Packet Loss: How the Internet Enforces Speed Limits

There's been a lot of controversy over the FCC's new Network Neutrality rules. Apart from the really big issues -- should there be such rules at all? Is reclassification the right way to accomplish it? -- one particular point has caught the eye of network engineers everywhere: the statement that packet loss should be published as a performance metric, with the consequent implication that ISPs should strive to achieve as low a value as possible. more

Email’s Not Dead, Neither is Spam

Over the past few years, we have seen a plethora of over-hyped articles in the popular press and blogosphere crowing wrong-headedly about how 'email is dead'. Social networks like Facebook and Twitter, new and as-yet unproven technologies are the supposed death-knell for our old reliable friend, e-mail. I wrote about the rumours of email's death being exaggerated back in 2007 in response to such inanity. Since then, we've seen such a cornucopia of silliness of the 'Such & such is killing email' variety that Mark Brownlow compiled a bunch of articles, and their rebuttals at his excellent site... more

Google Finds Nothing is Shovel Ready, Not Even for Free Fiber Build

Google is deploying fiber at its own expense in Kansas City, Kansas and Kansas City, Missouri to demonstrate the value of one gigabit (a gigabit is a billion bits -- a lot) per second residential Internet connections and perhaps to show at&t and Verizon and the cable companies how the search giant might fight back if its growth is restricted by their restrictions or limitations. ... Whoops. Google just learned the same lesson that President Obama learned in Stimulus 1 more

Don’t Overlook the Network When Migrating to the Cloud

The success or failure of public cloud services can be measured by whether they deliver high levels of performance, security and reliability that are on par with, or better than, those available within enterprise-owned data centers... IDC forecasts that public cloud IT spending will increase from $40 billion in 2012 to $100 billion in 2016. To provide the performance, security and reliability needed, cloud providers are moving quickly to build a virtualized multi-data center service architecture, or a "data center without walls." more

10 Years Since the Internet Was Changed Forever

On Saturday, you were probably enjoying a quiet morning, sipping your coffee as you consumed headlines about news from New York to New Delhi. The headlines related to Internet business were probably much different than what you would have seen 10 years ago. Then, there were just 20 million domain names in use, ten percent of what is now our domain universe. But ten years ago, many of us in the industry weren't enjoying an easy morning with our coffee; we were harried from a sleepless night of poring over hundreds of pages that would constitute the first new Top-Level Domain (TLD) bids submitted to ICANN, ever. more

Lawyer-Impersonator Pleads Guilty over False C&Ds

As if there weren't enough problems with lawyers sending out improper cease-and-desists, Wired News reports that a Nevada man has pleaded guilty to impersonating a lawyer to extort domain registrants to turn over their domain names. "A Nevada man pleaded guilty Thursday to his plotting to steal domain names from their legitimate owners by impersonating a California intellectual property lawyer and send threatening letters to domain name owners in hopes of convincing them to turn over the domains to him..." more

How to Abolish the DNS Hierarchy… But It’s a Bad Idea

There's been a fair amount of controversy of late about ICANN's decision to dramatically increase the number of top-level domains. With a bit of effort, though and with little disruption to the infrastructure -- we could abolish the issue entirely. Any string whatsoever could be used, and it would all Just Work. That is, it would Just Work in a narrow technical sense; it would hurt innovation and it would likely have serious economic failure modes. more

Are Botnets Really the Spam Problem?

Over the last few years I've been hearing some people claim that botnets are the real spam problem and that if you can find a sender then they're not a problem. Much of this is said in the context of hating on Canada for passing a law that requires senders actually get permission before sending email. Botnets are a problem online. They're a problem in a lot of ways. They can be used for denial of service attacks. They can be used to mine bitcoins... more

Lessons from Egypt: We Need to Protect Our Connected Minds

We need to protect the power that allows us to connect our collective intelligence, as described a few weeks ago in my blog on connected minds. I argued that in order to address some of our global challenges we have to start looking at a radically new way to address them. The events in Egypt brought home the fact that if it comes to the crunch any government can disconnect us simply by bringing the Internet and other communications systems down at will... more

ICANN at a Crossroads: GDPR and Human Rights

The European Data Protection Board certainly has been keeping its records straight. Its 27 May statement starts with the following: "WP29 has been offering guidance to ICANN on how to bring WHOIS in compliance with European data protection law since 2003." All internet users have dealings with the Internet Corporation for Assigned Names and Numbers, yet the vast majority have never heard of ICANN. more

Google’s New Public DNS Service - and Data Retention Issues

In a move potentially of significant importance to the vast majority of Internet users who do not run their own DNS servers to resolve Internet site domain names, Google announced their own publicly accessible DNS service. Unlike some other publicly accessible DNS services that may redirect nonexistent domain queries for advertising purposes, Google explicitly states that "Google Public DNS never blocks, filters, or redirects users." more

ICANN Meeting: The Road to Wellington

What would it take for this upcoming meeting to be a success? I am a big believer in ICANN's core principles, and in the forum it provides for private self-governance of domain names and numbers. I think the ICANN model continues to have great potential as a form of governance. For this meeting to be a success for me, personally, I'd like to see those core principles made more visibly operational -- or at least see a start made on this effort. I'm putting a stake in the ground with these posts, and we'll see whether progress happens or not. more

New, Old and Forgotten Frames in the Network Neutrality Debate

One key reason for confusion about Network Neutrality lies in the many different and inconsistent frames used to shape the debate. The Tea Party has entered the fray by characterizing the matter primarily in terms of freedom. Republicans decry the "job killing" impact of the FCC's rules. Network Neutrality advocates appear ambivalent whether the FCC has capitulated to special interests, or shaped a pragmatic compromise. more

Cable Trounces the Telcos

Yesterday, Netflix posted graphs of how well various ISPs deal with Netflix video streams. The results are striking. All the cable companies easily beat all the phone companies with the exception of Verizon where we're seeing a mix of DSL and FiOS results. more

The Test of Time at Internet Scale: Verisign’s Danny McPherson Recognized with ACM SIGCOMM Award

The global internet, from the perspective of its billions of users, has often been envisioned as a cloud -- a shapeless structure that connects users to applications and to one another, with the internal details left up to the infrastructure operators inside. From the perspective of the infrastructure operators, however, the global internet is a network of networks. It's a complex set of connections among network operators, application platforms, content providers and other parties. more
