The DentProject has released a new network operating system called DentOS 3.0 which is based on the Linux kernel and is designed to equip switches, routers, and other specialized network equipment. Originally founded by Amazon to equip network equipment in its infrastructure, the project was later transferred to the protection of the Linux Foundation and key participants that include Delta Electronics, Marvell, NVIDIA, EDGECORE NETWORKS, and WISTRON NEWEB (WNC). The DENTOS code is written in SI language and is distributed under the free license eclipse public license.
The system environment is based on the distribution of Open Network Linux (ONL), which uses the DEBIAN GNU/Linux package base to provide an installer, settings, and drivers for launching on switches. ONL is developed by the Open Compute project and represents a platform for creating specialized network devices that supports the installation of more than a hundred different models of switches. The composition includes drivers for interacting with indicators used in switches, temperature sensors, coolers, tires i2c, GPIO, and sFP transverse.
To control DentOS, users can use the IPROUTE2 and IFUPDown2 tools, as well as GNMI (GRPC Network Management Interface). For configuration, DentOS uses Yang data models (Yet Another Next Generation, RFC-6020). The linux kernel SwitchDEV is involved in DentOS to control the switching of packages, allowing you to create drivers for discompens Ethernet, capable of delegating personnel redirecting and processing network packages with specialized hardware chips.
The software stack is based on the default Linux network stack, the NetLink subsystem, and tools such as IPRoute2, tc (Traffic Control), brctl (Bridge Control) and FRRouting. It also includes VRRP (Virtual Router Redundancy Protocol), LLDP (Link Layer Discovery Protocol), and MSTP (Multiple Spanning Tree Protocol) protocols.
DentOS is available for switches based on Asic Marvell and Mellanox, numbering up to 48 10 gigabit ports. It works with various ASIC and networking chips, including Mellanox Spectrum ASIC-Chips, Marvell Aldrin 2, and Marvelllls AC3X.
The release of DentOS 3.0 gives users a reliable and high-performance platform for their specialized networking needs.
