A network operating system (NOS) is a specialized operating system for a network device such as a router, switch or firewall.. Historically operating systems with networking capabilities were described as network operating systems, because they allowed personal computers (PCs) to participate in computer networks and shared file and printer access within a local area network (LAN).
Network operating systems (NOSs) are operating systems that provide support for computer networking in addition to traditional hardware support. These were an important sub-class of conventional operating systems from the 1980s into the 1990s during the introduction of the early local area network (LAN) systems. As personal computers grew in ...
JNode (Java New Operating System Design Effort), written 99% in Java (native compiled), provides own JVM and JIT compiler. Based on GNU Classpath. [36] [37] JX Java operating system that focuses on a flexible and robust operating system architecture developed as an open source system by the University of Erlangen. KERNAL (default OS on ...
A kernel is the core part of the operating system that defines an application programming interface for applications programs (including some system software) and an interface to device drivers. Device drivers and firmware , including computer BIOS or UEFI , provide basic functionality to operate and control the hardware connected to or built ...
The operating system provides an interface between an application program and the computer hardware, so that an application program can interact with the hardware only by obeying rules and procedures programmed into the operating system. The operating system is also a set of services which simplify development and execution of application programs.
The free community Vyatta Core software (VC) was an open source network operating system providing advanced IPv4 and IPv6 routing, stateful firewalling, secure communication through both an IPSec based VPN as well as through the SSL based OpenVPN. [10] In October 2013, an independent group started a fork of Vyatta Core under the name VyOS. [11]

The software decouples network software from the underlying hardware and is built on the Switch Abstraction Interface API. [1] It runs on network switches and ASICs from multiple vendors. [2] Notable supported network features include Border Gateway Protocol (BGP), remote direct memory access (RDMA), QoS, and various other Ethernet/IP ...
