Note: It is definitely not built under that premise, hence why your consumer bandwidth is asymmetrical...

The Tier 1 always wants to ask for more bits than a lower tier operator. If a lower tier operator asks for more bits and tilts the traffic balance, things get interesting. Cogent is not a tier 1 but slings 35% of the internet around at will.

It does cost a lot of money to route Netflix's bits and the narrative is hugely helpful to Netflix. I'm not saying this is correct, I'm simply trying to point out that Netflix has a ton to gain from carriers upgrading their network connections and routers.

Another way to view this: Netflix is demanding huge network upgrades without any additional revenue source.

Netflix is demanding huge network upgrades without any additional revenue source.

I think a lot of us would have more sympathy with the ISPs' situation if they hadn't consistently and for a very long time been promoting their services as ever more valuable by offering ever higher bandwidth, yet keeping quiet about little things like massive over-subscription and high contention ratios that meant if all their users actually tried to use the service that was purportedly being offered then no-one would get anywhere near the advertised speeds they were paying for.

With the rise of things like streaming video services and Internet telephony, some people are actually trying to pull significant volumes of data down the pipes relative to the advertised size of pipe available. Everyone's known this was coming for a long time, and no-one more so than the ISPs. The way I see it, if the current situation hurts ISPs that failed to invest or set a realistic pricing model, they'll just have to take their medicine and offer a more realistic deal to customers next time (or fail because they can't compete effectively).

If Netflix closed its doors today, presumably Amazon Prime and Hulu would pick up the slack. The problem is not Netflix providing content; the problem is users consuming it. Users want better service than the ISPs are inclined to provide.

Sounds to me like just another way of rephrasing "ISP Customers are demanding huge network upgrades without any additional revenue source."

Netflix does not send packets to you unless you request them.

silverstorm didn't say anything about symmetrical. If Comcast assumes that the various interconnect points are relatively even in traffic usage, but then the few that go to Netflix start getting congested (leaving the rest relatively light), they're going to have to upgrade just a few spots with really expensive equipment just to deal with Netflix traffic.

Edit: not sure why I'm getting downvotes since silverstorm clarified exactly what I wrote

I am not talking about imbalance in U/D, but rather imbalance in destination (or source). If tremendous amounts of traffic is going to or from just a small handful of nodes, you need tremendous routers & pipes going to those nodes.

> they're going to have to upgrade just a few spots with really expensive equipment just to deal with Netflix traffic

You're missing a key element of the situation: Comcast made a deal with Netflix precisely to address this problem. Netflix now has direct connections to Comcast's network, so Netflix traffic does not have to go through a third party. In other words, Comcast now directly controls how they connect to Netflix, how many connection points there are, what the average network distance is between the closest Netflix connection point and their customers, etc. So they have a much cheaper way to even out Netflix traffic: open up more connection points.

(Which, btw, AFAIK they already did as part of the deal; they certainly did not come out of the deal having "just a few spots" where they are connected to Netflix. Netflix basically is their own CDN; they have servers with their content on them all over the Internet. So Comcast has all kinds of ways to shorten the average network distance between each of their customers and the closest Netflix endpoint.)
