ovn-local: A new proposed architecture for OVN#

Open vSwitch and OVN 2026 Fall Conference digest Program Core pick 2–4 November 2026

Abstract

Mark Michelson; Ilya Maximets; Dumitru Ceara; Ales Musil, Red Hat, LLC.

  • Why: A panel proposing to re-architect OVN itself — fewer processes, fewer databases — because a decade of feature growth and changed deployment patterns (smaller, more distributed footprints à la ovn-k IC) has left the original centralized architecture a poor fit. Architecture-level signals like this are rare and worth a PM's attention.
  • What: A proposal for a leaner OVN deployment model with a smaller footprint, promising easier deployment and upgrades, faster processing, and reduced memory and disk requirements. (from abstract only)
  • How: Consolidating the process/database structure of OVN (details are the panel's subject); positioned as the direction future OVN releases will take.
  • Where applicable: Every OVN deployment if it lands — this is upstream-project direction-setting by the core maintainers, not an operator-specific design. Watch this one for the following release cycle.
