This is linkknot. It's a true link knot. It's messy, and that's
by design. You can view it as a dictionary, as a collection of
write-ups, or as a (very minor) nuisance to web robots.
It has not a whole lot of stuff, and many more links pointing
nowhere as I work on finding the linking closure of it in my spare
time.
In the meantime, I use individual files as a way to reuse basic
explanations of terms.
For now, you might start with delay or QoS entry.
