Notes for NML call 23 February ============================== Attendance: Aaron Brown (I2), Freek Dijkstra (SARA), Jeroen van der Ham (UvA), Jerry Sobieski (Nordunet) Excused: Jason Zurawski, Chin Guok 1. Action items from previous call: ---------------------------------- * Jeroen to go through document and set up action points * Jeroen to check the Security considerations of NM * Freek to write use case on bidirectional and unidirectional links: single fiber with two wavelengths in different directions. * Jerry to write use case on bidirectional and unidirectional links * Jerry to write usecase on NORDUnet being a geographical segregated network (NY and CPH), with possible restrictions between the two locations/networks * Jerry to write this down federated and sub-NSA as a use case. * Freek and Jerry look at the exact definition of NML:Topology and NSI Network, and see if they can sync their definition 2. Current schema document status --------------------------------- Jeroen has gone through the document and distilled some new action points: - Introduction needs some updating and extension - Schema figure must be moved to front and checked against current definitions (Jeroen) - "at layer" relation must be examined, there currently is no Layer object. (Freek) - Identifiers section needs to be fixed, and needs its own introduction (Jeroen) - Examples is work in progress - Security considerations: The ones from NM are pretty short and basically say that descriptions may be sensitive. Implementers should be careful with distribution. We don't want to add much more than that. 3. Other action Items --------------------- - Freek and Jeroen will prepare a presentation for the NSI session at OGF34 - Freek's use case action still stands - Freek will contact Jason about possibly switching NMC and NML calls. 4. Discussion on aliases ------------------------ We had a short discussion on whether NSI descriptions and physical topology descriptions are different things. One is something like a service, the other is the actual instantiation of it. This is similar to identifiers for books, stories, translations and physical books. Freek remembers that libraries have a solution for identifiers on those things, he will try to get a link to that and post it. Jerry and Freek will discuss his slides, we can then discuss them in the next call on March 8th.
