Attendees: Sheng Jiang, Xin Sun, Rana Sircar, Vladimir Marbukh, Michael Behringer (notes)

Subject: Evolving the NCRG framework draft

Brief notes: 
-	Suggestion to include metrics and tradeoffs in the framework draft; this was presented in Paris. 
-	draft-retana suggest more metrics, and trade-offs, these should also be in the framework draft. 
-	Sheng: Does cost (for example) represent a good metric? 
-	Cover the aspect of complexity: user facing? Internal, eg s/w complexity? 
-	Include text to describe the various forms (?) of complexity
	+ Operational complexity
	   deployment complexity; configuration complexity, trouble shooting
	+ Network system complexity
	  s/w complexity; h/w complexity; Protocol / algortihm complexity
	+ Management system complexity
	  OSS systems, etc.
-	Intrinsic complexity of the system vs complexity from the user base?
-	Rana: Should we limit to layer 3 and above? Or cover optical, wireless, etc? We may want to explain in the scope that the doc doesn't want to be specific to a particular solution/layer. 
-	Rana: Cost is a very good metric to measure complexity. 
-	Xin: Could improve 3.2: define different types of complexity. (operational complexity, s/w complexity, 
-	Vladimir: participated in a Santa Fe Complex Systems Institute workshop on network complexity; will point us to it. Also a recent Nature article. He could present to the group about these findings in Berlin. 

Next steps: 
-	propose on the list what you would like to contribute to the draft, or how it should be changed. 
-	set up bi-weekly calls to make progress on this. 

Thanks all for the discussion!
