Dear Jag, Rakesh, and Xiao Min,
I feel confused. The way I understood the pool's question is whether the
group supports standardizing a single solution document or whether each of
proposed solutions can be standardized (WG Chairs, please correct me if I
misunderstood your question). From your previous emails, it appears that
you support the latter - possibly standardizing multiple data plane
solutions. Could you please clarify. Also, I don't find in the poll
question about which of the solutions, already proposed or to be proposed
soon, to be standardized. It seems like being disciplined and following the
scope of the questions will help us progress this work faster.

Regards,
Greg
