The Longevity of the Three-Napkin Protocol

It is not often I go out to my driveway to pick up the Washington Post -- yes, I still enjoy reading a real physical paper, perhaps a sign of age -- and the headline is NOT about how the (insert DC sports team here) lost last night but is instead is about an IT technology. That technology is the Border Gateway Protocol (BGP), a major Internet protocol that has been around for more than a quarter century, before the Internet was commercialized and before most people even knew what the Internet was. more

Digital Economy + Sharing Economy = Networked Economy

A great deal of discussion is taking place about topics such as the digital economy, sharing economy and networked economy. Obviously these are concepts rather than being well-defined, but they are being used by the various players in the market to argue for or against certain developments. For example, in some of the broadband debates around the world, the digital economy is the key reason why national broadband infrastructure gets developed. more

Painting Ourselves Into a Corner with Path MTU Discovery

In Tony Li's article on path MTU discovery we see this text: "The next attempt to solve the MTU problem has been Packetization Layer Path MTU Discovery (PLPMTUD). Rather than depending on ICMP messaging, in this approach, the transport layer depends on packet loss to determine that the packet was too big for the network. Heuristics are used to differentiate between MTU problems and congestion. Obviously, this technique is only practical for protocols where the source can determine that there has been packet loss. Unidirectional, unacknowledged transfers, typically using UDP, would not be able to use this mechanism. To date, PLPMTUD hasn't demonstrated a significant improvement in the situation." Tony's article is (as usual) quite readable and useful, but my specific concern here is DNS... more

MIT 2010 Spam Conference Starts Tomorrow…

In January we presented the glorious history of the MIT spam conference, today we present the schedule for the first day. Opening session will be from this author, Garth Buren with a topic entitled The Internet Doomsday Book, with details be released the same day as the presentation. Followed by Dr. Robert Bruen with a review of activities since the last MIT spam conference... more

Malaysia Reverses Decision on Controversial DNS Redirection Policy

The Malaysian government has backtracked on its recent decision to require Internet Service Providers (ISPs) to redirect Domain Name System (DNS) traffic away from third-party servers like Google Public DNS and Cloudflare. more

“Internet Drivers License” - A Short History Lesson

The press, the blogosphere, CircleID - everybody has been discussing Craig Mundie's comment on the need for an "Internet Driver's License". Most of the reaction has been from privacy advocates fearing that this is simply another way to kill anonymity on the Internet. Oh well... that's the usual set of reactions. Now... the fun part is, a driver's license also shows that you have the competence to drive... more

How a DNS Proxy Service Can Reduce the Risk of VoIP Service Downtime

Consumers are embracing VoIP services now more than ever as they get used to calling over Internet application services such as Skype, Facetime, and Google Hangouts. Market Research Store predict that the global value of the VoIP services market is expected to reach above USD140 billion in 2021, representing a compound annual growth rate of above 9.1% between 2016 and 2021. more

The Satellite Broadband is Heating Up

There is a lot of news recently about low-orbit satellite broadband. There is recent news concerning the three primary companies that will be vying in the space. First is Jeff Bezos Project Kuiper, which is still likely to get a brand name at some point. Project Kuiper has contracted with United Launch Alliance, a joint Boeing-Lockheed Martin venture, for the first nine broadband rocket launches. more

A Look Back at the Pandemic and What Was Missed in the ISPs’ Broadband Performance Reports

I was looking back at industry reporting a year ago after the impact of the pandemic first hit our broadband networks. Almost every big ISP issued press releases talking about how well it had weathered the pandemic and bragged about the resiliency of its networks. It turns out that these ISP press releases largely missed the point. They are right that their networks didn't crash, but once we understood the nature of the changes in broadband traffic due to the pandemic, that wasn't a big surprise. more

Russia Appears to Have Begun Providing an Internet Connection to North Korea

Network experts monitoring North Korea have detected activation of a new internet path out of North Korea. Doug Madory, Director of Internet Analysis at Dyn, along with North Korea expert Martyn Williams, report that at 09:07:51 UTC on 1 October 2017, the country's single internet provider, Star JV (AS131269), gained a new connection to the global internet through Russian fixed-line provider Transtelecom (AS20485), often referred to as TTK. more

Guowang Finally Launches Ten Large Production Satellites

In April 2020, The Chinese State Council's executive meeting declared information technology, including satellite Internet, an important part of the "new technology," and in October, China applied for Guowang, a 12,992-satellite Internet service constellation. Subsequently, a few Guowang test satellites were launched, and two other large Chinese constellations were announced, and one, Thousand Sails, already has 54 satellites in orbit. (Thousand Sails launches have had problems with debris and orbit raising, which attests to the immaturity of the Chinese space industry). Finally, Guowang has launched its first production satellites. more

The IETF’s *Other* Diversity Challenge

The Internet Engineering Task Force (IETF) is the standards body for the Internet. It is the organization that publishes and maintains the standards describing the Internet Protocol (IP -- versions 4 and 6), and all directly related and supporting protocols, such as TCP, UDP, DNS (and DNSSEC), BGP, DHCP, NDP, the list goes on, and on... But how do they do that? How does the IETF produce documents, and ensure that they are high quality, relevant, and influential? more

The End of HFC and FttN Networks is Approaching

In the global telecoms industry, it looks as though 2013 will be remembered as the year when construction of new greenfield HFC networks came to a halt. Of course, there will still be upgrades to existing networks but the cost of fibre deployment -- linked to its much lower operational cost -- is now convincing cablecos and telcos alike to build new fibre networks wherever possible. This is not necessarily directly driven by customer demand, but by network costs and network efficiencies. more

Russia and China Propose UN General Assembly Resolution on “Information Security”

On September 12 China, the Russian Federation, Tajikistan and Uzbekistan released a Resolution for the UN General Assembly entitled "International code of conduct for information security." The resolution proposes a voluntary 12 point code of conduct based on "the need to prevent the potential use of information and communication technologies for purposes that are inconsistent with the objectives of maintaining international stability and security and may adversely affect the integrity of the infrastructure within States..." more

Net Neutrality and the Obama Stimulus Package

As long as US telecom is duopoly dominated, a neutral Internet is endangered if not impossible; regulation of this kind of concentrated power is necessary but is unlikely to be sufficient. The solution, IMHO, is to dilute the power of the duopoly so that consumers can buy whatever kind of Internet access they want. Countries like the UK with a competitive ISP market do not seem to have net neutrality problems nor require net neutrality regulation and have better Internet access than we do at lower prices. more
