[Nsi-wg] comments on slides

[John Vollbrecht]

These slides are very interesting.  There are a number of issues that  
this prompts that should be discussed, most of them noted in the slides.

1) handling of errors when there are failures in the middle of a  
sequence.  This will have to be handled for the error case.  If it is  
handled for that it might well be used in other cases - I think this  
should be considered.
2) the distinction between times -- what is required to set up vs what  
is needed for use seems very important.  One way to think about this  
might be the time a resource needs to be reserved vs the time the  
resource needs to be available to the user.
3) set up time is likely known only by the NRM,and then possibly only  
statistically.  A request for usable time might result in reservation  
for usable + setup.  In this case having setup initiated from a user  
several steps away means that all resources in the chain will be  
reserved at least as long as the one with the longest setuptime.


we can talk about this -- I am still thinking about it --

John
