Hi!

Imagine power outage in one of the server rooms with WLCs - it causes all the APs to failover to another WLC until power is back.

For someone with improper network design, a single port on the switch, going to the WLC, can cause WLC's outage, again with APs failover to other WLC.

SW upgrade on the WLC can kick the WLC out of service too.

And all this situations can last from 30 min to several days or even weeks :) So, there's enough motivation for AP movement between WLCs, not everyone can buy clusterable WLCs :)

I have some ideas of how this stuff can be implemented.

Jesus. What is the motivation behind APs moving between controllers? oO

Enterprise loves needless complexity. Gah.

That is a pretty important point for Junpier. The APs move around all
along. Persistent graphs would be a great start but in the end only
something like a "virtual device" as an umbrella over all WLCs and APs
might make sense or in our case "make it useful". I think of something
like a device "Wireless-Cluster-1" which looks like each single
WLC but shows all the APs which belong to the same wireless cluster.
i.e. the sum of all APs of all cluster members.

Just as a wish/ dream :-).
