He added that in this kind of environment there is an explosion of the number of devices being connected to the network necessitating a different approach to switch management and operation. He described a large retail environment in which thousands of cameras and tens of thousands of labels and sensors are used to keep inventory and process transactions. Remote campus and retail stores are two of the use cases targeted by the project.ĭENT is aimed at solving the next generation of challenges faced by distributed enterprises, like retail businesses, de Lanerolle explained. However, The Linux Foundation argues that many of these projects have failed to meet the needs of distributed enterprise edge and campus environments. The telecom, cloud, and enterprise data center markets have steadily adopted open source NOS like Microsoft’s SONiC and AT&T’s DANOs platforms. It should be noted that desegregated switching is nothing new. This enables developers to treat networking ASICs and other silicon - common in switch appliances - like any other hardware, eliminating a potential pain point. The initial code release is based on the latest Linux kernel, version 5.6, and takes advantage of SwitchDev and other Linux utilities to simplify integrations and abstract away the hardware from the software layer. The release is the culmination of a year’s worth of work that brought together silicon vendors, original design manufacturers, system integrators, and original equipment manufacturers to develop the edge-focused NOS. “DENT is everyman’s, every operator’s sort of NOS.” “Arthur Dent is kind of that everyman character in ‘Hitchhiker’s Guide,’ and we’ve really taken that to heart,” said Trishan de Lanerolle, technical program manager and architect at The Linux Foundation. The first release of network operating system (NOS) is called Arthur, named of course after the protagonist of Douglas Adam’s seminal novel “The Hitchhiker’s Guide to the Galaxy,” Arthur Dent. The Linux Foundation’s disaggregated enterprise edge and campus switching platform, DENT, is now available.
