OVN
OVN, short for Open Virtual Network, is an open-source project that provides a programmable, policy-driven virtual networking layer for cloud environments. Built on the Open vSwitch (OVS) ecosystem, OVN aims to decouple the control plane from the data plane, enabling scalable, multi-tenant networks for virtual machines and container workloads. It defines logical network abstractions that can span multiple hosts and can be managed independently of the underlying physical network.
The OVN architecture centers on a two-database model and a modular control plane. The Northbound database stores
Key features of OVN include logical switching, logical routing (including distributed routing for scalability), NAT, ACL-based
OVN is maintained as an open-source project within the Open vSwitch ecosystem and is used in various
