Most of the excitement over reducing latency under load on edge networks has been focused on the combination of the Flow Queuing + Codel algorithms now in the Linux kernel, called fq_codel. This talk goes into how, why, and where that works, and the sorts of network traffic that can and cannot be optimized. It leverages new studies from cablelabs and others on the prospect of deploying the new AQMs in devices such cable head ends, dslams, cable modems and home gateways.
