Play the recording: Introducing exact-match hardware offload for OVS

Why: Attacks the TCAM orthodoxy in DPU/SmartNIC flow lookup — power consumption and scalability — with an exact-match alternative blending micro/megaflow characteristics.

What: A critique that TCAM-based megaflow offload doesn't scale with ever-growing flow counts, and that TCAM alternatives complicate maintenance and hurt performance as megaflow table counts grow; the proposed solution brings exact-match hardware offload to OVS, demonstrated live.

How / Where applicable: Early-stage, demo-based work from a semiconductor startup; no performance numbers in the abstract. Relevant to anyone modeling DPU lookup-plane power/scalability tradeoffs.
