‘The Global Village’ Idiot

I recall from some years back, when we were debating in Australia some national Internet censorship proposal de jour, that if the Internet represented a new Global Village then Australia was trying very hard to position itself as the Global Village Idiot. And the current situation with Australia's new Data Retention laws may well support a case for reviving that sentiment. more

EU’s Cyber Security Agency Identifying Five Areas as Critical IT Security

The EU's 'cyber security' Agency ENISA (The European Network and Information Security Agency) has launched a new report concluding that the EU should focus its future IT security research on five areas: cloud computing, real-time detection and diagnosis systems, future wireless networks, sensor networks, and supply chain integrity. more

Steering Website Traffic with Managed DNS vs. IP Anycast

I recently read an interesting post on LinkedIn Engineering's blog entitled "TCP over IP Anycast -- Pipe dream or Reality?" The authors describe a project to optimize the performance of www.linkedin.com. The web site is served from multiple web server instances located in LinkedIn's POPs all over the world. Previously LinkedIn used DNS geomapping exclusively to route its users to the best web server instance, but the post describes how they tried using BGP routing instead. 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

Microsoft Disrupts the Zeus Infrastructure

Over the weekend and this morning, Microsoft, working in conjunction with others, issued civil lawsuits to sinkhole numerous domains associated with the Zeus botnet. When I say "botnet", I use the term loosely because Zeus is not a botnet in the sense that Rustock or Waledac is (or was). Rather, Zeus is a tool kit that online criminals can buy that lets them create phishing pages, perform fast fluxing, host drive-by downloads in addition to spamming. It's more like infrastructure than a botnet, although it does have a large botnet under its control. more

Measurement Results from World IPv6 Launch

As announced on RIPE Labs we monitored the behaviour of a number of networks that participated in the World IPv6 Launch on 6 June 2012. For that, we looked at the full list of participating organisations as shown on the ISOC website and chose 50 websites from that list. We looked at 'interesting' sites and at geographic distribution. We also tried to find a good mix of networks that had IPv6 switched on already and those that didn't have IPv6 deployed at the time they registered on the ISOC web site. more

The Netizen’s Guide to Reboot the Root (Part II)

The first part of this series explained how Amendment 35 to the NTIA-Verisign cooperative agreement is highly offensive to the public interest. But the reasons for saving the Internet are more fundamental to Western interests than a bad deal made under highly questionable circumstances. One of the world's foremost experts on conducting censorship at scale, the Chinese Communist Party's experience with the Great Firewall... more

The Mobile Internet

It has been observed that the most profound technologies are those that disappear (Mark Weiser, 1991). They weave themselves into the fabric of everyday life until they are indistinguishable from it, and are notable only by their absence. The feat of reticulating clean potable water into every house, so that it is constantly accessible at the turn of a tap, is a great example of the outcome of large scale civil engineering projects, combining with metallurgy, hydrology, chemistry and physics. But we never notice it until it is no longer there. more

OARC-39: Notes on the Recent DNS Operations, Analysis, and Research Centre Workshop

OARC held its fall meeting in Belgrade on October 22 and 23. Here are my impressions of some of the presentations from that meeting... UI, UX, and the Registry/Registrar Landscape - One of the major reforms introduced by ICANN in the world of DNS name management was the separation of registry and registrar functions. The intent was to introduce competition into the landscape by allowing multiple registries to enter names into a common registry. more

Notes from NANOG 89: Trust and Network Infrastructure

Trust is such a difficult concept in any context, and certainly, computer networks are no exception. How can you be assured that your network infrastructure is running on authentic platforms, both hardware and software and its operation has not been compromised in any way? more

The Sustained Potential and Impact of Mobile & Wireless Technologies Access for Emerging Economies

I believe Mobile Information and Communications Technologies (ICTs) are and very well remain powerful and best-suited technologies that will help provide connectivity and digital access in a much faster and cheaper way for developing countries of the globe. Thus, they are to be leveraged within their most strategic and profitable functional or usage contexts. Mobile access technologies along with relevant innovations have formed a powerful springboard for the Internet to be significantly accelerated in terms of access, usage and penetration. more

Old Cloud vs. New Cloud

Images of clouds have been used when discussing networks for quite some time. When traditional telecoms companies were selling point-to-point circuits a drawing of a cloud was sometimes used. The cloud symbol helped indicate the provider?s domain of responsibility, effectively hid the internal complexity of the network and focused on the end user. This was all fine when the product offered was an end-to-end circuit. more

The ISP Industry: Concentrated or Diverse?

In August 2010, we looked at the growth in RIPE NCC membership and concluded that the number of new RIPE NCC members is still growing at an amazing pace, even during the recent economic downturn... This time we are looking at the different sizes of RIPE NCC members over time. It is often claimed that there is massive consolidation happening in the ISP community, especially in times of economic difficulties like in the early 2000s and now. We were curious to find out if this is really the case. more

Treating Different Types of Communications Differently

A friend who read my Creating Sustainable Network Neutrality paper wrote to say, "Help me understand what is so bad about treating different types of communications differently." That's a really good question! If you want to offer vertically integrated services on special purpose networks, such as video entertainment or pager service or telephony, I do not have a problem with that, provided you don't use your market power to impede Internet applications that offer competing services... more

Your AI Strategy Canvas: Part 1

As the final project of my UC Berkeley School of Information course in Artificial Intelligence strategies, we had to submit an AI strategy canvas. Today, I will attempt to share important aspects of the canvas, so you and your team may have a template to work from and consider. Let's begin. We will look at both a strategy and operations perspective both internally and externally. Part one will include Internal and Operational Strategies, while Part II will examine external processes, threats, and procedures. more
