RE: Betr.: Re: [WIRELESS-LAN] You knew it was coming...Airplay/Apple TV support for instructors.
We have a solution we are using for our football stadium televisions, but the PoE boxes can sometimes become unresponsive and need the port bounced. They are the PoE version of the Enseo HD2000 LP, I believe. http://www.enseo.com/images/products/ProductPDFs/hd2000lp_v2.1.pdf If you want more information, contact ne off-list and I can connect you with our people who work with these devices.

So it's not just about the bandwidth. B'cast M'cast use the lowest configured data rate of the AP - just like wireless management frames. This means that even for 300Mbps 802.11n network is reduced to 24Mbps or less. That also ties up airtime that could be given to faster clients as well, since transmitting data at a lower data rate consumes more time that transmitting data at a higher data rate. So even if it is a low bit-rate stream, it takes away more available bandwidth from other clients. Aruba has a method that takes b'cast m'cast and converts it to higher speed unicast traffic to each client. This gives better results for about up to 12 clients

Has anyone actually tracked how much bandwidth/usage Bonjour coughs up across their wlan infrastructure? I haven't analyzed it, and while it could be bandwidth hungry, it appears to me
