Tubes Offers an Internet Tour

If you have been trying to find a book that offers an engaging explanation of how the Internet physically works and the various networks interconnect, search no more. Tubes: A Journey to the Center of the Internet by Andrew Blum has done it.

The author was featured on Fresh Air way back in May, but not much has changed with Internet infrastructure since then.

In Tubes, journalist Andrew Blum goes on a journey inside the Internet's physical infrastructure to uncover the buildings and compounds where our data is stored and transmitted. Along the way, he documents the spaces where the Internet first started, and the people who've been working to make the Web what it is today.

He was also just on C-Span's "The Communicators."

I enjoyed the read and learned a few things along the way. Those looking for a dry, just-the-facts-ma'am approach may not enjoy the frequent musings of Blum on his experiences. But I did.

One of his trips took him to a community in Oregon called The Dalles, where a municipal network allowed Google to build its very first "built-from-scratch data center." More on that in a post to come soon...

Those who are doing their reading on tablets now will be interested to know that the eBook is temporarily priced at $1.99. The deal lasts until New Years according to the author.

Why Wi-Fi Performance Varies Greatly

Why can Wi-Fi be so great in some places but so awful in others? (Ahem... Hotels.) Time to stop imagining Wi-Fi as magic and instead think of it just as a means of taking one connection and sharing it among many people without wires.

If you take a ho-hum connection and share it with 10 people, it becomes a bad connection. On the other hand, if you take a great connection and share it with those same 10 people, they will be very happy surfers. As Benoit Felten recently told us, the best wireless networks have been built in cities with the best wired infrastructure.

Wi-Fi still has hiccups but they are well worth it for convenience, mobility, and ubiquity. In a recent GigaOm article, Stacey Higgenbotham detailed additional reasons that not all Wi-fi is created equal.

Higgenbotham lays out the limitations of Wi-fi and breaks down the technology's touchiness into four main factors. She addresses the issue specifically for travelers. From the article:

Backhaul: For most Wi-Fi is their access to the internet, but it’s actually just a radio technology that moves information over the air.

Density:…the more people you add to a network — even if those people are just checking their Facebook page — the worse the network will perform.

Movement: Wi-Fi connectivity is designed for fixed access, meaning the radios stay put...when you try to jump from hot spot to hot spot problems occur.
...
Device: Newer phones and tablets are supporting a dual-mode Wi-Fi radio, which means they can hop from the 2.4 Ghz band to the 5 GHz band….now with phones like the latest iPhone that have dual-band support, you may hop to another band only to find a bunch of other users.

Higgenbotham doesn't have the answers on how to improve service, but she offers practical advice:

Given these constraints, it hopefully makes a little more sense when you can’t download a movie while on Amtrak or your Facebook video keeps buffering as you surf on the jetway. Unfortunately, with so many variables, there’s not a lot that the Wi-Fi Alliance or even the hot spot provider can always do. If there’s a business case for faster backhaul and a better managed network, the provider will make it happen. But in places like a doctor’s office or free hotel Wi-Fi where that economic incentive isn’t always clear, they may not. And for crowded planes and trains, the solution may just be for users to grin and bear it.

There you go, it isn't magic. But we can do much, much, better if we recognize the incredible value of being able to connect anywhere with devices of our choosing is worth much more to us than it is to cable and telcos who only about the maximum we are willing to pay to live in that world.

This is an infrastructure and the communities that can ensure residents and businesses have access to the networks they need at affordable prices will thrive.

How Chattanooga, Bristol, and Lafayette Built the Best Broadband in America

We are thrilled to finally unveil our latest white paper: Broadband At the Speed of Light: How Three Communities Built Next-Generation Networks. This report was a joint effort of the Institute for Local Self-Reliance and the Benton Foundation.

We have chronicled how Bristol's BVU Authority, Chattanooga's EPB, and Lafayette's LUS built some of the most impressive broadband networks in the nation. The paper presents three case studies and then draws lessons from their common experiences to offer advice to other communities. Here is the press release:

The fastest networks in the nation are built by local governments, a new report by the Institute for Local Self-Reliance and Benton Foundation reveals

Chattanooga, Tennessee, is well known for being the first community with citywide access to a “gig,” or the fastest residential connections to the Internet available nationally. Less known are Bristol, Virginia, and Lafayette, Louisiana – both of which now also offer a gigabit throughout the community.

A new report just released by the Institute for Local Self-Reliance (ILSR) and the Benton Foundation explains how these communities have built some of the best broadband networks in the nation. Broadband At the Speed of Light: How Three Communities Built Next-Generation Networks is available here.

“It may surprise people that these cities in Virginia, Tennessee, and Louisiana have faster and lower cost access to the Internet than anyone in San Francisco, Seattle, or any other major city,” says Christopher Mitchell, Director of ILSR’s Telecommunications as Commons Initiative. “These publicly owned networks have each created hundreds of jobs and saved millions of dollars.”

“Communities need 21st century telecommunications infrastructure to compete in the global economy,” said Charles Benton, Chairman & CEO of the Benton Foundation. “Hopefully, this report will resonate with local government officials across the country.”

Mitchell is a national expert on community broadband networks and was recently named a “Top 25 Doer, Dreamer, and Driver” by Government Technology. He also regularly authors articles at MuniNetworks.org.

The new report offers in-depth case studies of BVU Authority’s OptiNet in Bristol, Virginia; EPB Fiber in Chattanooga, Tennessee; and LUS Fiber in Lafayette, Louisiana. Each network was built and is operated by a public power utility.

Mitchell believes these networks are all the more important given the slow pace of investment from major carriers. According to Mitchell, “As AT&T and Verizon have ended the expansion of U-Verse and FiOS respectively, communities that need better networks for economic development should consider how they can invest in themselves.”

Verizon: The Future is Wired

An unfortunately common argument used against community fiber networks is that everything will be wireless in the future. This was used frequently last year in North Carolina by defenders of the pro-TWC legislation to create new barriers against community fiber networks.

The technical among us may want to get into the math theory with the Shannon-Hartley theorem to explain why wired is more reliable than wireless and therefore capable of much higher capacity.

Others might point that wireless will have less capacity because a wireless connection is really a wired connection to a tower somewhere that is then shared among hundreds or thousands of other users. Empirically, there is no wireless connection that beats fiber-optics.

But if you are looking for an entity that is intimately familiar with both wired and wireless, you might ask Verizon. Verizon is rolling out its LTE wireless network (arguably the best large scale wireless network in the country) and has millions of customers on its fiber-optic FiOS wired network. Verizon says the future needs fiber-optics to the home and wireless in the air:

"If you get underneath what's driving the fiber in the metropolitan markets it has been the need for increased video, increased reliability and security for customers," Seidenberg said. "The way we think about it is even though we have this great 4G mobile network, you still need to have fiber to the premises because we think your home will utilize a Gigabit of bandwidth."

...

"The way we look at it is we want to get fiber to as many business premises and cover as much as the footprint as we can and we believe everyone else going to do the same thing in other parts of the country," Seidenberg said. "If the incumbents or the MSOs don't do it then these little companies will do it and be the entrance facilities to homes and businesses."

As folks in North Carolina consider this year's proposal to limit competition with last-generation cable and DSL networks, they should think seriously about the communities around them served by FiOS -- with much faster speeds at much lower prices than anything their incumbents can offer.

Salisbury Discusses Motivation Behind Fibrant on TelecomTV

Michael Crowell, Fibrant's Director of Broadband Services, discusses the motivation behind their community fiber network (Fibrant), as well as some of the technology behind their GPON network. This is one of several similar interviews from TelecomTV.

In this interview, Crowell makes an important point: each community should not be building its own head end and should cooperate with each other to use the existing resources built by Wilson and Salisbury.

Comcast, Level 3, Peering, and a Bad Best Case Scenario

So Comcast and Level 3 are in a peering dispute following the Netflix partnership with Level 3 to distribute their streaming movie service. Studies suggest Netflix movie streaming has become a significant chunk of Internet traffic, particularly at peak times.

A quick primer on peering: the Internet is comprised of a bunch of networks that exchange traffic. Sometimes one has to pay another network for transit and sometimes (commonly with big carriers like Comcast and Level 3) networks have an agreement to exchange traffic without charging (one reason: the costs of monitoring the amount of traffic can be greater than the prices that would be charged). (Update: Read the Ars Technica story for a longer explanation of peering and this conflict.)

Comcast claims that Level 3 is sending Comcast 5x as much traffic as Comcast sends to Level 3 and therefore wants to charge Level 3 for access to Comcast customers. Of course, as Comcast only offers radically asymmetrical services to subscribers, one wonders how Level 3 could be 1:1 with Comcast…

At Public Knowledge, Harold Feld ties the dispute to network neutrality:

On its face, this is the sort of toll booth between residential subscribers and the content of their choice that a Net Neutrality rule is supposed to prohibit.  In addition, this is exactly the sort of anticompetitive harm that opponents of Comcast’s merger with NBC-Universal have warned would happen — that Comcast would leverage its network to harm distribution of competitive video services, while raising prices on its own customers.

Susan Crawford

Susan Crawford wrote a lengthier piece about Comcast, Netflix, network neutrality, set-top boxes and NBC that is well worth reading (as is just about anything she writes).

However, for the purposes of this post, we will assume the 5x traffic imbalance is true (and unique and that Comcast has no ulterior motive for charging Level 3 (and its partners like Netflix) a fee for anti-competitive reasons (like its own TV Everywhere service). I want to explore the world in which Comcast has pure motives to explain why even in that world, policy should address the market power of Comcast.

Comcast wants to charge Level 3 for access to their customers, which means that content distributed by Netflix has a disadvantage relative to content distributed by Comcast. Even before buying NBC (does anyone really expect the Obama Administration to halt this terrible merger?), Comcast owned content creators. In fact, it has long used its market power as a massive cable distributor to acquire a stake in channels -- as detailed here and here.

As a Comcast customer, it becomes harder and harder for me to choose content not owned by Comcast. Even if Comcast does not act anti-competitively, the content it owns is simply easier for me to find and access. This creates a barrier for new content providers (and encourages Netflix to give Comcast a stake in the company).

These inevitable barriers to entry, even when Comcast is not abusing its power exemplify the problems of massive scale for a company that owns both content and the (increasingly sole) means of transmitting it.

A far better arrangement is structural separation, where the network owner has no stake in the content transferred. This observation informs our preference for community owned networks -- ideally open access networks with a multitude of independent service providers. Even if Comcast behaves itself, it has too much control over the future of content -- from web sites to television programming.

Vermonters Angry at Wireless Broadband Stimulus Grant Instead of Fiber Loan

Vermonters are asking some hard questions about the federal broadband stimulus decision to throw money at a wireless network for Vermont rather than loaning money to an organization dedicated to delivering real broadband.

Senator Bernie Sanders convened a meeting to discuss the awards toward the end of October.

Senator Bernie Sanders led off his “broadband town meeting” Saturday morning at Vermont Technical College with a ringing affirmation of the need for better broadband coverage in Vermont and the nation.

However, nobody in the crowd of nearly 300 people needed to be convinced of that. What they wanted to know was whether a huge new federal grant to a private company was the right way to do it.

VTel, a small private telephone company, received a $116 million grant to build a FTTH network to serve their existing 18,000 footprint as well as a wireless network that is intended to serve the entire state.

In contrast, the East Central Vermont Fiber Network (which we have covered previously), applied for a loan to build a FTTH network to everyone in the 24 communities that have joined together to form the network. The ECFiber network would be run by a nonprofit and would repay the loan from revenue generated by selling triple-play services on the network.

Vermonters have a strong fiscal conservatism streak, which has shown up strongly in the discussions around this situation, something noted in a story leading up to the Sanders meeting:

He will get plenty of both from representatives of ECFiber, the consortium of 23 towns that has been planning a network of fiber-optic broadband to virtually every home in the White River Valley and beyond.

The organization was stung recently when its own request for a loan was not funded by RUS, which instead awarded a much larger outright grant to VTel, which is located in Springfield.

Our position at MuniNetworks, is quite similar to that of the these Vermonters: loans would be better policy than grants for broadband infrastructure.

Supporters of the wireless network, including VTel's CEO, Michel Guite, have suggested the $116 million grant will put Vermont at the head of the broadband pack (from story quoted above):

“The funding is in (this grant) to allow Vermont to make broadband available to everyone,” he said. “We would be the first state in the union” to do that.

“We’re not going to be behind any more; we’re going to be leading,” he proclaimed.

Unfortunately, this appears to be yet another case of wireless hype vastly exceeding the likely outcomes. A skeptical editorial from the Vermont Standard echoes the concerns of many more Vermonters with a rather understated fact:

Vermont

Vermont’s mountains and valleys are a significant barrier to universal wireless service.

Senator Sanders appeared to push VTel's CEO on the question, but reporter Dickie Drysdale caught the important qualifications in the exchange:

His first question was, “Will you bring broadband to every citizen in Vermont?” From Guité, the answer to this one was “Yes, but …”

Sanders quickly rephrased the question: “I want you to say, will you provide universal broadband service to every single unserved community in Vermont?”

Responding to this quite different question, Guité happily said “Yes, I will.”

Dickie goes on to quote David O'Brien, the Commissioner of Vermont's Public Service Department:

“This is a positive story for Vermont,” he said. This grant will help us.” Bringing fiber optic service to every point in Vermont “is not a possibility,” he said.

For those unfamiliar, O'Brien's record on broadband is hardly impressive. He allowed the disastrous Verizon-Fairpoint fiasco that has resulted in a marked decline in telephone reliability while customers were regularly overcharged.

We should be thankful O'Brien was not in a position of authority one hundred years ago, to assure everyone that universal electrical grids were "not a possibility." The reality is that FTTH to everyone in Vermont is not only a possibility, it is a certainty barring the end of human civilization. The idea that Vermonters will use copper in 50 years to communicate is absurd.

The question is when Vermonters will have access to fiber-optic networks -- and policy decisions to shower private companies with grants to build wireless networks rather than using loans to allow communities to build FTTH networks (that will be directly accountable them) will only delay the inevitable. An almost universal wireless network is a step forward for a state so far behind in communications infrastructure; but it will not be the envy of the nation and its pathetic reliable and speeds will not drive economic development.

Overblown claims about the capabilities of wireless led to a press release and white paper from ECFiber, which admitted "Wireless is 'Better than Dial-up,'" while admonishing "Fiber is 'Future Proof.'"

Wireless fixed broadband is simply not good enough. It has been tried in Vermont and it doesn’t work very well (just ask any user) – the gap between wireless and fiber will only widen in the future.

The white paper is real reality check for those who believe wireless will solve America's broadband problems:

Vermont’s mountainous topography presents real challenges to wireless broadband (both fixed and mobile.) Many cell sites will be required to achieve reasonable theoretical coverage rates using standard propagation models. (N.B., DO most Vermonters want hundreds of new ridgeline cell sites 30 feet above treeline? And how will all these cells in remote locales be connected with fiber to the Internet?) This theoretical coverage will be significantly reduced by local factors, especially foliage.

There are many ECFiber pre-registrants that live in areas nominally “covered” by fixed wireless Internet service providers (“WISPs”) but are unable to access their services because of local topography or foliage constraints. Those that have access to fixed wireless acknowledge that it is “better than dial-up” but are not happy with the service’s reliability or speed. Advertised speeds are often not achieved (particularly for users on the edge of a cell site or without line-of-sight) and speeds drop significantly during busy hours.

Many have noted that they both need and desire to stream video over their broadband connection -- especially at the Vermont Law School. But the wireless broadband from VTel will almost certainly fail to do that reliably.

VTel's CEO told Vermont Public Radio that he would have loved to run fiber-optics through all of Vermont:

"But all of Vermont would cost a billion dollars and nobody was offering that."

No one should offer that!! We aren't talking about charity here. This is infrastructure! This is exactly how the private-sector mindset that fails to understand the nature of infrastructure. Broadband networks are not the product, they enable all other products. They are essential for commerce, as well as education, and soon for health care. Infrastructure should be paid for the public that benefits from it, as the roads are. And when the costs are too large for the community, the federal government can help with long term loans, and perhaps grants where essential.

ECFiber understands this. And while ECFiber would not have connected all of Vermont with a single broadband stimulus award, it would have solved the communications infrastructure problem for these 24 towns for at least one, and probably several more, generations. It would have expanded to cover more Vermonters, as we have seen community fiber networks do elsewhere recently (often with stimulus awards).

The supreme irony of the massive federal grant to VTel is that it may result in Vermonters having to wait longer to get universal access to real broadband. Any entity, public or private, will find it more difficult to pay for the costs of building a network in Vermont because the wireless network will provide good enough service for those with good line-of-sight to the towers. Having lost those customers, a proper network will have fewer potential takers, making it more difficult to justify the costs.

This was our concern when we first learned of the broadband stimulus program. Giving out grants to private companies who will provide "better than dial-up" service is an extremely poor use of our tax dollars. It solves no long term problem; it really makes the longer term problems more difficult to solve.

But what does VTel care? No one was going to pay them to build fiber to everyone anyway, right?

Fortunately, ECFiber is moving forward with a pilot project expected to break ground in the spring.

Another Chattanooga Update

Chattanooga continues to generate a lot of press since their announcement of the nation's fastest broadband speeds.

For those who crave technical details, this article from Cable 360 looks into the tech behind the network:

EPB contracted with Alcatel-Lucent as its GPON network supplier. "We've designed our network a little bit different, with our control center located where our operations center is," says Wade. "We've designed a series of fiber rings that circle our city, allowing us to have multiple 10 Gig MPLS rings, terminating in 17 communications hubs connected back with our control center."

Another article from Cable 360 (affiliate) gets into the smart-grid details of the network:

As far as the cost savings of the smart grid are concerned, users often don't realize that it costs several times more at certain times of day to generate electricity than it does at others, says EPB COO David Wade.

But perhaps the most interesting update from EPB is another window into their take rates (from Tecca.com):

We are ahead of our business plan projections for this time frame. Since our launch last September (2009), we have signed up 18,873 homes to our EPB fiber optics services. That is a 15.45% take rate. Our goal is a 35% take rate, and we believe we will reach that in 2 years. Of our EPB fiber optics customers, 81% are receiving our Fi-Speed internet service. We are still building out fiber optics as well, and our entire 600-square-mile customer service area will have access to these advanced services by the end of the this year (2010).

And finally, a short interview (audio quality is not good) with an EPB employee discussing Chattanooga's community fiber network. An interesting piece: noting that EPB views all employees as ambassadors of their product and offered them public speaking training.
