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.

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.
Cheers,
