DENT, the Open Source Network Operating System for Distributed Edge, Now Powers AWS Just Walk Out Technology

By Announcements, Blog, News
  • Amazon deploys open source NOS to automate more efficient customer experience with Just Walk Out technology
  • Large-scale deployment by global enterprise commerce leader signals new level of maturity for open source Networking Operating System 
  • Growing ecosystem of members & collaborators across enterprises, silicon vendors, ODMs, OEMs, and System Integrators, demonstrates deployment readiness for disaggregated hardware  

The DENT Project, an open source ecosystem utilizing the Linux Kernel, Switchdev, and other Linux based projects, announced member company Amazon has deployed the DENT operating system (dentOS) as part of its Just Walk Out Technology in third party customer stores worldwide to streamline the customer experience and scale in-store operations. 

The need for retailers to innovate quickly in the pandemic era depends highly on the network to power the in-store components that enable more seamless and touchless experiences, like grab-and-go and electronic shelf labels. The number of devices, such as IP cameras and sensors, needed to enable these features require massive, edge switching and processing. Disaggregated hardware and open-source collaboration is needed to scale and accelerate standardization at the network edge.

DENT provides access to open source based switches at a lower cost and more flexibility compared to proprietary switches with locked ecosystems. DentOS enables the 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.

“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 retail giants to streamline operations. This undertaking is only possible by the power of collaborative open source development.”   

“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”.

“With its cost-effective cloud managed networking products, Quantum Networks has established itself as a reliable partner, especially in emerging markets,” said Mukesh Majithia, Director (Technical), Quantum Networks. “Our collaboration with the DENT community and Sartura is intended to build a roadmap for market-required features. Being able to provide a better service to our customers through the use of Open Source technologies is what sets us apart from traditional vendors at a lower price.”

DENT at ONE Summit

The announcement was shared during the ONE Summit opening keynote address in Seattle, Wash. ONE Summit is the one  industry event that brings together decision makers and implementers for two days of in-depth presentations and interactive conversations around 5G, Access, Edge, Telco, Cloud, Enterprise Networking, and more open source technology developments. 

The DENT community also hosted a collocated workshop to provide details on the NOS’ architecture, use in Distributed Edge scenarios, compatible hardware and how DENT impacts and contributes to the upstream Linux kernel.

The Register: Network operating system Dent 2.0 targets smaller firms

By Community News

The Dent Project has released version 2.0 of its open source network operating system, carving out features designed to make it easier for small or mid-sized enterprises to support edge deployments.

Dent OS is a Linux Foundation project that provides a platform for disaggregated network switches running on white-box hardware, and is based on the Linux kernel and open-source projects such as Switchdev. The first release was codenamed “Arthur”, after Arthur Dent of Hitchhiker’s Guide to the Galaxy, and this latest release was codenamed “Beeblebrox”.

2.0 adds IPv6 and Network Address Translation (NAT) support for scalability and also to support a broader community of enterprise customers. Also new is Power over Ethernet (PoE) control to allow remote switching and monitoring in edge deployments. Another addition is traffic policing measures, such as rate limiting to protect against broadcast storms and help alleviate attacks that attempt to overwhelm key infrastructure.

According to the Dent Project, the new features are intended to allow smaller enterprises to take advantage of disaggregated switches as well as enable use cases beyond the datacenter.
