On the call were Jeroen, Tomohiro, Joan, Chin, Freek, Guy, Gigi and myself. Discussion 1. Joan describe work he is doing with describing NS agent interfaces. He is working on slide set and will hopefully be able to present it next week or the week after. Some discussion - discussed the difference between dataplane which can be modeled by G.800 and the control plane. Tomohiro said that we should have a third plane that describes coordination between NS agents differently than coordination of dataplane [I may have this wrong - Tomohiro might want to comment}. - Chin talked about architecture document being worked on for DOE that describes a service plane, and as I understand it the service plane describes all interactions with NS agents. Interactions between agents is (I think) always with web services. Chin will see if it is possible to share this doc with the NSI wg. - there was some discussion of how Lookup Service and Path Computation capabilities fit into this. These seem like Information service similar to DNS or BGP for IP. - This is a subject to be discussed further in the group - by email and on calls. 2. Guy is working on a context section for document and will have a draft for next week 3. We discussed G.800 and NML and NSI. Consensus was that G.800 was a good way to describe NSI type networks. Concepts of G.800 map nicely to NSI concepts. Guy suggests that we consider using G.800 naming for NSI. I am not sure that works completely, but would be good if it could. One issue is that G. 800 concept of subnetwork is NSI concept of network. There may be other issues. We should consider this. We discussed how G.800 and NML interact. Seems that G.800 describes concepts that are included in NML schema. This is mostly done, NML group is working on details of schema now. Once schema is done then it is represented in a language. Discussed the difference between NML and GMPLS description of adaptations. My take is that GMPLS defines specific adaptations in detail, while NML wants to have abstract adaptations with capabilities assigned to each instance. Gigi raised the question of whether G.800 had been implemented by any vendors or providers. Jeroen agreed to ask the same question on Friday on the NML call. I am wondering the same for GMPLS. - We will have a call next week - Wed at 9ET. please add, correct or comment on notes - John
