[Nsi-wg] advanced reservation

[Jerry Sobieski]

Hey John -

we touched on this in the call today, but I willr espond here as well...

If the provisioning overuns the estimated GB and does not complete until 
after the requested In Service start time, then this should throw an 
error...but it does *NOT* automatically mean the request or the 
conenction should be rejected and torn down.   IMO, if the user doesn't 
want it anymore, they should send a Cancel msg down the tree.   IF its 
ok despite the overrun, they can ignore the Error.  

Its not clear to me if the conenction should remain in an errored state 
after notification.  Or if the user must reply to the notification 
somehow.   This is something maybe Inder can elaborate on in his error doc.
