summary

Disaggregates stateful network functions off hosts into shared appliances that combine general‑purpose ARM cores with match‑processing ASICs, implemented as a 3U server with 6 DPUs that expose a floating NIC. Shows production and lab results: full 100 Gbps line rate, >50M PPS, 64M concurrent connections and bursts of 1.75M connections/sec in open loop, plus lower TCP setup latency than vSwitches and a primary/secondary replication scheme that survives card failures with brief packet loss.
