Find: How big telecom smothers city-run broadband

It's against nc law for public government to provide internet service — even if no private service is available. 

The FCC is considering changing this.

This story was written and published by The Center for Public Integrity, a nonprofit, nonpartisan investigative news organization in Washington, DC, and is exclusively republished here.

Janice Bowling, a 67-year-old grandmother and Republican state senator from rural Tennessee, thought it only made sense that the city of Tullahoma be able to offer its local high-speed Internet service to areas beyond the city limits.

After all, many of her rural constituents had slow service or did not have access to commercial providers, like AT&T Inc. and Charter Communications Inc.

Find: IPv6 adoption starting to add up to real numbers: 0.6 percent

The paper behind all this looks interesting. 


IPv6 adoption starting to add up to real numbers: 0.6 percent
// Ars Technica

Packets on packets...

In a paper presented at the prestigious ACM SIGCOMM conference last week, researchers from the University of Michigan, the International Computer Science Institute, Arbor Networks, and Verisign Labs presented the paper "Measuring IPv6 Adoption." In it, the team does just that—in 12 different ways, no less. The results from these different measurements don't exactly agree, with the lowest and the highest being two orders of magnitude (close to a factor 100) apart. But the overall picture that emerges is one of a protocol that's quickly capturing its own place under the sun next to its big brother IPv4.

As a long-time Ars reader, you of course already know everything you need to know about IPv6. There's no Plan B, but you have survived World IPv6 Day and World IPv6 Launch. All of this drama occurs because existing IP(v4) addresses are too short and are thus running out, so we need to start using the new version of IP (IPv6) that has a much larger supply of much longer addresses.

The good news is that the engineers in charge knew we'd be running out of IPv4 addresses at some point two decades ago, so we've had a long time to standardize IPv6 and put the new protocol in routers, firewalls, operating systems, and applications. The not-so-good news is that IP is everywhere. The new protocol can only be used when the two computers (or other devices) communicating over the 'Net that are talking to each other—as well as every router, firewall, and load balancer in between—have IPv6 enabled and configured. As such, getting IPv6 deployed has been an uphill struggle. But last week's paper shows us how far we've managed to struggle so far.

Find: Netflix sends 99 percent of its traffic over free connections to ISPs

Only in the us does netflix have to pay to cross the last internet mile — meaning that at least for netflix, the us is less net neutral than other countries. 


Netflix sends 99 percent of its traffic over free connections to ISPs
// Ars Technica

Netflix hates writing checks to Internet service providers—and luckily enough, it usually doesn't have to.Though the streaming video company has complained bitterly about having to pay Comcast, AT&T, Verizon, and Time Warner Cable for direct connections to their networks, Netflix said this week that worldwide, it delivers 99 percent of its traffic without money changing hands.

The statement came in a filing with the Federal Communications Commission in which Netflix asks the FCC to block Comcast's proposed acquisition of Time Warner Cable. Besides AT&T and Verizon, those are the only ISPs that refused to give Netflix the unpaid connections, known as "settlement-free peering." In the months before Netflix agreed to pay these companies, video was sent over congested links, resulting in poor performance for subscribers.

To Netflix, the fact that so few companies have the market power (i.e. size) to demand such payments is evidence that further consolidation should not be allowed. Netflix goes into its thinking in more depth than it has previously, but it's the same argument that it has made before. What's surprising is the statement that nearly all of Netflix's traffic goes over unpaid connections to ISPs, despite Netflix having to pay the four biggest in the US.

Find: Comcast aims to hook college students on cable with TV over Wi-Fi

Comcast aims to hook college students on cable with TV over Wi-Fi
// The Verge - All Posts

Comcast today formally announced a new service that will let college students at seven universities stream live TV and video on-demand programming across their personal laptops, smartphones, and tablets while connected to campus Wi-Fi. Dubbed Xfinity On Campus, the service is included as part of each student's room and board fees — which means it's also only available to those residing in on-campus housing.

The whole effort is squarely aimed at millennials who are spending more and more time watching their favorite shows and movies away from a TV set. Comcast wants to get these younger college viewers — many of whom are perfectly content living in a world of Netflix, Hulu Plus, and shared HBO Go logins — hooked on cable in hopes that...

Find: The worst company in America

Nice summary of the state of internet access in the us. 

The worst company in America
// The Verge - All Posts

Comcast’s corporate headquarters, Comcast Center, is the tallest building in Philadelphia. It’s covered in mirrors, which makes it the perfect metaphor for the company, one former employee says; no matter where you go, the glare is in your eyes.

It seems a lot of people share that sentiment.

Comcast earned Consumerist’s “Worst Company in America” title twice, first in 2010 and again this year, 2014. It ranks at the very bottom of the American Consumer Satisfaction Index, underperforming...

Find: The internet is so big that it's breaking routers

More growing pains for the net. 

// The Verge - All Posts

The internet may soon be too large for many border routers to handle, according to a new report from analysts at Renesys. Older hardware could reach a breaking point in the next few weeks, causing failures across smaller providers. It's going to be more of an inconvenience than a catastrophe, but if your small provider goes down in the coming weeks, there's a good chance there'll be an overloaded border router behind it.

Internet routers hitting 512K limit, some become unreliable

Internet routers hitting 512K limit, some become unreliable
// Ars Technica

From performance issues at hosting provider Liquid Web to outages at eBay and LastPass, large networks and websites suffered a series of disruptions and outages on Tuesday. Some Internet engineers are blaming the disruptions on a novel technical issue that impacts older Internet routers.
At the heart of the issue, the growth of routable networks on the Internet overwhelmed the amount of memory set aside in infrastructure hardware, typically routers and switches, that determines the appropriate way to route data through the Internet. For the first time, the lists of routable networks—also called border gateway protocol (BGP) tables—surpassed a significant power of two (two to the 19th power or 512K). Many older routers limit their use of a specialized, and expensive, type of memory known as ternary content-addressable memory (TCAM) to 512K by default.
When the tables outgrew the space allotted for them, the routers shut down or slowed.
