Running High-performance User-space Packet Processing Apps in Kubernetes
Talkat KubeCon + CloudNativeCon North America 2019 · on Thursday, 2019-11-21· at 14:25· Room 11AB - San Diego Convention Center, Upper Level·
summary
Shows how to run real DPDK VNFs on Kubernetes using DPDK testpmd + pktgen and SR‑IOV passthrough, with Multus, an SR‑IOV device plugin and an SR‑IOV Network Operator to automate config. Cluster uses CPU Manager, Topology Manager + CPU Manager alignment and hugepages to guarantee locality and performance. Demo runs on dual‑socket Intel hardware, achieves full line‑rate in the lab with zero packet loss for the test flow, and documents manifests and operator workflow.
