Imagine enjoying a peaceful and quiet Kubernetes evening, when those miscreants show up and wreck the network latency and throughput on your shared nodes! In order to safeguard the fair network resource distribution, Cilium has introduced the Bandwidth Manager feature: an egress bandwidth rate-limiting mechanism to keep those noisy neighbours in check. This short talk will give an overview of how the Bandwidth Manager does its job by leveraging the Fair Queue (FQ) packet scheduler and eBPF-based Earliest Departure Time (EDT) algorithm. Additionally, the attendees will learn about the performance implications of enabling this feature and potential pitfalls in Cloud environments.
