What is the difference in who will be responsible for "split plane"?
It is obvious that:
- decreases the traffic of the data core switches;
- WLAN capacity increases in direct proportion to the number of access points.
Sorry I neglected to respond
When it comes to apply policies to WLAN Traffic, we are now asking the Access Point to apply policies, limit users and other security measures. In a centralized WLAN infrastructure these were done by the Wireless Controller. These types of task can be done on a regular basis at a higher speed by L2/L3 Switches. I would think a L2/L3 switch would be better equipped to handle this extra load.
Another factor is Roaming of mobile devices, in a Centralized WLAN infrastructure that was not much of a problem, but when Access Points now have to handle what the Controller used to handle, and now we want the AP to handle Roaming tunnels to ensure minimal wireless disruption. If you are running VoWLAN this becomes important.
When you start to increase the requirements inside the Access Points that could drive price of the device up as well.
Just one question which is better prepared to handle more task? The AP or L2/L3 Switch?
