[Nsi-wg] revised slides/ call notes

[John Vollbrecht]

At our call today were Guy, Chin, Tomohiro, Jerry, Joan, Inder and my  
self.

1) we discussed the model of what we are now calling a NS Actor/ 
Component.   We defined the components of this as

NSI -- Network Service Interface
Provider agent - provider side of NSI
Requestor agent - requestor side of NSI

NS Actor - set of actors that perform act as a whole.  Includes one or  
more NS agents/ 0 or 1 provider agents, 0 to N requestor agents
Actor may be renamed Component -- to be discussed in future

We agreed on these names based on Joan's description of web services  
definitions.  Joan will provide a writeup and pointer(s) to this for  
the doc.

Attached is a modified ppt that includes these names as I understand  
them.  This is based on a version I got from Joan and modified a bit  
more.  Comments and corrections please.

2) we discussed in the PPTs I sent the role of aggregation/ 
coordination module.  This requests resources from other agents and  
returns them with appropriate parameters to the requestor.     The  
resource returned by the Provider agent includes all the resources  
aggregated by the aggregation/coordination module.

3) we discussed the diagram that Chin sent out with functional  
modules.  There was a lot of discussion about this, and Chin suggested  
that we focus in the short term on defining elements and put the  
diagram on hold till we get farther on this.   People liked the  
concept of the document and that it helped discussion, but now needs  
to be revised.  Every one should send comments to Chin on this.

-- some comments I remember:
a) Part of Authentication and authorization may need to be part of NSI  
interface.  Other parts may be in RMM agent and in Actor support  
modules.
b) aggregation/ coordination module should be added to the diagram
c) message interpretation/ analysis should probably be included  
somewhere -  the concept that there might be simple/ loose/ strict  
requests.

There will be a protocol meeting at SC at 2PM PT Tuesday next week.   
The next regular call will be Wed Nov 25 at 9ET.
