The Network Management Excuse

Telco front-man Scott Cleland, in a recent blog post, thumbs his nose at the Four Internet Freedoms and says that the FCC should too. Under current leadership, it probably will. Referring to the recent submissions to the FCC by Free Press and Public Knowledge and Vuze complaining about Comcast's use of reset packets to block applications that compete with Comcast's own proprietary video entertainment offering, Cleland says "Network management trumps net neutrality." There are lots of reasons for, ahem, managing. Cleland neglects to observe that controlling congestion the way Comcast does it is like scattering nails in the road for traffic control. more

Up to 300 Megawatt Worth of Keepalive Messages to be Saved by IPv6?

The Time Square Ball bringing in 2008 had more than 9,500 LED bulbs displaying 16 million colours while consuming power equivalent to about ten toasters. This compares to 600 incandescent and halogen bulbs adorning last year's Ball. Easy to forget that most mobile devices used by Time Square revelers were behind IPv4 NAT's and that always on applications such as Instant Messaging, Push e-mail, VoIP or location based services tend to be electricity guzzlers. It so happens that applications that we want always to be reachable have to keep sending periodic keepalive messages to keep the NAT state active... more

“The Broadband Revolution”

The International Telecommunications Union recently issued a press release announcing with joy the release of "the first set of global standards for Internet Protocol TV (IPTV)." A key sentence: "A combination of voice, Internet and video services over a single broadband link and from a single provider is foreseen as the ultimate goal of the broadband revolution." Those of you who lived through 'What Is Broadband Good For?' with me last summer, know that the word "broadband" is a pet bugaboo of mine. It's a word that answers a lot of policy questions in a particular way. more

Will 2008 be the WiMAX Year?

There has recently been some good and bad news about WiMAX. On the good news part, an announcement made by the WiMAX Forum this month regarding the launching of the Mobile WiMAX certification program through which vendors can get their IEEE 802.16e-2005 equipment tested and possibly certified... On the bad news part, there was the Sprint-Clearwire breakup after three months of announcing a plan to join forces in building a nationwide WiMAX network in the US. Although it is anticipated that each company would carry on with its own WiMAX plans, analysts believe that the breakup would have negative impact on WiMAX deployment in the US... more

DNSSEC: Once More, With Feeling!

After looking at the state of DNSSEC in some detail a little over a year ago in 2006, I've been intending to come back to DNSSEC to see if anything has changed, for better or worse, in the intervening period... To recap, DNSSEC is an approach to adding some "security" into the DNS. The underlying motivation here is that the DNS represents a rather obvious gaping hole in the overall security picture of the Internet, although it is by no means the only rather significant vulnerability in the entire system. One of the more effective methods of a convert attack in this space is to attack at the level of the DNS by inserting fake responses in place of the actual DNS response. more

Telecommunications Advocacy: Who’s Behind That Blog?

An assignment in a Media and Democracy course I teach at Penn State invites students to select a telecommunications advocacy web site for analysis. I want my students to decode the message and attempt to identify whether a bias exists and who financially supports the site. The exercise typically fails miserably... Most students cannot infer that a site that advertises books by Ann Coulter trends to the right and one that talks about social justice trends to the left. more

Verizon OPEN Wireless

Very surprising and welcome announcement from Verizon Wireless yesterday announcing that "it will provide customers the option to use, on its nationwide wireless network, wireless devices, software and applications not offered by the company. Verizon Wireless plans to have this new choice available to customers throughout the country by the end of 2008..." And Verizon Wireless is right to open up. There's plenty of room to be cynical about this; after all, Verizon Wireless is trying to STOP the FCC from putting an openness requirement on the 700Mhz spectrum to be auctioned... more

In Praise of Relatively Dumb Pipes

Comcast's furtive and undisclosed traffic manipulation reminds me of a curious, red herring asserted by some incumbent carriers and their sponsored researchers: that without complete freedom to vertically and horizontally integrate the carriers would lose synergies, efficiencies and be relegated to operating "dumb pipes."... Constructing and operating the pipes instead of creating the stuff that traverses them gets a bad rap. It may not be sexy, but it probably has less risk. But of course with less risk comes less reward, and suddenly no one in the telecommunications business is content with that. So incumbent carriers assert that convergence and competitive necessity requires them to add "value" to the pipes. more

FCC Chairman Martin a Tireless Consumer Advocate - Who Knew?

In a counter-intuitive move for a Republican free marketeer, FCC Chairman Kevin Martin has sought to impose substantial additional regulations on cable television. Chairman Martin ostensibly can retain his credentials by claiming that a 1984 law requires the FCC to act when cable television systems serve 70% or more of the U.S. population and 70% who can subscribe do so. more

Bandwidth Demands Exceeding Internet Infrastructure Investment

Nemertes Research has released a report on the future of the Internet infrastructure. The key finding from the report is that bandwidth demands are exceeding infrastructure investment, especially at the access layer. We noted in the project that users may begin to see the impact of degraded application performance as early as 2010. We also noted that the planned investments in Internet infrastructure are insufficient to meet growing demand. more
