RE: stds-802-handoff: Achieving Reliable & Faster IP Handovers in IEEE 802.11 Network - A Relevant IETF Draft ?



Paul,
Thankyou for your input.
I will air this document at the 802 handoff meeting that is taking place
this week for consideration by the group.

Finally, I feel that the ability to embed *critical* L3 information into

L2 frames can provide some *useful hints/confirmations*, such that to 
allow mobile nodes to perform some *necessary* operation(s) before 
(after?) an upcoming L2 handoff. I hope that this draft can provide some

useful information to this group, and would also like to hear some 
comment/feedback from the group on the ID.

Thank you for your kind attention.

Cheers,
