Given that CircleID is about "Internet Infrastructure" it would be remiss if there wasn't a mention here that October 29, 2014, was the 45th anniversary of the moment when the first message was sent between two ARPAnet computers located at UCLA and the Stanford Research Institute (SRI). That moment was chronicled well this year by Matt Novak writing on Gizmodo's Paleofuture, complete with photos of the original logs and more. more
Can we develop better transport protocols for communication across the Internet? In a world where the "end-to-end" principle is no longer certain and middleboxes are common, which paths through the Internet are actually available to applications? Which transports can be used over these paths? How can applications cooperate with network elements to improve path establishment and discovery? ... These are all questions posed for the Internet Architecture Board's (IAB) Workshop on Stack Evolution in a Middlebox Internet (SEMI). Taking place in Zürich, Switzerland from 26-27 January, 2015. more
On Tuesday, September 9, 2014, you have a great opportunity to watch live a very packed agenda full of great sessions about IPv6, DNSSEC, routing/BGP security and other components of Internet infrastructure streaming out of the UKNOF / ION Belfast event in Belfast, UK. All of the sessions can be seen live. more
The 5th African Peering and Interconnection Forum (AfPIF) gets underway today, August 26, 2014, in Dakar, Senegal, with a packed agenda full of sessions focused on the future of peering and interconnection in Africa. There are sessions targeted at Internet Service Providers (ISPs), Internet Exchange Points (IXPs), infrastructure providers, content creators and policy makers and regulators. The event goes through Thursday, August 28, 2014. more
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
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 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 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 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
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
