Extremely Fast and Efficient NFV with Unikraft
summary
Ports DPDK to Unikraft and delivers a portable build layer called libuk_dpdk plus adapters like uk_ring to translate netbufs↔mbufs; implements uk_pmd drivers and a polling-mode flow. Throughput matches Linux VM for most packet sizes, with RX at ~11–11.5M pps vs Linux ~13M pps for 64B packets and a KV workload at ~6M pps on one core. Resource wins: 1 GB RAM vs 6 GB, 87 ms boot vs 12 s, and a 1.4 MB image vs 2.5 GB.
