[Nsi-wg] NSI WSDL - The Maastricht Updates

[Jerry Sobieski]

Hi Henrik-

I want to point out the the "bandwdith" is actually a service specific 
parameter, where as the other two aspects (schedule and path) are 
generic and apply to the general semantic of a "connection"  regardless 
of service definition.     Different services may have different ways to 
define the connection capacity...bandwidth, timeslots, spectral width, 
etc.   Even two similar services may define their service capacity 
differently - say an implicit constant bit rate, or a committed 
information rate with burst capabilities, etc.  I suppose we could 
consider the "size of the pipe" as a generic characteristic - it has an 
applicable elegance to it, but we would then need to reconcile these 
different ways of defining the size that might vary by service specifics...

So the group should just keep this in mind - we can define an expedient 
solution for v2 as you suggest (I think a 80% solution that moves v2 
along is most important at the moment ), but we should revisit this 
issue in v3.
