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»

The Open Internet?

I'm sure we've all heard about "the open Internet." The expression builds upon a rich pedigree of term "open" in various contexts. For example, "open government" is the governing doctrine which holds that citizens have the right to access the documents and proceedings of the government to allow for effective public oversight, a concept that appears to be able to trace its antecedents back to the age of enlightenment in 17th century Europe. 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»

NANOG 61 - Impressions of Some Presentations

The recent NANOG 61 meeting was a pretty typical NANOG meeting, with a plenary stream, some interest group sessions, and an ARIN Public Policy session. The meeting attracted some 898 registered attendees, which was the biggest NANOG to date. No doubt the 70 registrations from Microsoft helped in this number, as the location for NANOG 61 was in Bellevue, Washington State, but even so the interest in NANOG continues to grow... more»

Happy World IPv6 Launchiversary! Two Years Of Remarkable IPv6 Growth

Happy Launchiversary! It's been two years since World IPv6 Launch in 2012, the day many major Internet Service Providers (ISPs), home networking equipment manufacturers, and web companies around the world started permanently enabling IPv6 for their products and services. In the last two years, participation and interest in IPv6 has only grown. Today nearly 250 network operators around the world are participating in World IPv6 Launch measurements, and we continue to see increased IPv6 deployment by network operators, websites, and home router vendors. more»

Telegeography's Submarine Cable Map Now Lets You Link to Specific Cables or Landing Points

Want to easily show people where a specific submarine cable goes? Or what cables terminate in a particular location? Last year I wrote about Telegeography's cool interactive submarine cable map and how useful it is to understand the submarine cable side of Internet infrastructure. In that article I mentioned how great it would be if you could get a link for a particular cable or location that you could pass along to other people. more»

Human Network, Human Challenges

It has now been about eight months since I joined the Internet Society as the Director of Deployment & Operationalization and I still get asked on a fairly regular basis "what do you do?" Well, with ISOC's Chief Internet Technology Officer Leslie Daigle's recent departure, and with my time here having exceeded both my first 120 days and my first 6 months, this seems like the right moment to reflect on my brief tenure here so far and perhaps pontificate a bit on where we're going - and why. more»

Summary Report Now Posted of W3C/IAB "Strengthening The Internet (STRINT)" Workshop

Given that I've written here about the original call for papers for the W3C/IAB "Strengthening The Internet Against Pervasive Monitoring (STRINT)" Workshop and then subsequently that the STRINT submitted papers were publicly available, I feel compelled to close the loop and note that a report about the STRINT workshop has been publicly published as an Internet-draft. more»

The Importance of IP Resource Planning in Government ICT Strategic Plans

It seems everywhere I turn, there's someone throwing around statistics for how the Internet and broadband will drive economic growth, create jobs, end world hunger and bring world peace (ok, maybe not the later). Sure enough, government officials are buying into that rhetoric and extending it in initiatives like national broadband strategies, cybercrime and cybersecurity plans as well as e-governance strategies. more»
