element to allow generic inclusion of external service specifications. With this new ANY child element we also remove the need for the serviceAttributes element as the capability is incorporated into the base criteria element. -- You received this message because this project is configured to send all issue notifications to this address.

Topology bootstrap file
by Jeroen van der Ham 25 Jul '13

25 Jul '13

Hi all, I have just created a topology bootstrap file for the Automated GOLE demonstration. Please let me know what you think about this. The syntax is not completely final yet, because I have to figure out some details on how to define this in a schema. But ultimately it will have to be something along these lines as it has to contain: - a global topology, - the identifiers for each of the participating topologies, - the URL for the topology file of each topology. Jeroen.

Adding an attribute
by Jeroen van der Ham 25 Jul '13

25 Jul '13

Hi, I realised today that I never included a definition for URL references in the topology definition. We have had a discussion about this in the NML group, and it was decided that this is a control-plan construct and would not be added to NML. So, for the NSI extension I am proposing to add an attribute to Network Object "isReference" which has a URI as value which points to a topology file that contains more information on that object. This attribute would be defined in the NSI extension schema. Now, if everyone agrees, I have a practical question: how do I express this in the XML Schema? The schemas are available here: https://github.com/jeroenh/NSI-Topology/tree/master/schemas Jeroen.
