Explore advanced bandwidth management techniques using eBPF in this 31-minute conference talk from KubeCon + CloudNativeCon North America 2022. Delve into the challenges of unbounded network communication in Kubernetes clusters and discover how eBPF can be leveraged for flexible, efficient, and scalable rate limiting and bandwidth management on a per-Pod basis. Learn about the scalability limits of token bucket filters, the advantages of Earliest Departure Time (EDT) combined with eBPF, and how TCP congestion control with BBR can be applied to Pods for improved application latency and throughput. Gain insights into enforcing bandwidth limits at the egress point and considerations for ingress enforcement, equipping you with valuable knowledge to optimize network performance in cloud-native environments.
