Over the past few months I’ve had the opportunity at various network operator meetings to talk about BGP routing security and also highlight a measurement page we’ve set up that measures the extent to which Route Origin Validation (RoV) is actually “protecting” users (https://stats.labs.apnic.net/rpki). By this I mean we’re measuring…
When a service is constructed using diverse components, then the way in which service revenues are distributed to the various suppliers of the components of the service can follow a number of quite distinct models. There are various forms of revenue redistribution models where the revenue per transaction is distributed…
The DNS is a remarkably simple system. You send it queries and you get back answers. Within the system you see exactly the same simplicity: The DNS resolver that receives your query may not know the answer, so it, in turn, will send queries deeper into the system and collects…

APAN (Asia Pacific Advanced Network) brings together national research and education networks in the Asia Pacific region. APAN holds meetings twice a year to talk about current activities in the regional NREN sector. I was invited to be on a panel at APAN 50 on the subject of Cyber Governance,…

It has gone through the Full Monty of the current IETF standardization process, including the steps of document review for Working Group adoption, further cycles…
Much the Internet operations and research world has gone virtual for 2020. Meetings continue to take place and while the level of interaction in these meetings is different, many of these meetings continue to engender useful conversations. In my case I’m interested in the infrastructure that binds the network together…
These days it seems that whenever we start to talk about the DNS the conversation immediately swings around to the subject of DNS over HTTPS (DoH) and the various implications of this technology in terms of changes in the way the DNS is used. It’s true that DoH is a…
How well are we doing with the adoption of Route Origin Validation in the Inter-Domain routing space? There have been many workshops and training sessions and much in the way of counting the generation of RPKI certificates and Route Origin Attestations in recent months. The data published by the US…
It’s now the season of virtual workshops, and without the overhead of time spent travelling to these events it’s been possible to participate in a number of these events all over the Internet in the space of a few days. This week I participated in a workshop on measurement of…
