DENT Member Spotlight: Marvell

By Blog

Kishore Atreya,
Software Product Line Manager,
Marvell

At DENT, we are kicking off a new Member Spotlight blog series to highlight our community members and organizations. Our first QA is with Kishore Atreya, Software Product Line Manager at Marvell. Intersted in being spotlighted? Send an email request to PR@dent.dev

Can you tell us a little about your organization?

(Kishore): Marvell is a leading provider of data infrastructure semiconductor solutions which includes a comprehensive networking portfolio under which the Marvell Prestera® Ethernet switch product family resides. We have been building switches for well over 20 years with millions of devices in production and deployed worldwide for a wide variety of use cases including enterprise, retail edge, carrier, data center, and SMB. In addition to our silicon portfolio, we work with and maintain a healthy software ecosystem with support of  SDKs, NOSs and HALs.

Why is your organization adopting an open-source approach?

(Kishore): We are strong believers in enabling customers to control their own destiny. Open source is a great vehicle for this. The modern network operating system is transitioning to a commoditized set of features based on standards. An open source approach democratizes the data plane and control planes of a network thereby providing operators choice. Enabling users to build their own features and applications to run on top of a standard NOS allows the ultimate flexibility in deployment and facilitates advanced use cases of networking equipment such as data in-flight machine learning.

Why did you join DENT and what sort of impact do you think DENT has on the edge, networking, and IoT industries?

(Kishore): We joined DENT because we are strong believers in its mission and because of the fact that it is based off of Linux. Linux provides operators the ability to manage switches like servers which is advantageous for deployments that are spread out over multiple branches, such as that of the retail edge. Additionally, since DENT is Linux-based, it’s extremely easy for users to add their own applications on top of the switch OS. These applications can take advantage of on-switch CPU resources to reduce latency in environments where there are many endpoints such as in the emerging edge applications scenario. Data can be aggregated in the network and pushed out, minimizing the amount of northbound traffic going to a data center.

Additionally, we  saw that there is a gap in the market with respect to NOS disaggregation for enterprise and edge networks. DENT fills this gap quite nicely with its targeted approach to the edge.

What do you see as the top benefits of being part of the DENT community?

(Kishore): Being a part of the DENT community provides silicon vendors unparalleled access to emerging trends in enterprise, edge, and networking, giving us insight to challenges these industries are facing. Working with the DENT community, we can put together unique solutions to help address the specific requirements of what we call the borderless enterprise. As mobility and cloud applications extend the boundaries of the traditional campus environment, deployments at the access and edge will continue to grow. We are committed to helping bring innovative solutions for automated and personalized experiences within the borderless enterprise across the smart edge and retail networking.

What sort of contributions has your team made to the community, ecosystem through DENT participation?

(Kishore): Our team is an active participant in the community. We are working on the Technical Steering Committee to drive the DENT roadmap and are also contributors to test cases and switchdev drivers. The Arthur release, announced by DENT in December, is running on multiple 1G and 10G platform deployments incorporating Marvell’s Prestera Ethernet switches in production.

What do you think sets DENT apart from other industry alliances?

(Kishore): The open governance model of DENT is what sets DENT apart from other alliances. Every member has a seat at the table and decisions are made for the betterment of the community.

How will DENT help your business?

(Kishore): DENT helps our business by plugging a hole in the larger disaggregated NOS market for enterprise and edge use cases. Having a NOS supported by a rich community allows our sales and channel partners to put together proposals addressing customers who need a NOS for enterprise or edge use cases, but do not have the resources to do one on their own. We are able to train our channels to promote DENT via the strength of its community which includes system integrators, ODMs, silicon vendors, and end customers.

What advice would you give to someone considering joining DENT?

(Kishore): Do it — the more the merrier! If you have a problem that needs solving for emerging edge or enterprise networking use cases, come be a part of the only community NOS that is directly targeting that space. DENT is not for one user—it is for all and every voice is recognized at the table.

DENT Introduces Industry’s First End-to-End Networking Stack Designed for the Modern Distributed Enterprise Edge and Powered by Linux

By Announcements

· Dent issues “Arthur”, its First Code Release that Delivers an Open, Simplified Networking Operating System for next-generation retail and campus networks

· Linux Foundation announces inaugural Dent general members committed to delivering enterprise-grade, disaggregated networks through an open ecosystem

San Francisco, December 17, 2020The Linux Foundation, the nonprofit organization enabling mass innovation through open source, today announced Arthur — the first code release of Dent, a project to enable the creation of a Network Operating System (NOS) for Disaggregated Network Switches in campus and remote enterprise locations. Since its December 2019 launch, several companies have joined DENT as general members, including Innovium, Arcadyan, Aviz Networks, and Alpha Networks who are joined by Dent premier members Amazon, Delta Electronics Inc, Marvell, NVIDIA, Edgecore Networks, and Wistron NeWeb (WNC).

The Arthur release – aptly named after Arthur Dent, the protagonist character of Hitchhiker’s Guide to the Galaxy– uses the recently released Linux 5.6 Kernel and leverages SwitchDev to simplify integrations, eliminate complex abstractions and SDK change management, and support existing Linux tool chains. In addition to providing the industry’s widest range of hardware options, the Arthur release includes over 25 key features to enable enterprise infrastructure teams to safely transition to disaggregated networks.

“With the Arthur release, we’re witnessing the makings of an open network operating system, control plane and management plane that will transform how enterprises address their distributed edge challenges,” said Arpit Joshipura, general manager, Networking, Edge and IoT, at The Linux Foundation. “The DENT community has grown quickly and executed on this first major code release at a time when the entire industry is rethinking the future of retail and campus environments.”

The networking industry is moving away from customized, proprietary solutions for telecom, cloud and enterprise data center markets in favor of open standards. However, these open advancements have failed to meet the specific needs of distributed enterprise edge networking, such as a simplified networking OS stack that is low cost and Linux-based. DENT enables an open 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. This simple disaggregated Linux/SwitchDev-based switch ultimately simplifies integration across the ecosystem and encourages application developers to adopt this new standard.

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.”
