dentOS is a SwitchDev based NOS built on top of Open Network Linux

As a Linux Foundation project, DENT utilizes the Linux Kernel, Switchdev, and other Linux based projects as the basis for building a new standardized network operating system without abstractions or overhead. All underlying infrastructure — including ASIC and Silicon for networking and datapath — is treated equally; while existing abstractions, APIs, drivers, low-level overhead, and other open software are simplified. DENT unites silicon vendors, ODMs, SIs, OEMs, and end users across all verticals to enable the transition to disaggregated networks.
