The Impact of Rising Sea Level on Internet Infrastructure

A recent study predicts that rising sea level might result in as much as 4,067 miles of fiber conduit being under water and 1,101 nodes (data centers, Internet exchanges, cable landing points, etc.) surrounded by water in U. S. coastal cities in 15 years. Paul Barford, professor of computer science at the University of Wisconsin, and his colleagues have been compiling data on the physical Internet and making it available to the research community at the Internet Atlas Web portal since 2011. more

DNA University Launches to Support Domain Name Industry

In pursuit of continued domain name industry success, the Domain Name Association (DNA) is delighted to announce the launch of the next industry resource -- the DNA University. The aim of the DNA University is to establish a dedicated education platform to facilitate the exchange of ideas, best-practice methodologies and continued development of the industry's combined expertise. To this end, the DNA University will offer stakeholders an opportunity to share their experiences, learn from each other and provide a forum to incubate concepts that will advance the domain name industry. more

Are Inter-Satellite Laser Links a Bug or a Feature of ISP Constellations?

I hope each of these companies has someone in charge of thinking about what might go wrong with a single, satellite-based network providing fast, low-cost links anywhere on the global Internet. OneWeb, SpaceX, Telesat and Leosat all aspire to be global Internet service providers using constellations of low-Earth orbit (LEO) satellites. Their success will require still-unproven technological innovation, but there are also political stumbling blocks. more

The Internet as Weapon

One of the most striking and enduring dichotomies in the conceptualization of electronic communication networks is summed up in the phrase "the Internet as weapon." With each passing day, it seems that the strident divergence plays in the press -- the latest being Tim's lament about his "web" vision being somehow perverted. The irony is that the three challenges he identified would have been better met if he had instead pursued a career at the Little Theatre of Geneva and let SGML proceed to be implemented on OSI internets rather than refactoring it as HTML to run on DARPA internets. more

EU “Fair Share” Contagion: Caribbean Telecoms Operators Seek to Deepen Their Monopoly Strangleholds

On Friday, 23rd June, Caribbean telecommunications operators (telcos) held a meeting in Miami to fine tune their strategy to force Big Tech companies to contribute financially to regional telecoms network infrastructure. Hosted by the Caribbean Telecommunications Union (CTU), and taking a similar perspective to the "fair share" proposal currently being debated in the European Union, regional network operators are arguing that over-the-top (OTT) service providers are responsible for 67 percent of the total Internet traffic in the Caribbean, but make no contributions or investments toward local delivery networks. more

To Tax or Not to Tax

Well it is not new that the US has always maintained that the Internet should be a tax free zone as per the US Congress's Tax Freedom Act 1998 which following expiry continued to be reauthorized and its most recent re-authorization (legal speak for extension) was in October 2007 where this has been extended till 2014. It is unclear whether there will be another extension post 2014. There is a moratorium on new taxes on e-commerce, and the taxing of internet access via the Tax Freedom Act. more

North American Broadband Trends

The broadband sector, like the wireless sector, is one of the strongest growth areas of telecommunications. Unlike most OECD countries, where DSL tends to dominate, the majority of subscribers in the US fixed broadband market are cable subscribers. During 2010 the gap continued to widen as the cable companies accounted for 70% of new broadband subscribers compared to the telcos' 30%. Although new broadband networks such as FttH and WiMAX are being widely deployed, broadband competition in each region is still generally limited to one DSL and one cable operator. more

Designing Secure Networks with Cisco Technology, Part 3

In this multipart series I will be presenting some of the leading industry-standard best practices for enterprise network security using Cisco technologies. Each article in the series will cover a different aspect of security technologies and designs and how each can be deployed in the enterprise to provide the best security posture at the lowest possible budgetary and administrative cost. In Part 2 of this series I discussed security risks and vulnerability. In this article we begin to focus on the role Cisco network and security technologies play in ensuring the safety and security of network data. more

GeoTLDs: Diversity is Key

The 2004 new sTLD round brought about a new type of TLD in the form of .asia and .cat. As we always struggle for words to capture their nature, I call them "geoTLDs". Culture, language and ethnicity are also part of geography. Contrary to ccTLDs, geoTLDs do not have a territorial meaning. They are a wonderful addition to the Internet as they provide a way to demonstrate one's commitment to a community that is not defined by borders, yet linked to where the individual chooses to be. ...Will they be? They will, unless we do the wrong thing now. more

Internet Records Retention Bill

A lot of pixels have been spilled lately over an Internet records retention bill recently introduced in both the House and the Senate. The goal is to fight child pornography. That's a worthwhile goal; however, I think these bills will do little to further it. Worse yet, I think that at least two of the provisions of the bill are likely to have bad side effects... more

Prepare for the Worst, But Hope for the Best

A couple of weeks ago, I blogged about the importance of the timeline leading up to the September 2015 deadline for the IANA oversight transition proposal. In that post, I explored the nature of U.S. politics and how it can affect the transition if we, as a community, are not diligent in our efforts to meet that deadline. Since then, the IANA Stewardship Transition Coordination Group (ICG) has held its first meeting and a conference call, resulting in some new information that necessitates an update to that post. more

DNS-Based DDoS: Diverse Options for Attackers

Denial of service attacks have been around since the Internet was commercialized and some of the largest attacks ever launched relied on DNS, making headlines. But every day a barrage of smaller DNS-based attacks take down targets and severely stress the DNS ecosystem. Although DNS servers are not usually the target of attacks they are often disrupted so attention from operation teams is required. There is no indication the problem is going away and attackers continue to innovate. more

JPA Agreement: Will it Change the Problems With the UDRP?

It was rather interesting to read this new agreement between the USDoC and ICANN talking about the mechanisms, methods and procedures necessary to effect the transition of Internet domain name and addressing system (DNS) to the private sector. What was more interesting though was to read in this very agreement the following: "...the Department continues to support the work of ICANN as the coordinator for the technical functions related to the management of the Internet DNS". OK, let's be honest! Technical? more

Three Things Registrars Must Do to Enhance Security

If the rise of phishing has taught us anything, it's that on the Internet, if a digital asset has value, there's somebody out there who wants to steal it. Whether it's a bank account password, a credit card number, a PayPal login, or even a magic sword in an online game, there's a fraudster somewhere trying to misappropriate it for his or her own nefarious purposes. Domain names have always been a target for such criminals. more

Why Understanding Bandwidth is Essential for Improving Subscriber QoE

Measuring and managing subscriber bandwidth can be an easy and cost-efficient way to improve subscriber quality of experience (QoE). In a HFC cable network, bandwidth is shared among users in the same fiber-node. Even though improvements in DOCSIS technology has allowed a substantial increase of bandwidth availability per fiber-node, a few heavy users - as well as new 4K video content - can quickly kill recently-made network investments and leave subscribers with an impression that they are not receiving the quality they deserve. more
