Similar confusion by wisely avoidance -:)

If possible, Someone can draw a simple picture of IRS location in a router with existence of other components.

Also, I think people are confused by the comparison with SDN and OF. More clarification will be helpful.

Tom,

It is confusing to understand whether IRS belongs to a new network management plane or if it's more of a control plane extension. The draft wisely avoids this classification.
To me IRS appears to be a completely different beast which should best be  characterized as 'Network Programming Plane' NPP. 
It neither aims to do full provisioning (as a management plane would do) nor aims to replace routing (as a control plane would do).
Hence we better name the baby NPP -- thereby avoiding any linkage to taxation.


Gert
