After doing some more research about EDCF and WMM (QOS things to improve voice over wireless), i am trying to set this up for the multicast streaming.
However, in the Unified Wireless Multicast Design guide, i see "The QOS bits of the LWAPP multicast packet are hard coded at the lowest level and are not user changeable". And indeed, i have done a sniffer capture of a multicast stream: it enters the controller with DSCP EF, however the LWAPP encapsulated packets to the LWAPP distribution group have DSCP 0.
According to the QOS Voice design guide, the DSCP marking of the original packet is transferred into LWAPP packet and from their on the 802.11.
Does this mean that the whole EDCF and WMM stuff to improve QOS on wireless, doesn't effect the multicast stream ? So with real multicast, i am stuck with QOS = 0 ??
