[netext] 回复 :RE: Consensus call to adopt I-D:draft-korhonen-netext-redirect as WG doc

Hi

Sure, I know your question. In my mind, we can use this mid-session redirection associated with bulk-re-registration. 
Therefore, the LMA can perform redirection per MAG. In such case, the operation time will be short. 
In addtion, LMA can notify MAG the maintenance operation by out-of-band means. 

The path failure is another scenario describe how to redirect mobility sessions.

Maybe somebody has different thought on mid-session redireciton scenario.
