With the caveat that I have never worked with any of this hardware, this
is my understanding:

Basically, you can re-use the drop mechanism from RED and use the PIE
algorithm as a (better) way to control the setpoints. This makes it
possible to retrofit it in existing hardware. In fact I believe you can
implement PIE entirely in the (software) control plane on (a lot of)
gear that already knows how to do RED.
