This is the out-of-tree version of [[https://www.bufferbloat.net/projects/codel/wiki/Cake/][CAKE]], the Linux qdisc that combines scheduler and traffic shaper for effective bufferbloat mitigation.
Note that sch_cake is part of the upstream Linux kernel since kernel version 4.19, so this repository exists only as a resource for building the qdisc with older versions of the kernel. If you're already on kernel 4.19 or newer, you can just load CAKE with =tc= and the kernel shipped by your distribution!
