All, I am sending this out just in case it makes the agenda. You will have seen some of the slides before, but I think they are needed to frame the decision point.

Issues for next NSI call
by Henrik Thostrup Jensen 22 Jan '13

22 Jan '13

Hi. As promised, here a number of issues, which I think we need to decide on. Please read them and understand the subject, so we don't have to spend most of the call explaining the issue itself. Please write if you would like to explain something before the meeting. * NML format decision We need to decide on a format for topology exchange (note that the model for all these are NML, is is just about the specific format). Options are: XML, OWL, N3 (unless we want to invent something). OWL and N3 are RDF based, where as the XML is a direct NML representation in XML. See the NML spec for XML and OWL examples. OWL and N3 examples can be seen in the autogole-topology repository at: https://github.com/jeroenh/AutoGOLE-Topologies/tree/nsiv2/goles All of the formats need to be augmented slightly for describing NSAs, but that is more or less trivial in all of them (and roughly the same procedure). Personally I like the XML representation is it the one most close to the actual mode, and seems easy to generate and parse. * Do we allow one NSA (by URL) to act for multiple networks This isn't clear and does affect some things in the protocol design. Personally I think this is way more trouble than it is worth, and it is easy to create different URLs for each NSA even if they are hosted within the same daemon. * Do we allow multiple NSAs for a single network Could potentially be used for redundancy. In case we allow them, should the NSAs have different identity or the same? * WSDL clean up Remove superflourous NetworkIdType and saml import ogf_nsi_connection_types_v2_0.xsd I don't expect any objections here. * Decide on SOAP 1.1 or SOAP 1.2 for NSI2 This affects requests (slightly), processing and SOAP Faults. It appears that most are on SOAP 1.1 (at least from the faults I have seen). * ServiceExceptionType variables ServiceExceptionType has the following variables decleration: <xsd:element name="variables" type="tns:VariablesType" /> Could we get minOccurs="0" on this, as not all exceptions are necessarely related to a variable. * Orientation In the WSDL we allow STPs to be specified without an orientation. What is the semantics for an STP without orientation? * Connection Identifier We currently have no good way of making an identifier for a connection (it is scoped within the requester identity). This means that there is no way for one entity to pass a connection reference to another. The easiest way to get this it allow NSAs to scope connection ids independently of requester identity, which means that a connection id at an NSA is always the same. This should allow us to create a URN for it at least. The real solution is to have a URL, but since we don't use a protocol where URLs are first-grade citizens that would require a major re-design.

OpenNSA with NSI2 up at nsi.nordu.net
by Henrik Thostrup Jensen 15 Jan '13

15 Jan '13

Hi (since we don't have an NSI implementors list) So, better late than never. But OpenNSA should support NSI2 more or less now. I have an instance up and running for testing: URL: http://nsi.nordu.net:9080/NSI/services/CS2 Network: nordu.net:2012:ets Ports: bi-ps bi-nordu-netherlight bi-nordu-uvalight All ports should accept (and require) labels like this: <labels> <attribute targetNamespace="http://schemas.ogf.org/nml/2012/10/ethernet#" type="vlan"> <value>1782</value> </attribute> </labels> Though the targetNamespace might be optional. VLAN range 1780-1783 is accepted. It is possible to specify candiates like source vlan 1781, dest vlan 1780-1783 etc. It isn't hooked up to any hardware just yet (TLS will also have to be enabled for that). If you have a client, feel free to give it a whirl. Please let me know of any result, especially if something does not work. Known issues: Query is not implemented (yet). Aggregation does not work (path finding with labels not implemented yet). No modify (don't expect this any time soon). Request with label ranges will fail with cannot connect STP to itself if port and ranges are the same (label support isn't quite implemented everywhere yet).

Query request
by Jeroen van der Ham 15 Jan '13

15 Jan '13

Hi, While thinking about a demonstration scenario for SC, we came upon an interesting use-case for the query command. We are trying to plan workflows on the infrastructure, depending on availability. For that it would actually be useful to know not only if a certain resource is in use, but also when it could become available again. Would it be possible to add capabilities for the query command to provide something like that? Jeroen.

NSI tutorial in january
by Jerry Sobieski 14 Jan '13

14 Jan '13

Hi all- I want to propose a "hands on" NSI v2 tutorial for the Techs In Paradise (TIP) 2013 meeting in Honolulu in mid January. I want to present NSI overall as the primary focus of the tutorial (not just v2 features.). Of course this will include the framework, the protocol, some internals, tools, scripting, topology development, etc. We will use v2 as the base for exercises - v2 should be fairly well developed by then. I want to utilize the AutomatedGOLE Facility for the exercises. I would also expect this will include some NML material as well. As TIP will be attended primarily by network engineers, I will focus the tutorial primarily towards service engineering and deployment issues. This tutorial will incur a fair amount of organization and prep work (class sizes, program planning, exercise development and testing, etc) I would like to hear of anyone who would be interested in helping to develop and/or present this tutorial. But I don't think it will be a lot of work at the venue - we already have done some of these in smaller settings. I expect the tutorial to be at least 4 hours (half day) - perhaps a full day (6 hours) if we think we can not overwhelm attendees. Please let me know if you are interested in helping present such a tutorial or if you have ideas/suggestions for how we should frame it - and would be willing to sacrifice a day in Hawaii to teach folks about NSI:-) We have only a short time to get the proposal in, so let me know asap. Thanks Jerry
