This appears to mix different kinds of state.
In particular, with regard to state in network resident boxes, there can be:
General state covering all subscribers;
Per subscriber state provisioned state;
Per subscriber dynamic, but not flow specific state;
per flow state.
All are state.
The first is clearly permitted.
The fourth is clearly not permitted in a "stateless" solution.
Some descriptions of "stateless" have allowed for the middle two, while
others have prohibited it. I have no opinion on what the WG "agreement"
is on the scoping. But we need to be careful about what we mean about
"state".
Yours,
Joel

Hi Satoru,
In MAP 1:1 mode, if there are 10000000 subscribers, there would be
10000000 MAP domains which a BR has to manage. I think that will create
a huge mapping table on the BR, which is called 'state' that stateful
solutions deal with.
Best Regards!
