Comcast response to Netflix

* Netflix cannot make money if individual Internet users cannot connect to Netflix and stream their movies. Netflix brings in a lot of revenue from its customers, and even after the cost of its own Internet connection manages to turn a handsome profit.

* ISPs stand between Netflix and their users. Many ISPs, such as Comcast, are also involved in the business of selling subscriptions to TV channels (usually with plans that require people to pay for hundreds of channels they do not watch) -- a business that is dying because of Internet streaming. Since Netflix relies on ISPs to have customers at all, ISPs want to demand money from Netflix (as well as from their customers).

* Somewhere in there are the actual users of Netflix, who have no particular say in any of this. Most of those users would have been happier with BitTorrent, but are too terrified of lawsuits (and even if they did turn to torrents, certain ISPs -- i.e. Comcast -- have been known to deliberately interfere with their customers' traffic to thwart torrents).

If your reading of this is, "ISPs are greedy and want to double-dip," well, yeah, that's what is happening here.

Most large ISPs won't freely peer with Netflix though; that's actually an industry standard, because peering is usually regulated by some kind of traffic balance between packets entering and exiting the network; e.g.: network A will peer with network B is they both exchange similar amounts of traffic in both directions. In Netflix case, it's obvious that this is impossible.

In those cases, Netflix would rely on paying the transit service; that is, they pay Cogent to bring their traffic into Comcast, because Comcast and Cogent already have some (secret) agreement in place (either feee or paid peer, who knows); Netflix would be happy to just pay Cogent to reach Comcast users. They would call it "a compromise" because their best option would be to freely peer with Comcast, but again, it's been an industry standard forever that peering is not only a factor of physical connection, but also of commercial power and quantity of packets sent and received (who needs to send more is the one that has to pay).

Netflix is now saying that Comcast is deliberately letting their peering with Cogent saturate and refusing to upgrade it (or offering economic conditions that Cogent won't accept, which is the same). This way, Netflix must enter a direct (paid) peering agreement with Comcast, to be able to offer good quality to Comcast users; in that agreement, Comcast will let Netflix pay whatever they see fit to reach their users. The peering here would obviously be paid and not free, since (again) there is a strong disproportion between packets going in/out the network.

google has similar issues with some EU providers in particular in france, for youtube.

traditionally the ISP pays to upgrade the pipes for the content that is provided by a third party (ie ISP pays for youtube, netflix traffic). ie the one whos downloading pays for upgrading pipes.

thats where some ISPs (comcast too then i guess?) generally cringe: this way of dividing costs was ok 10 years ago, but not anymore: streaming is 90% of their traffic and its not sustainable.
