DENT is a special-purpose Linux
distribution aimed at router deployments; “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“. Version
2.0 has been released:

DENT 2.0 adds secure scaling with Internet Protocol version 6
(IPv6) and Network Address Translation (NAT) to support a broader
community of enterprise customers. It also adds Power over Ethernet
(PoE) control to allow remote switching, monitoring, and shutting
down. Connectivity of IoT, Point of Sale (POS), and other devices
is highly valuable to retail storefronts, early adopters of
DENT. DENT 2.0 also adds traffic policing, helping mitigate attack
situations that overload the CPU.
