summary

Shows concrete OpenStack + DPDK tuning: CPU pinning, hugepages, PMD binding, NIC offloads and affinity changes; host and VM flavors set for pure isolation and large page memory. Uses OVS‑DPDK and VPP for user‑space datapath and AF_XDP sockets to mix CNF and kernel‑stack apps. Measured results: small‑packet throughput more than doubles vs kernel, and layer‑2 forwarding holds <30 µs for 512‑byte frames in their tests.
