Moving Beyond Telephone Numbers - The Need for a Secure, Ubiquitous Application-Layer Identifier

Do "smart" parking meters really need phone numbers? Does every "smart meter" installed by electric utilities need a telephone number? Does every new car with a built-in navigation system need a phone number? Does every Amazon Kindle (and similar e-readers) really need its own phone number? In the absence of an alternative identifier, the answer seems to be a resounding "yes" to all of the above.

Removing Need at RIPE

I recently attended RIPE 66 where Tore Anderson presented his suggested policy change 2013-03, "No Need -- Post-Depletion Reality Adjustment and Cleanup." In his presentation, Tore suggested that this policy proposal was primarily aimed at removing the requirement to complete the form(s) used to document need. There was a significant amount of discussion around bureaucracy, convenience, and "liking" (or not) the process of demonstrating need. Laziness has never been a compelling argument for me and this is no exception.

Video: Have We Found the Cure for Bufferbloat?

Following up on my recent post about how solving the Bufferbloat problem could dramatically increase the speed of Internet usage, I recently learned via a Google+ post by Michael Richardson of this video of a presentation by Jesper Dangaard Brouer of Red Hat at the recent DevConf.cz Brno 2013 titled "Beyond the existences of Bufferbloat - Have we found the cure?"

Live Today - “IPv4 Exhaustion and the Path to IPv6” from INET Denver

If you are interested in the current state of IPv4 address exhaustion within North America as well as the current state of IPv6 deployment, there will be a live stream today, April 17, of the sessions happening at INET Denver starting at 1:00pm US Mountain Daylight Time (UTC-6). The event is subtitled "IPv4 Exhaustion and the Path to IPv6" and you can view the live stream at.

The International Space Station’s Canadian Music Video Collaboration - and Google+ Hangout

As much as we talk here about the inner workings of the Internet's infrastructure, there are times when you have to just sit back and look at how incredibly cool some of the things are that are enabled by the Internet. For example, last week I was delighted to stumble across this excellent music video collaboration between the International Space Station's Canadian commander Chris Hadfield, the Canadian band Barenaked Ladies along with a Canadian student choir.

30 Years Ago Today, the Switch to TCP/IP Launched Today’s Internet

It was 30 years ago today, on January 1, 1983, that the ARPANET had a "flag day" when all connected systems switched from using the Network Control Protocol (NCP) to the protocols known as TCP/IP. This, then, gave rise to the network we now know as the Internet.

The Future of Home Networking: A Problem Statement

I'm a network engineer, and like many engineers I often gravitate to the big projects; large networks with problems of scale and complexity in my case. However, I also consider myself a student of Occam's razor and often quote Antoine de Saint-Exupéry: "perfection is reached not when there is nothing left to add, but when there is nothing left to take away." In this spirit of "less is more" I have recently become intrigued by the problems appearing in home networking.

IETF 85 Begins Next Week In Atlanta - Here Is How To Follow Along

The 85th meeting of the Internet Engineering Task Force (IETF) begins next week in Atlanta, Georgia, USA. Over 1000 engineers, maybe as many as 1400 or more, from all around the world will gather in various working groups to discuss and debate issues relating to the open standards that define the Internet's infrastructure.

Update on AS Path Lengths Over Time - How Interconnected is the Internet?

With the number of ASes connected to the Internet constantly increasing, one could expect that the length of the AS paths would also increase as the network as a whole gets wider. However, this doesn't seem to be the case. Also, with IPv6 being more widely deployed, how does the interconnectedness of the IPv6 portion of the Internet compare to IPv4?

OpenFlow - The Programmable Network Revolution

Over the past few months I have made regular references to OpenFlow. This is an exciting new development that fits in very well with several of the next generation technology developments that we have discussed in some detail over the past few years -- new developments such smart cities and smart societies, the internet of things. Such networks need to operate more on a horizontal level, rather than the usual vertical connection between a computing device and the users.
