Re: Comcast Xfinity for Xbox launching soon (possibly next week)

said by tshirt:

They could be selling this over differnt IP channels than either resi. or Biz HSI uses, not so different than voice using private/non-public channels

I didn't think so - doesn't the XBox just get connected to your home network, just like any other IP device you might have?

yes, exactly.

OK, so how does Comcast discriminate between the XBox bits and your other IP device bits, so as not to count the XBox ones against the 250GB/mo cap?

Do they meter the capacity used from the "XBox VoD app" server and just subtract that figure from your total HSI data usage?

Because it's hitting designated Comcast internal IPs, which they will whitelist in the cap (i.e. not count).

Jeff Baumgartner on the Light Reading Cable site had this comment on the issue:

From: Comcast's Xbox App Raises Net Neutrality Concerns
Light Reading Cable - March 27, 2012
»www.lightreading.com/document.as···r_cable&

"So, at what point do these groups start pointing the finger at any SP that delivers video over a managed IP network and doesn't apply those services toward any sort of data cap? Might as well toss AT&T into that group, along with a bunch of other telcos that are offering managed IPTV services. Though they'd be wrong to do so.

The other interesting aspect here is that MSOs like Comcast will have to embrace IP video if they are to get their services, including linear TV, onto more CE platforms like Roku and the Xbox 360, PS3 and Wii, not to mention connected TVs. So if managed IP video is the vehicle to get cable services available on more retail devices without an MSO-supplied set-top, it seems a tad ironic that PK and Free Press are trying to lump net neutrality into this when they have been among those pushing for cable to do a better job at supporting services on retail CE devices.

If Comcast reversed course and said it was going to start applying data from managed IP video toward a cap, I think there would be an absolute uproar. After the P2P fiasco from awhile back, I would think Free Press and PK would give Comcast some credit here for being transparent about its policy for Xfinity TV on the Xbox 360, though I am certainly interested in hearing more about how Comcast is going about it, technically speaking.

But I'll admit that this will cause some confusion for customers, who are now supposed to figure out which apps on the Xbox 360 count against a usage cap (ie. Netflix) and which ones don't. I doubt that the average consumer knows the difference between OTT and managed IP video, or would even care to know."

So, the question is - at what point is the problem where frequent Netflix users "cause congestion and impact internet performance for [Comcast's] other customers" requiring the imposition of a monthly data cap?

Is it somewhere inside the local HFC plant, or where Comcast interfaces to the public internet?

It is where the CDN dumps the Netflix traffic onto the comcast network. Like I said, easy to explain to anyone who knows how networks work.

Couldn't the xbox request program 12983 be sent specific IP and port, while this is via IP I don't think CC(or any other ISP) has ever said ALL their available IP bandwidth will be dedicated to HSI delivery.
The network neutrality "pledge"* only applies to the 250GB's included in your residential package with various prices based on the speed you want to use it.

You might have a better case if you are a biz HSI and TV user where your HSI doesn't currently have a cap (keep pushing, they'll change that) and the ToS is different (not sure biz TV includes ON demand products)

CC and the rest of the industry spent a lot increasing total capacity via D3 upgrades (and other emerging tech), and they don't intend to just give it away.
They will continue to find other services (voice, home security, etc) to pay back and even profit from that investment, and many of them will be via the "private IP space".

OK, so if that is truly where Comcast's HSI data bandwidth bottleneck is, then yes, Netflix video streaming IP traffic could be a problem, while internally-sourced Comcast VoD IP traffic would be fine.

In that case, applying the 250GB/mo cap to only the non-Comcast-originated VoD IP content would make sense.

It was my understanding (I am not sure, so take it for what its worth) that xfinity xbox app/service was only available for residential vid + res HSI customers.
