AVC or Advanced QoS on the 5760 platform

[R2C CCIE/CWNE]

This is more of a question about QoS where my knowledge is still limited. Which is why I am looking for some pointers to what the benefits of the advanced QoS on the 5760 have over AVC? Performance and UWN architecture of the 5760 set aside AVC can mark a application specific packet with a DSCP value which can be trusted from the wlc LAG ports. Afterwards you can apply policing and shaping as well.

If AVC profile mapped to WLAN has a rule for MARK action, that application will get precedence as per QOS profile configured in AVC rule overriding the QOS profile configured on WLAN.

In the current IOS-XE 3.3.2 version it is only Application Visibility & NO CONTROL. In CA, this AVC feature happening at the AP level & due to this only 2600/2700,3600,3700 AP supporting this feature. See below post for some configuration detail of AVC in 5760.

In fact 5760 designed for MC in a large scale deployment where 3850/3650 (MA) terminating all capwap traffic. So you can apply same wired QoS policy to your wireless. This post should give some indication on this.
