My name is Toke Høiland-Jørgensen, and I’m a PhD student at Karlstad University, Sweden. I am originally from Denmark, but moved to Sweden to pursue my PhD studies, because Karlstad University has a computer science department with a lot of cool networking people. My research interests are centred around networking at the edge of the internet, in particular on reducing unnecessary latency. I have been involved in the bufferbloat project for several years, and I am a contributor to the Linux kernel.
A big part of what I do is based on doing measurements, which I prefer to do on real hardware. Since this is often tedious work, I started automating it, and those efforts over time grew to become the Flent testing tool which is now widely used in the bufferbloat community. I also occasionally write other code, most of which I collect on Github.
When I’m not sitting in front of a computer, I like reading books, playing music (I’m a fairly mediocre drummer), and going rock climbing. And lots of other stuff that is too unspecific or boring to mention here.
Hopefully this list will grow over time. Roughly reverse chronological order.
