[j-nsp] Opinions on Source Class Usage / Destination Class Usage (SCU/DCU)

[Felix Stolba]

Hi list,

Anyone able to help me out with some real world experience about Junos 
Source Class Usage (SCU) and Destination Class Usage (DCU)? We're 
considering this feature to gain a little more flexibility with our 
legacy SNMP-based traffic accounting system.

Looking for any input on the subject matter, especially:


How is it in terms of stability / interaction with other features?

How scalable is it, how hard will the performance hit be when enabling it?
Any other experience you might be willing to share?


Thanks,

Felix
