Would the Real Network Neutrality Please Stand Up?

I'm sure this is something that's been raked over before, but I don't see a common understanding of what 'Net Neutrality' actually is. Despite many of the Internetorati demanding it by law. There appear to be several different camps, which you could paint as "bottom of IP", "middle" and "top". The bottomistas would see enforced Internet Protocol itself as a premature optimisation and violation of the end-to-end principle. Unhappy that you only get IPv4 or IPv6? Still grumpy that you only have IPv4 and not even IPv6? Really miserable that your VoIP packets are staggering under the poisonous load of IPv6 headers? You're a bottomista. more

Vint Cerf Speaking Out on Internet Neutrality

In a U.S. congress hearing held yesterday November 9th, significant focus was projected on "network neutrality" and a new telecommunications bill affecting the Internet. "This bill could fundamentally alter the fabulously successful end-to-end Internet," says Alan Davidson in the post on Google blog. Vint Cerf was not able to testify because of the Presidential Medal of Freedom award ceremony at the White House, but submitted the following letter to the hearing... more

The Great Internet Transformation? A First Stab

Is it just a coincidence that some of the leading Internet-based application companies are pushing aggressively into network connectivity at exactly the same time the major telephone companies are pushing into content? Or are we witnessing the end of the Internet as we know it? Think back to the online world fifteen years ago. There was AOL, there was Compuserve, there was Prodigy, and there was Apple's eWorld. Sure, there were researchers and students posting to Usenet newsgroups and navigating through Gopher sites, but the Internet was a sideshow for individuals and business users. ...the online world of those days was fragmented and small. Every online service was an island. Are we going back to those days? more

About Those Root Servers

There is an interesting note on the ITU Strategy and Policy Unit Newslog about Root Servers, Anycast, DNSSEC, WGIG and WSIS about a presentation to ICANN's GAC. (The GAC website appears to be offline or inaccessible today.) The interesting sentence is this: Lack of formal relationship with root server operators is a public policy issue relevant to Internet governance. It is stated that this is "wrong" and "not a way to solve the issues about who edits the [root] zone file." Let's look at that lack of a formal relationship... more

There Is No "Spam Problem"

This month I thought I could feel smug, deploying Postfix, with greylisting (Postgrey), and the Spamhaus block list (SBL-XBL) has reduced the volume of unsolicited bulk commercial email one of our servers was delivering to our clients by 98.99%. Alas greylisting is a flawed remedy, it merely requires the spambots to act more like email servers and it will fail, and eventually they will... 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

Averting the Internet Meltdown

A call to action went out: a small, California-based organization called People for Internet Responsibility (PFIR) posted an announcement for an urgent conference - "Preventing the Internet Meltdown." The meltdown that PFIR envisioned was not an impending technical malfunction or enemy attack. Instead, conference organizers foresaw "risks of imminent disruption" to the Internet that would come from an unlikely sector: government officials and bureaucrats working on the unglamorous-sounding problems of Internet Governance. more

Phone Always Busy? Must be DDoS on VoIP Network

Amidst the fascinating news from the SCO saga, preparing for SANS London and contributing to the Unix timeline project at Grokline my eyes caught a piece of rather distressing news on the BBC. It appears that BT (British Telecom) intends to move its current phone network to an IP-based network by 2009 thereby sending the circuit-switched technology off to the attic. The real question is: can we guarantee the same level of reliability on VoIP as we had on circuit-switched telephony when the stated aim is to carry both voice and data traffic down the same cables (or fibres more likely)? more

U.S. Moving Forward with ENUM

One of the pieces of infrastructure that makes all kinds of networks work and yet gets very little attention is the directory. Directories are big business. For example, there's directory of telephone numbers run by NeuStar, Inc. NeuStar has annual revenues of $92 million. Now, according to Light Reading, AT&T Corp. and MCI Inc., together with unidentified cable companies, telephone companies, and ISPs are preparing to form a Limited Liability Corporation (LLC) that will run a process to define a new company that will run ENUM. more

It's About Connectivity Not The Internet!

I've been trying to avoid writing about the Internet as such. With as "At the Edge" I'm looking at larger issues but can't escape writing more directly about the Internet. It seems as if everyone wants a say in Internet policy without distinguishing between technical and social issues. Today the term "The Internet" or, for many simply "Internet" is more of brand than a term for a specific technology and its implications. It has become too easy to talk about the Internet in lieu of understanding. We also see the converse -- a failure to recognize "Internet" issues. more
