DOCSIS config files allow one to use service flow classifiers that match on a variety of criteria. I imagine either the IP range used for public access or the SSID/VLAN/Interface of the wifi hotspot could be used in this instance. http://www.cmtsinfo.net/?howto=cm_config provides a good general overview of what's available and how to apply (see section 6 on classifiers). Of course, even if a dedicated service flow is used, this could still compete with the bandwidth available to the modem or to other modems served on the same node. I could envision this making network bandwidth management more difficult as customers roam, especially if they densely congregate. --Blake Frank Bulk wrote the following on 5/29/2014 10:27 PM:
Interesting, I may need to open a ticket with Moto to ask how that’s done.

From talking to folks involved with http://www.cablewifi.com/ and Comcast support there is a separate service flow for the public SSID. I have yet to configure that in the lab, but it sounds like a good project :)

It's my understanding that the public Wi-Fi uses the same data flow as the subcriber's data flow. I've seen nothing in the release notes for ARRIS or Moto that suggest one can tie an SSID to a specific service flow.

I expect Frank Bulk to have an opinion on this, all others welcome.
Hat tip to Bright House -- I've noticed lately that I don't have to go through their captive portal when using their public wifi hotspots (they participate in the CableWifi consortium, using WAPs built into their 6580 and other cablemodems, and offer a carrier-specific connection SSID as well).
This has led me to a point of curiosity:
If I'm the subscriber, and I've paid for 15 mb/s down, then my wired connection and my private wireless (if provisioned, and they charge $10/mo, so I'll do that myself, thanks) are using one ... DOCSIS path? back to the CMTS.
I assume that cableco provided voice is on a separate path, and I'm sure the TV service is -- if it's even IP at all.
But the question is: is that public wifi service *also* on a separate bandwidth-limited channel out of the cablemodem?
Offline replies fine, unless you think it's of sufficiently general interest; I expect it's implementation dependent.
