100Gbit/s Clusters with Cilium - Building Tomorrow's Networking Data Plane

Explore the future of networking in this conference talk on building 100Gbit/s clusters with Cilium. Delve into the transition from IPv4-only clusters to IPv6-only deployments, unlocking new possibilities in IPAM flexibility and cluster scalability. Discover recent advancements in Cilium's networking data plane, enabling a low-latency architecture suitable for "BIG TCP"-based workloads requiring IPv6 for 100Gbit/s transfers and beyond. Learn about a new veth driver replacement developed specifically for the kernel in the context of Cilium, achieving host networking performance characteristics for Pods. Gain insights into the resulting eBPF forwarding architecture, which bypasses unnecessary parts of the stack to drastically improve networking performance.
