DentOS 3.0 Unveiled Open Source NOS Powering Distributed Enterprise Edge Brings Network Management, Scalability, and Security via New Rapid Release Cycle

The DENT project, an open source network operating system utilizing the Linux Kernel, Switchdev, and other Linux based projects,announced the launch of DentOS 3.0, code-named “Cynthia,” a cutting-edge network operating system (NOS) that’s now moved to a more rapid release cycle.  This innovative operating system provides a flexible and customizable platform for network administrators to manage their networks, while also leveraging the power of open source technologies.

DENT provides access to open source- based switches at a lower cost and with more flexibility compared to proprietary switches with locked ecosystems. Network wiring closets in many facilities–including retail stores, warehousing, remote locations, enterprises, and small and mid-sized businesses–are often small, requiring a compact solution for network management. Additionally, staff expertise may be limited, and branch-office switches from leading suppliers can require costly contracts. DENT can be easily deployed on white-box hardware in small spaces, providing an efficient and cost-effective solution for network management. As a result, DENT deployment can significantly enhance network management in a wide range of environments, providing greater efficiency, reliability, and scalability.

DENT in Deployment

DentOS enables Amazon’s Just Walk Out Technology to connect and manage thousands of devices like cameras, sensors, entry and exit gates, and access points on the network edge. For more information, please see this presentation from ONE Summit 2022, as well as content from the latest DENT Mini-Summit, co-located at ONE Summit.

“We are pleased to leverage the DENT open-source platforms to power networking infrastructure to enable customers to skip check-out lines with our Just Walk Out Technology,” said Jason Long, head of Networking for Amazon Physical Retail Technology and chairman of the DENT Board. “DENT enabled us to reduce our networking costs by giving us access to open-source switches that allowed Amazon to efficiently deploy new hardware and software whenever we need instead of waiting for a bug fix from a third-party vendor”.

“Adoption and deployment by the world’s largest e-commerce leader with its Just Walk Out Technology is a shining example of the power of open source,” said Arpit Joshipura, general manager, Networking, Edge and IoT, the Linux Foundation. “In just three years, the DENT community created a working platform for disaggregated networks to power multiple device locations at the edge, now used by top retailers to streamline operations. This undertaking is only possible by the power of collaborative open source development.”
