If you’re the customer of a major American internet provider, you might have been noticing it’s not very reliable lately. If so, there’s a pretty good chance that a graph like this is the reason:
These graphs comes from Level 3, one of the world’s largest providers of “transit,” or long-distance internet connectivity. The graph on the left shows the level of congestion between Level 3 and a large American ISP in the Dallas area. In the middle of the night, the connection is less than half-full and everything works fine. But during peak hours, the connection is saturated. That produces the graph on the right, which shows the packet loss rate. When the loss rate is high, thousands of Dallas-area consumers are having difficulty using bandwidth-heavy applications like Netflix, Skype, or YouTube (though to be clear, Level 3 doesn’t say what specific kind of traffic was being carried over this link).
This isn’t how these graphs are supposed to look. Level 3 swaps traffic with 51 other large networks, known as peers. For 45 of those networks, the utilization graph looks more like this:
The graph on the left shows that there is enough capacity to handle demand even during peak hours. As a result, you get the graph at the right, which shows no problems with dropped packets.
So what’s going on? Level 3 says the six bandwidth providers with congested links are all “large Broadband consumer networks with a dominant or exclusive market share in their local market.” One of them is in Europe, and the other five are in the United States.
Level 3 says its links to these customers suffer from “congestion that is permanent, has been in place for well over a year and where our peer refuses to augment capacity. They are deliberately harming the service they deliver to their paying customers. They are not allowing us to fulfill the requests their customers make for content.”
The basic problem is those six broadband providers want Level 3 to pay them to deliver traffic. Level 3 believes that’s unreasonable. After all, the ISPs’ own customers have already paid these ISPs to deliver the traffic to them. And the long-standing norm on the internet is that endpoint ISPs pay intermediaries, not the other way around. Level 3 notes that “in countries or markets where consumers have multiple broadband choices (like the UK) there are no congested peers.” In short, broadband providers that face serious competition don’t engage in this kind of brinksmanship.
Unfortunately, most parts of the US suffer from a severe lack of broadband competition. And the leading ISPs in some of these markets appear to view network congestion not as a technical problem to be solved so much as an opportunity to gain leverage in negotiations with other networks.
Netflix has been forced to cut private deals with ISPs. Is that undermining net neutrality?
In February, Netflix agreed to pay Comcast to ensure that its videos would play smoothly for Comcast customers. The company signed a similar deal with Verizon in April. Netflix signed these deals because its customers had been experiencing declining speeds for several months beforehand. Netflix realized it would be at a competitive disadvantage if it didn’t pay for speedier service. After its payment to Comcast, Netflix’s customers experienced a 67 percent improvement in their average connection speed.
Netflix has accused Comcast of deliberately provoking the crisis by refusing to upgrade its network to accommodate Netflix traffic, leaving Netflix with little choice but to pay a “toll.” That might sound like a classic network neutrality violation. But surprisingly, leading network neutrality proposals wouldn’t affect this kind of agreement at all.
That’s because Comcast wasn’t technically offering Netflix a “fast lane” on an existing connection. Instead, Netflix paid Comcast to accept a whole new connection. The terms of these agreements, known as “peering,” have always been negotiated in an unregulated market, and network neutrality regulations don’t apply to them.
In theory, Netflix’s deal with Comcast doesn’t violate network neutrality because everyone on this new pipe (e.g. only Netflix) is treated the same, just as everyone on the old, overloaded pipe gets equal treatment. But it’s hard to see any practical difference between the kind of “fast lane” agreement network neutrality supporters have campaigned against and Netflix paying Comcast for a faster connection.
So why hasn’t interconnection been a bigger part of the network neutrality debate? Until recently, it was unheard of for a residential broadband provider like Comcast to demand payment to deliver traffic to its own customers. Traditionally, residential broadband companies would accept traffic from the largest global “backbone” networks such as Level 3 for free. So anyone could reach Comcast customers by routing their traffic through a third network. That limited Comcast’s leverage.
But recently, the negotiating position of backbone providers has weakened while the position of the largest residential ISPs — especially Comcast, Verizon, and AT&T — has gotten stronger. As a consequence, the network neutrality debate will be increasingly linked to the debate over interconnection. Refusing to upgrade a slow link to a company is functionally equivalent to configuring an Internet router to put the company’s packets in a virtual slow lane. Regulations that try to protect net neutrality without regulating the terms of interconnection are going to be increasingly ineffective.
I remember 15 years ago or so, the liberals were whining and crying because there was too much investment in supply and that there was too much dark fiber. My reply was that there wasn’t enough investment in services to use the dark fiber.
As one of the civil engineers on the internet superhighway, I can tell you that the nice thing about standards is that you have so many to chose from. The real problem is in how the Telcos and ISPs cost model their business.
Telcos and ISPs have approached the internet from the phone business model where there is a connection and the end user can connect to anywhere else. So that is how they sell access. Comcast will charge you for different levels of internet speed. This model presupposes that all internet traffic is the same and has the same characteristics. However, that is not the case.
I am of the opinion that the first Telco / ISP that figures out how to sell tiers of service to the general public, will make a killing.
is somebodies email not getting delivered?
send it twice.
Same happened to me with my AT&T connection.
Watching a movie on Netflix that kept stalling and
restarting. I gave up!
Can you expand on that a little? What did Overland Park do to jerk Google around?
And you can't see it without a sarcasm tag?
Then fight that BEFORE giving the monopolies ever MORE power. You have this fight completely backwards.
It seems that after negotiations with Google, Google was ready to move ahead with installing Fiber in OP, but at the last minute the OP City Council decided to delay the vote, telling Google, "we'll get back to you." Google was not amused.

Idiots.
Two adjacent suburban cities here are getting it. I figure we’ll be in the first round of expansions beyond those.
But without internet monopolies what can the media base it’s calls for more internet regulation on?
Gee, think of the media’s profits...
