| Fact | Open Virtual Network | OpenDaylight |
|---|---|---|
| Architecture | OVN translates virtual network configurations into OpenFlow and provides a higher-level abstraction based on logical routers and switches. | Its modular architecture uses YANG models and MD-SAL to connect applications with network hardware through northbound REST APIs and southbound plugins. |
| Purpose | OVN is a system that supports logical network abstraction in virtual machine and container environments. | OpenDaylight is an open source SDN controller for centralized, programmable network control and monitoring. |
| Release support | Standard term releases receive full bug-fix support for one year after initial release; LTS releases receive bug-fix support for two years and another year of critical and security fixes after a new LTS is released. | The downloads page lists Chromium-SR0, Vanadium-SR1, and Titanium-SR3 under supported releases. |
| Runtime | OVN is written in platform-independent C, runs entirely in userspace, and requires no kernel modules to be installed. | The site's setup instructions require Java 21 or later and state that OpenDaylight runs on Linux, macOS, and Windows. |
| Security | OVN’s security process directs vulnerability reports to the ovs-security mailing list for coordinated handling. | The AAA project provides authentication, authorization, accounting, and role-based access control for OpenDaylight northbound interfaces. |
