Neustar and .GPRS

Ever since Neustar announced they signed a deal with GSMA to oversea global database for the mobile operators last week (see also Washington Post), there are many debates about the deal online. "Neustar, a company that should certainly know better, has announced that they're going to create a .gprs TLD to serve the mobile phone industry This, of course, requires creation of a private root zone, against the very strong warnings in RFC 2826" said Steven Bellovin. To the more supportive John Levine: "This isn't quite as stupid as it seems. The GSM industry needs some way to maintain its roaming user database, the database is getting considerably more complicated with 3G features, and it looks to me like they made a reasonable decision to use DNS over IP to implement it rather than inventing yet another proprietary distributed database." more»

Road Warrior at Risk: The Dangers of Ad-Hoc Wireless Networking

Most people who have wireless Ethernet at home, or the office, connect to the wireless network by attaching to a wireless Access Point, or AP. This method of wireless networking is called "Infrastructure Mode". If you have a secure wireless network configured in "Infrastructure Mode" you are using MAC address filtering, some level of encryption, and have made some additional changes to your AP in order to prevent just anyone from using it or capturing data. ...However, for those who are not using "Infrastructure Mode", and are configured to communicate from machine to machine, or "Ad-Hoc", there are a few things you should be aware of. more»

Monetizing the Internet

What would duopoly providers of internet access really like to have? They'd really like to be paid for providing non-commodity services. They'd really like to be rewarded for running the network, top to bottom. "But that's not possible," you say. No provider can tell one packet from another. Providers can only block the ports used by applications they don't like, and that's a clumsy, unwinnable arms race. The applications can always switch to common and useful ports, and no provider wants to alienate its subscriber base. But what if providers could inspect the contents of packets, without using too much computational power, and discriminate among applications? "Naah," you say. "They can't possibly do that."... more»

Twenty Myths and Truths About IPv6 and the US IPv6 Transition

After hearing over 350 presentations on IPv6 from IPv6-related events in the US (seven of them), China, Spain, Japan, and Australia, and having had over 3,000 discussions about IPv6 with over a thousand well-informed people in the IPv6 community, I have come to the conclusion that all parties, particularly the press, have done a terrible job of informing people about the bigger picture of IPv6, over the last decade, and that we need to achieve a new consensus that doesn't include so much common wisdom that is simply mythical. There are many others in a position to do this exercise better than I can, and I invite them to make a better list than mine, which follows. more»

Internet Governance: Analogue Solutions to Digital Problems

This is an overview of the booklet, "Internet Governance: Issues, Actors and Divides," recently published by DiploFoundation and the Global Knowledge Partnership. "Internet Governance is not a simple subject. Although it deals with a major symbol of the DIGITAL world, it cannot be handled with a digital - binary logic of true/false and good/bad. Instead, the subject's many subtleties and shades of meaning and perception require an ANALOGUE approach, covering a continuum of options and compromises." Update: This article was reposted with additional information and a new title. more»

Why Do We Care About Names and Numbers?

An article based on the most recent study for the European Commission on the Policy Implications of Convergence in the Field of Naming, Numbering and Addressing written by Joe McNamee and Tiina Satuli of Political Intelligence.

"With relation to the Internet and also IP addresses, the "scarcity" is more complicated: there are not only intellectual property issues with regards to domain names, but there is also an issue of managing the integrity of the system. For any naming or numbering system to work, it is essential that the names and addresses used cannot be confused with any other -- in other words, no one system can have two end-points with the same fully qualified number or name..." more»

Exposing 9 Myths About IPv6

This is a special two-part series article providing a distinct and critical perspective on Internet Protocol Version 6 (IPv6) and the underlying realities of its deployment. The first part gives a closer look at how IPv6 came about. This part exposes the myths.

Good as all this is, these attributes alone have not been enough so far to propel IPv6 into broad-scale deployment, and consequently there has been considerable enthusiasm to discover additional reasons to deploy IPv6. Unfortunately, most of these reasons fall into the category of myth, and in looking at IPv6 it is probably a good idea, as well as fair sport, to expose some of these myths as well. more»

Ye Olde DNS

I've been writing about the intrinsic problem with the use of the DNS as both a technical mechanism and as a source of unambiguous meaning and authority. The problems are much worse than most of the posters seem to note. The current approach assures that the Internet will unravel and worse, that URLs become perversely reused. The commercial terms of service associated with the use of ".com" names exacerbates the problem by imposing arbitrary social policies into the plumbing of the Internet. more»

Mobile Trumps Fixed Broadband

"80% of Web users will choose mobile broadband over fixed by 2013" is the headline of a Total Telecom interview with John Cunliffe of Ericsson. I agree with the conclusion although I think Ericsson will be unpleasantly surprised to find that LTE is NOT the technology which leads to this revolution. Mobile access at speeds at least equal to what cable offers and at a price lower than today's cable broadband will be available both in the home and on the road within a year or two at the most. more»

TV White Spaces Just the Beginning: Secondary Use of the Spectrum

Yesterday, the US Federal Communications Commission (FCC) voted to allow qualified devices to operate on a license-exempt basis in unused portions of TV channels 2-51, spectrum commonly referred to as "TV white spaces." A lot has already been written about this move... But what is missing in these discussions is the bigger picture. more»

FCC Approves White Space Devices: The Dawn of the Age of Opportunistic Spectrum Reuse

Yesterday will go down in history as a bellwether moment. Few among us will soon forget the excitement of Obama's election. But there was an equally historic vote yesterday that for geeks, policy analysts, and technologists represents an entirely new trajectory in telecommunications. In essence, the FCC has begun the transition from command-and-control, single-user spectrum licensure to a more distributed system that holds the potential to eliminate the artificial scarcity that prevented widespread access to the public airwaves since 1927. more»

FCC Approves White Space for Broadband in Unanimous Vote

The Federal Communications Commission (FCC) today approved, in a 5-0 unanimous vote, the plan to open up unused, unlicensed portions of TV white space spectrum for wireless applications and devices. However, to prevent interference, FCC has also placed some "rigorous certification process" which device offered by a technology company for use on the white spaces will have to go through. more»

FCC Vote Results: We the People Won

The Federal Communications Commission (FCC) has just voted to open up the so called TV Whitespaces for UNLICENSED use. This is incredibly good news for rural America in particular but actually for all of America. It's not as important as the election the rest of us in the US voted in today -- but this action is a very, very big deal. Just a few of the benefits... more»

The Real White Spaces Debate: To Create or Abolish a Market in the Airwaves

I've been following the "white spaces" for as long as it has been happening -- four, maybe five years -- and I must admit that I am surprised by FCC Chairman Kevin Martin's sudden fondness for them. Until the last days of his chairmanship, Martin never cared for this somewhat radical notion: allowing techies and community activists to spew electromagnetic frequencies in zones currently occupied (at least ostensibly) by the broadcasters. more»

The Trouble with White Spaces

Like several other engineers, I'm disturbed by the white spaces debate because it focuses on what I regard as the wrong question. The White Space Coalition argues that showing that a system can be constructed that prevents interference between White Space Devices and television broadcast signals compels the Commission to offer up the White Spaces for unlicensed use. This is far from obvious. more»
