Draft NML for Service Domain and Adaptation
by John MacAuley 03 Dec '13

03 Dec '13

Peoples, I have attached an XML document that uses the SwitchingService, AdaptationService and DeadaptationService to model the concepts of NSI Service Domains and Adaptation. This uses a modified NML NSI-EXT schema that is not yet approved (it is also included). Although syntactically correct, I am not 100% sure it will meet our needs until i try to build a path finding graph using the new information. i will try to do prototype this week. John.

Adaptation
by John MacAuley 28 Nov '13

28 Nov '13

All, I had an action item to determine the NML mappings for the Service Domain and Adaptation objects. For the Service Domain object I would recommend proceeding as we were with the Transfer Function and use the NML SwitchingService to model the capability. It allows Ports and PortGroups to be specified which is what we need. We will need to work out if the service type gets specified in the SwitchingService or the individual Port/PortGroups. <nml:SwitchingService id="urn:ogf:network:example.net:2012:nodeA:switchingService"> <nml:Relation type="http://schemas.ogf.org/nml/2013/03/base#hasInboundPort"> <nml:Port id="urn:ogf:network:example.net:2012:nodeA:port_X:in" /> <nml:Port id="urn:ogf:network:example.net:2012:nodeA:port_Y:in" /> </nml:Relation> <nml:Relation type="http://schemas.ogf.org/nml/2013/03/base#hasOutboundPort"> <nml:Port id="urn:ogf:network:example.net:2012:nodeA:port_X:out"/> <nml:Port id="urn:ogf:network:example.net:2012:nodeA:port_Y:out"/> </nml:Relation> </nml:SwitchingService> Unfortunately, we have a slight issue with the Adaptation. The NML AdaptationService object supports references to Ports and PortGroups, however, it does not support references to SwitchingServices. This is due to the fact that Adaptation is built around the concept of adapting between ports. As you can see below, we have a port with an associated AdaptationService. The AdaptationService references the target port of the adaptation. <nml:Port id="urn:ogf:network:example.net:2012:port_X:in"> <nml:Relation type="http://schemas.ogf.org/nml/2013/03/base#hasService"> <nml:AdaptationService id="urn:ogf:network:example.net:2012:port_X:in:adaptationService"/> </nml:Relation> </nml:Port> <nml:AdaptationService id="urn:ogf:network:example.net:2012:port_X:in:adaptationService"> <nml:Relation type="http://schemas.ogf.org/nml/2013/03/base#providesPort"> <nml:Port id="urn:ogf:network:example.net:2012:port_X.1501:in"/> </nml:Relation> </nml:AdaptationService> <nml:Port id="urn:ogf:network:example.net:2012:port_X.1501:in"> <nml:Label labeltype="http://schemas.ogf.org/nml/2013/03/ethernet#vlan">1501</nml:Label> </nml:Port> For this to work we will need to create a port in each Service Domain participating in the adaptation which can then be linked through the AdaptationService. Since this will not form an SDP due to the differing service types, a path finder will not accidentally chose the STP in a path, unless it has specifically understood the adaptation and created the transitional SDP. I am happy with this solution. Comments? Johnnsi

NSI meeting in Oxford
by Guy Roberts 26 Nov '13

26 Nov '13

Hello NSI team, I have requested 6 NSI sessions for OGF40 in Oxford, this will ensure that we have plenty of time to close down NSI CS v2.0. Meeting details are here: http://www.ogf.org/dokuwiki/doku.php/events/ogf-40 I am also planning a dinner in one of the old Oxford colleges (details to be confirmed), could you please let me know if you would like to attend the dinner? NML members are also invited to the dinner. Thanks, Guy _____________________________________________________________________ Guy Roberts PhD Senior Transport Network Architect DANTE Cambridge, UK +44 1223 371316 DANTE is the project co-ordinator and operator of GÉANT, the high-speed pan-European research and education network that is transforming the way researchers collaborate.

Subscription to the GLIF NSI Implementation working group
by Inder Monga 26 Nov '13

26 Nov '13

Hi All, Based on discussion at SC, it was decided that there are three best practices/agreements that are standing between NSI 2.0 specification and production NSI service. These are: 1. Security Specification for interoperability 2. Service Definition for end-to-end Ethernet service 3. Topology distribution agreement. These are sufficiently different from the NSI standards process and what needs to be standardized. So rather than clutter the NSI mailing list, we should move this discussion to the GLIF mailing list. Whoever is interested in contributing to that discussion, please subscribe: http://www.terena.org/mailinglists.php?list=nsi-imp@glif.is Also, please feel free to forward this message. Thanks! Inder Inder Monga | imonga(a)es.net Chief Technologist and Area Lead | http://www.es.net/inder Energy Sciences Network (ESnet) <http://www.es.net>
