DENT 2.0, a secure and scalable open-source network operating system for small and medium-sized businesses, available now


SAN FRANCISCO, March 8, 2022 /PRNewswire/ — The DENT project, an open-source network operating system using the Linux kernel, Switchdev and other Linux-based projects, today announced that DENT 2.0 is available for immediate download. The “Beeblebrox” release adds key features used by distributed enterprises in retail and remote installations, providing a secure and scalable Linux-based network operating system (NOS) for disaggregated switches adaptable to edge deployment. DENT provides a smaller, lighter NOS for use on small remote edges of corporate networks.

DENT 2.0 adds secure scaling with Internet Protocol version 6 (IPv6) and Network Address Translation (NAT) to support a wider community of enterprise customers. It also adds Power over Ethernet (PoE) control to enable remote switching, monitoring and shutdown. The connectivity of IoT, point of sale (POS) and other devices is very valuable for retail storefronts, early adopters of DENT. DENT 2.0 also adds traffic policing, helping to mitigate attack situations that overload the CPU.

“DENT has made great strides over the past year and with its Edge and native Linux approach, with a rich feature set for distributed businesses such as retail or remote facilities. DENT continues to grow in new use cases and welcomes community feedback with an open technical community, under the Linux Foundation,” said Arpit JoshipuraGM of Networking & Edge at the Linux Foundation.

Core features of DENT 2.0 to enable secure and scalable development

  • Secure scaling with IPv6 and NAT to appeal to a wider community of SMB customers
  • PoE control to enable remote switching, monitoring and shutdown
  • Rate limiting to protect against broadcast storms, creating a stronger OS under erroneous BUM (Broadcast, Unicast, Multicast) traffic

DENT goes beyond the data center to enable enterprises to move to disaggregated network switches and the use cases available with distributed enterprise and edge networking. The open source NOS offers a key technology lever in retail, an industry that is at the forefront of innovation in digital transformation. Amazon public showcase of DENT hardware at re:Invent in November 2021 reached over 20,000 attendees.

“This new version of DENT 2.0 adds critical updates focused on the needs of small businesses. This was DENT’s goal from the start, and I want to thank our members and the wider community for this broad effort. and concerted effort to significantly advance DENT,” mentioned steven noble, Chairman of the DENT technical steering committee. “It’s not easy to build a flexible and accessible network operating system, and that’s why I’m proud of all the effort and coordination of so many talented people. If you’re looking for a network operating system disaggregated open source, now is the time to look at DENT.”

Retail stores, warehouses, remote sites, enterprises, and small to medium sized businesses are all ideal environments for DENT deployment. Wiring closets in many facilities are small. Staff expertise may be limited and branch changes of major vendors may require costly contracts. DENT is easily deployed on white box hardware in small spaces. It can be configured to support dozens of wireless access points and IoT sensors, creating a manageable network to track inventory, monitor on-shelf real estate, analyze customer activity, and make automated payments .

Major members of DENT include Amazon, Delta Electronics Inc, Edgecore Networks, and Marvell. DENT would also like to acknowledge the important contributions of NVIDIA, Keysight Technologies and Sartura.
