We deployed Xfinity on Campus last summer for 6,000 residents. Our Comcast estimate was max 3 - 5 Gbps additional internet load so we upgraded firewalls to accommodate. Turns out between IPTV and natural growth it was only ~ 1 Gbps more than the prior semester. Almost all of them stream over wireless and we have not adjusted the data rates. Everything is performing well (of course we have one AP per suite so coverage is very good).

I am looking at it from the wireless perspective.... And my boss is worried :) Our platform is all Cisco. 8540 controllers (8.3) and a mix of 3502, 3602, 3702, and 3802 WAPs. Our transmit rates are: 802.11 a [cid:image001.png@01D2BF77.B58918C0] 802.11 b/g [cid:image002.png@01D2BF77.B58918C0] Specs show IPTV needs 2Mbps to stream 720p content to client devices. >From the wireless perspective, have you (or anyone else on this thread),had >any problems with IPTV? Did you have to adjust your data rates since multicast travels at the lowest mandatory?

What is your wireless platform? We implemented multicast IPTV on Aruba wireless using our existing Haivision wired IPTV services. In fact, we helped Aruba test their "Dynamic Multicast Optimization" solution. Generally, for 802.11 networks, multicast is transmitted at the lowest transmitted rate. That is bad for multicast video. Since our video streams are encrypted, we cannot apply QoS separately to prioritize key frames. If you wish, I can reach out to our IPTV team to get more information on our Haivision (formerly Video Furnace) system.
