Scott, et al,

Your draft listed comprehensive requirement on what data you need to pull out 
of a router.

The Section 3 (Use Cases) , I was hoping to see some use cases on how those 
collected data are used. But Section 3 only listed bunch of data that you need. 
So Section 3 is really the "Requirement" (instead of use cases).

Do you have any examples showing how those data are used? Concrete examples can 
greatly help router vendors to prioritize the information to be pulled when 
there is resource contention. Even though the primary objective is  "Collecting 
large data sets with high frequency with minimal impact to device's CPU",  very 
often "large set & high frequency" do need CPU cycles.

Both Syslog and IPFIX were intended to export data from devices. What are the 
limitation of those schemes?

Thanks, Linda Dunbar
