Simply put, RED is a very old algorithm, one of the first viable AQM algorithms. However, it proved to be so difficult to configure properly that almost nobody uses it, even though many carrier grade routers implement it.

Codel not only performs better than an ideally configured RED, but is far easier to configure. This makes it much more deployable.
