Quality of Service for selected clients

Hi All,

There a couple of laptops that I would like to "hog" wireless bandwidth, from two R310s Unleashed, to prevent buffering of streamed video media content. Is this possible (or desirable)?

Many thanks in advance,
gimbers

By using the default parameters all clients will have an unlimited data rate. The only was to prefer one client over another is to rate limit the other clients. You could do this by creating a new WLAN with rate limiting for the clients that don't have the bandwidth requirements.

Thanks Mike. Found those settings and that makes sense. gimbers

Hi Rex, we deal with a lot of live streamed events. Typically I'd always use Ethernet connectivity, however if we need to use Wifi I have found it more beneficial to run access points running unleashed and broadcasting 5GHz only (If the streaming device allows 5GHz) on a separate dedicated LAN and rate limit as Mike states above, although this only rates at host level and not at network level. If you need the controllers however you can also force the Wi-Fi traffic to route via the ZD controller. We've run multi bit streams (480, 576 & 720p) on this setup and it's worked fine. Final thought is that you could also limit the volume of clients connecting to these two access points which would force hosts to connect to other access points...

Hope this helps

Wasn't heuristic QoS one of the features that SmartCast was supposed to provide at least back in the 7982 days? IIRC it automatically classified traffic into video, voice, background/best-effort queues and that way, a bulk download would probably be "background" while streaming video is "video", and it would ensure that video won't get starved out by downloads....

As far as I can tell, heuristic QoS seems to be disabled on 11ac 5Ghz radios and the commands to enable it don't seem to do anything at the CLI. On my 7982, I can see nonzero incrementing counters in "get qos ", but that doesn't seem to happen on R600/700/710.



But I think for the OP, if the bottleneck is at the WAN, it's much better to use a gateway firewall/router to perform QoS (traffic shaping, in your case), because it is the point that has full visibility, while each AP only knows about its own traffic.

Chris & John, thank you. You guys are amazing. Thanks for the input in such a clear and concise way. This is all making much more sense now...

I'm coming at this from AV, not IT, so still feeling my way.

Did a walk through of a four storey property today with two R310s, streaming HD content, and the handoff from AP to AP was seamless. Just need to add another AP on the top floor to totally nail it.

Unleashed seems to be working well.
