summary
Claims a terabit-scale application-insight pipeline combining fast packet processing with ML to classify apps and infer video resolution and user experience from flow telemetry. Early proof uses P4 programmable switches to stream per-flow time-series at line rate (6.4 Tb/s) and suppress 80% of packets so CPU handles 20%, delivering a 400 Gb/s analytics box in 3U (two servers). Later moves to eBPF-based CNFs and Cilium/Hubble/Tetragon yield cloud‑native deployability and software speeds of ~80–90 Gb/s per 24 cores and up to ~200 Gb/s on one server.
