Internet Traffic Exchange: Time to Look under the Hood

No one company defines your personal Internet experience. The Internet Service Providers (ISPs) that sell you Internet access are only one part of a complex ecosystem that also includes backbone providers, content delivery networks, and other Internet traffic actors. The connection points between and among these groups have many names: peering, transit, proxy services, interconnection, or traffic exchange.

Here’s why those connection points matter to consumers: let’s say you’re trying to watch a video on YouTube. To get from YouTube servers to your computer, the video has to traverse a number of networks in order to get to your ISP, and ultimately to get to your computer. If the video can’t stream efficiently from network to network along its way to your ISP, your viewing experience may suffer as a result.

It has become clear from consumer complaints to the FCC—and even in some comments consumers have filed for the Open Internet NPRM—that consumers are frustrated by recent trouble with their Internet experience for certain services and content providers. The recent disputes between Netflix, Cogent and ISPs such as Comcast and Verizon are an example of this issue.

We need to get to the bottom of this.

Last week, Chairman Wheeler announced that he has directed the Commission staff to obtain the information we need to understand precisely what is happening in order to understand whether consumers are being harmed. Commission staff has begun requesting information from ISPs and content providers.

FCC Announces Public Testing of First Television White Spaces Database

White spaces are unused spectrum between TV stations and are considered prime real estate because signals in this band travel well, making the band ideally suited for mobile wireless devices. Unlocking this valuable spectrum will open the doors for new industries to arise, create American jobs, and spurr new investment and innovation. 

The availability of spectrum for unlicensed devices has fueled a wave of innovation and new businesses based on technologies such as as Wi-Fi, Bluetooth, DECT cordless phones, baby monitors, RF ID, smart utility meters, and many others.  This new unlicensed spectrum is powerful platform for innovation and in turn, experimental use, holding rich potential for further investment in the development of new technologies and services such as "Super Wi-Fi", wireless broadband networks, video devices, and machine to machine communications, among others.   

Today, the Commission is taking a critical step towards that goal by issuing a public notice announcing the start of the first trial of a TV white spaces database. The limited public testing of Spectrum Bridge’s database system is intended to allow the public to access and test the system to ensure that it correctly identifies channels that are available for unlicensed TV band devices, properly registers those facilities entitled to protection, and provides protection to authorized services and registered facilities as specified in the rules.
