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.

Futuriom: Linux Foundation Unveils DENT 2.0

By Community News

The Linux Foundation has released the second version of its Dent open-source network operating system (NOS), adding improvements specifically aimed at small and mid-size enterprises (SMEs) as well as future applications.

Dent 2.0, code-named Beeblebrox, adds IPv6 scalability along with Network Address Translation (NAT). Also added is Power over Ethernet (PoE), which reduces cabling requirements and allows for remote switches to be monitored and shut down from one interface. Rounding out the improvements is rate limiting, which protects the network against storms of broadcast traffic such as those caused by distributed denial of service (DDoS) attacks. It all adds up to scalability with a focus on simplicity at the edge.

“This new release of Dent 2.0 adds critical updates focused on smaller enterprise needs. This was the goal of Dent all along,” said Steven Noble, Dent Technical Steering Committee Chair, in a prepared statement. “If you are looking for an open source disaggregated network OS, now is great timing for looking at Dent.”

Linux Foundation blog: DENT 2.0, Secure and Scalable Open Source Network Operating System Aimed at Small and Mid-Size Enterprises, Released

By Community News

The DENT project is an open source network operating system utilizing the Linux Kernel, Switchdev, and other Linux based projects, hosted under the Linux Foundation. The project has announced DENT 2.0 is available for immediate download

The “Beeblebrox” release adds key features utilized by distributed enterprises in retail and remote facilities, providing a secure and scalable Linux-based Network Operating System (NOS) for disaggregated switches adaptable to edge deployment. This means DENT provides a smaller, more lightweight NOS for use at the small, remote edges of enterprise networks.

DENT 2.0 adds secure scaling with Internet Protocol version 6 (IPv6) and Network Address Translation (NAT) to support a broader community of enterprise customers. It also adds Power over Ethernet (PoE) control to allow remote switching, monitoring, and shutting down. Connectivity of IoT, Point of Sale (POS), and other devices is highly valuable to retail storefronts, early adopters of DENT. DENT 2.0 also adds traffic policing, helping mitigate attack situations that overload the CPU. 

“DENT has made great strides this past year and with its edge and native Linux approach, with a rich feature set for distributed enterprises like retail or remote facilities. DENT continues to expand into new use cases and welcomes community input with an open technical community, under the Linux Foundation,” said Arpit Joshipura, GM of Networking & Edge at The Linux Foundation.
