[Nsi-wg] G.805/G.800 applied to NSI

[Guy Roberts]

John,

See my comments in your G.805/G.800 document.  I think that applying G.800 to a NSI network example as you have done here is an interesting exercise.   I think the G.800 is a good model that looks well thought through and fits the NSI requirement for a vendor independent network description.

G.800 is diagrammatic oriented, as far as I understand the use of this is that it can be used as an object oriented model for creating a database that describes a network in a network management system (TMN principles).  But what we really need is a description language that will allow this network model to be exchanged over the NSI interface.  I guess the process of creating such a language is the role of the NML group.  As far as I can see ITU-T does not have anything like this for G.800 (because it is an object oriented database model only?).  Perhaps Freek can comment on this in tomorrow's call.
