Rate limiting per WLAN

I'm familiar with the ability to rate limit per client in ZoneDirector, but I'd like to see if I can limit the overall rate for each of our three WLANs. Can anyone suggest a best approach to do this?

Rich,

i understand what you are asking however would like to know what you plan to achieve by doing so?

We are a K-8 school, and our middle school students use Chromebooks on a dedicated WLAN. Rate limiting per client is very useful, so that no single student can tie up too much bandwidth, but I'd also like to ensure that as a group they don't use 100% of our allocated bandwidth. To be specific: we have a 50 Mbps Internet connection, and I want to limit the overall middle school (as a group, not merely as individuals) to something less than 50 - perhaps 30 Mbps.

The only way I know how to do this would be at the firewall or switch.  If your firewall supports traffic management/rate limiting, you can limit the bandwidth there.  Otherwise I think you'll have to do at the switch using rate limiting.  Don't know of anyway to do it natively on the ZD.

Right, I don't think the ZD can do this natively, and it probably isn't trivial to implement either since the ZD is an independent observer to the traffic flow at each AP. It's easy for each AP to implement a per-client rate limit, but limiting the overall per-WLAN/per-VLAN traffic would require a lot of AP to AP coordination.

This seems like it should be done either by a firewall/UTM with prioritization / rate limiting features, or a dedicated traffic equalizing appliance.
