Live Today: IXPs and the Relationship Between Geography and Network Topology

Today at 5:10pm EDT the IETF 90 Technical Plenary will be streamed live out of Toronto, Canada... After some initial reports, the technical focus will be on "Network topology and geography." The session will be recorded for later viewing. The slides are online and from what I can see it should be a very interesting talk for those of interested in the underlying infrastructure of the Internet. more»

AXIS - The Fulcrum of Africa's Internet Success

The Internet Society (ISOC) has been working with the African Union (AU) to facilitate the African Internet Exchange System (AXIS). This AXIS project funded by the EU-Africa Infrastructure Trust Fund and the Government of Luxembourg will help keep Internet traffic in Africa internal to the continent and avoid expensive international transit costs and delay latency in routing Internet traffic through other continents. more»

Connectivity Policy and the Open Internet

The goal of public policy for connectivity should be to assure access to our common facilities as a public good by adopting sustainable business models that don't put owners and users at odds with each other. Such balances are typically difficult to achieve which is what makes connectivity so unusual - we can achieve both once we fund the facilities as a public good apart from the particular applications such as telephone calls and cable content. 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»

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»

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»

FCC's "Commercial Reasonableness" Standard Already a Dismal Failure

T-Mobile filed a petition today making it clear that the FCC's commercial reasonableness standard is a failure. Anyone following net neutrality knows that the FCC is proposing to authorize discrimination and pay-for-priority deals known as fast lanes. The FCC is claiming we need not worry, however, because the FCC can make sure that entrepreneurs and users face only "commercially reasonable" discrimination. more»

The Demand and Supply Imbalance in Telecoms

You can't open a newspaper today, listen to the radio, or watch TV without hearing about the enormous explosion in the use of telecommunications technology - be it fixed or mobile broadband, the internet, social media, smartphones, tablets, wearables, IoT, cloud computing, the list is endless... Yet, at the same time, many telcos and ISPs are struggling to maintain their profitability. This defies economic logic. more»

The Rotten Roots - Summary of Issues and Sources on Net Neutrality

The timeline of the Net Neutrality issue has been detailed here. And quoting from Vox: 'Wheeler said that peering is "an issue that we are investigating, it's an issue we are very interested in, but it's not the issue here today."' more»
