SDX Central: Amazon Leads Linux Foundation’s Edge NOS Project

By Community News

The Linux Foundation’s latest open source project DENT targets enterprise edge networking software with support from Amazon, Cumulus Networks, and Mellanox, among other member companies.

The group aims to bring together silicon vendors, original design manufacturers, system integrators, and original equipment manufacturers. Its goal is to build a new standardized network operating system (NOS) for distributed enterprise, campus, and remote and branch office locations with the retail industry as its initial use case.

DENT will use the Linux Kernel, Switchdev, and other Linux-based projects as the basis for the open source NOS, and Amazon will lead the effort to develop the initial seed code.

CNBC: Amazon is joining a project that could upend network chipmakers such as Broadcom

By Community News

Amazon is contributing to a new piece of open-source software that could give it a leg up in its physical stores. The Linux Foundation, a nonprofit organization that maintains the Linux operating system and open-source software, announced the new networking operating system, called Dent, in a statement on Friday.

Dent is a proposed operating system for switches, which are pieces of hardware used to route data around networks, usually within companies or between companies and the internet. The market has traditionally been dominated by big companies such as Broadcom, which provides a lot of the underlying silicon chips, and Cisco, which sells finished assembled product.

CBR: Linux Foundation Aims to Make a DENT in Networking

By Community News

Project will “benefit customers by eliminating vendor lock-in and allow hardware vendors to compete on a level playing field”

The Linux Foundation has a brand new open source baby with some heavyweight godparents: the new project, DENT, aims to create a new, non-proprietary network operating system (OS) that can tackle the issue of networking vendor lock-in head-on.

In particular, DENT’s members intend to build a lightweight, Linux-based networking OS stack suitable for “remote” locations, they said late Friday, using the Linux kernel, Switchdev (a Linux kernel driver model for Ethernet switches) and other Linux projects to allow developers to “treat networking ASICs and silicon like any other hardware.”

Enterprise Networking Planet: Linux Foundation Puts a new DENT in Edge Networking

By Community News

New effort will bring the Linux SwitchDev technology forward to help enable a new generation of lightweight edge switching.

The Linux Foundation has been very active in 2019 across the edge computing landscape and is finishing the year with yet another new effort in the space.

On Dec. 13, the Linux Foundation announced the formation of the DENT project, which aims to develop a disaggregated enterprise network operating system for edge computing. The nascent project already has some big name backers including Amazon, Cumulus Networks, Delta Electronics Inc, Marvell, Mellanox and Wistron NeWeb (WNC)..

The basic idea behind DENT is to deliver a simplified Linux-based network operating system stack that is well suited for edge use cased including retail stores and remote campus locations. A core element of the DENT effort is switchdev, which is an open source in-kernel abstraction model, providing a standardized way to program switch ASICs and speed development time.

Dev Class: Linux Foundation takes aim at NOS segment, opens up DENT

By Community News

The Linux Foundation has unwrapped an effort to develop a close to the edge network operating system with the backing of online retail giant Amazon, amongst others.

The DENT project aims to develop an operating system for disaggregated network switches in campus and remote enterprise applications, with its initial focus, apparently, on retail.

According to the announcement, “DENT hopes to unify and grow the community of Silicon Vendors, Original Design Manufacturers (ODM), System Integrators (SI), Original Equipment Manufacturers (OEM) and end users to create an ecosystem of contributors around a full-featured network operating system.”

DevPro Journal: Linux Foundation’s DENT Project Focuses on Disaggregated Network Switches

By Community News

The Linux Foundation launched DENT to support the creation of network OS for disaggregated network switches in campus, distributed enterprise and remote locations.

Networking solutions, generally, are customized for vertical markets and use cases, and use closed operating systems to enable workloads on a network switch. This, however, locks users into hardware and software from specific vendors. The industry is migrating toward disaggregation, opting for open, standardized network architecture.

DENT Launches To Simplify Enterprise Edge Networking Software

Linux Foundation open ecosystem enables low cost, standardized network solutions for campus and remote offices

San Francisco, Calif., Dec 13, 2019 – The Linux Foundation, the nonprofit organization enabling mass innovation through open source, today announced the launch of DENT, a project to enable the creation of Network OS for Disaggregated Network Switches in campus and remote enterprise locations. Under the Linux Foundation, DENT hopes to unify and grow the community of Silicon Vendors, Original Design Manufacturers (ODM), System Integrators (SI), Original Equipment Manufacturers (OEM) and end users to create an ecosystem of contributors around a full-featured network operating system. The initial use case will focus on the retail industry with premier members including Amazon, Cumulus Networks, Delta Electronics Inc, Marvell, Mellanox, Wistron NeWeb (WNC).

Networking solutions today are customized for each market and each use case, whether telecom, cloud or enterprise data center markets. They use proprietary silicon (ASIC) for packet processing and closed operating systems to enable workloads and applications on a network switch. Disaggregation is the new way for Open Networking and has been well accepted in data centers and telecom infrastructures.  However, in enterprise networking– especially with distributed locations– nothing currently exists for Enterprise Edge properties that fall outside the traditional public cloud as they have very specific requirements to take advantage of disaggregation and the networking stack.

Remote campus locations and retail stores require a simple networking OS stack that is low cost and Linux-based. DENT is an Open Source project that will enable the community to build this solution without complicated abstractions. It uses the Linux Kernel, Switchdev and other Linux based projects to allow developers to treat networking ASICs and silicon like any other hardware. It simplifies abstractions, APIs, drivers and overheads that currently exist in these switches and on other open software.

With new technologies like 5G, Edge, IOT, AI, the next generation of remote buildings, retail stores and enterprises will have a lot of innovative workloads and services close to the applications and users. Having a simple disaggregated Linux/SwitchDev-based switch to power the remote offices will enable an ecosystem of apps that simplifies and standardizes integration across the ecosystem.

“The Linux Foundation will establish a neutral home from the start for DENT – vital for community infrastructure, meetings, events and collaborative discussions,” said Arpit Joshipura, GM of Networking at The Linux Foundation. ”Our goal is to create an open source, open participation technical community to benefit the ecosystem of solution providers and users focused on network operating system, control plane and management plane use cases across a variety of industry solutions.”
