stds-802-handoff: Achieving Reliable & Faster IP Handovers in IEEE 802.11 Network - ARelevant IETF Draft ?
I am currently working in the area of fast handoff management in 802.11
networks, and would like to learn more from this group.
I have earlier submitted an individual Internet Draft (ID) to the IETF
regarding the above problem.
Basically, the ID proposed a way to achieve faster movement detection
(MD) when a mobile node moves across several APs which are connected to
different networks/providers. It also provides some useful neighborhood
discovery (ND) mechanism such that mobile nodes can handoff to their
*choice* of networks, based on the *advertised* information of each
network. These operation (MD & ND) are critical to achieve *seamless* or
*loss-less* IP handover. The proposal leverage on the underlying 802.11
control frames such as Beacon frames to carry *Extensible Information
Elements*. You can read the ID for more details at
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.
