There has been a major change in the landscape of the internet over the past few years with the progressive introduction of the QUIC transport protocol. Here I’d like to look at where we are up to with the deployment of QUIC on the public Internet. But first, a review…
The Internet is, as its name suggests, a network of networks. The glue that holds this together is the inter-domain routing protocol, BGP, or Border Gateway Protocol. BGP is a flooding protocol whose objective is to ensure that all the BGP speakers across the Internet see the same picture of…
I would like to look at the ways in which the operators of the number Resource Public Key Infrastructure (RPKI) have deployed this infrastructure in a way that maximises its available and performance and hardens it against potential service interruptions, or in other words, an examination of the resilience of…
The interdomain routing fabric of the Internet is a somewhat chaotic space. It is not a “centrally managed” space by any means. There is no single entity that is responsible for the Internet’s routing environment. No permissions are required to join, and no notice required to leave. A network doesn’t…
The story of computing and communications over the past eighty years has been a story of quite astounding improvements in the capability, cost and efficiency of computers and communications. If the same efficiency improvements had been made in the automobile industry cars would cost a couple of dollars, would cost…
When the Internet outgrew its academic and research roots and gained some prominence and momentum in the broader telecommunications environment its proponents found themselves to be in opposition to many of the established practices of the international telecommunications arrangements and even in opposition to the principles that lie behind these…
One of the more active areas of activity at the IETF falls under the remit of the DNS Operations Working Group. It’s an operational Working Group rather than a protocol development working group, but nevertheless the DNS is a very rich topic area with much to talk about. There is…
The Internet’s Domain Name System (DNS) is a remarkably simple system. You send queries into this system via a call to your local host’s name resolution library, and you get back answers. If you peek into the DNS system you’ll see exactly the same simplicity: The DNS resolver that receives…
The DNS Operations, Analysis, and Research Center (DNS-OARC) brings together DNS service operators, DNS software implementors, and researchers together to share concerns, information and learn together about the operation and evolution of the DNS. They meet between two to three times a year in a workshops format. The most recent…
I recently attended NANOG 93, in Atlanta in the first week of February (https://nanog.org/events/nanog-93/agenda/). The dominant theme of the presentations this time around was the combination of automation of network command and control and the application of Artificial Intelligence tools to this control function. The interest in AI appears to…
