Network operating system

Source: Wikipedia, the free encyclopedia.

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

network stack
to support a client–server model.

History

Early microcomputer operating systems such as

hard disk.[1] As local area network technology became available, two general approaches to handle sharing of resources on networks arose.[citation needed
]

Historically a network operating system was an

Novell NetWare using the Internetwork Packet Exchange (IPX) network protocol and Banyan VINES which used a variant of the Xerox Network Systems (XNS) protocols.[citation needed
]

These limited client/server networks were gradually replaced by

Windows for Workgroups (adding NetBIOS to Windows). Examples of early operating systems with peer-to-peer networking capabilities built-in include MacOS (using AppleTalk and LocalTalk), and the Berkeley Software Distribution.[citation needed
]

Today,

groupware applications have become the norm. Computer operating systems include a networking stack as a matter of course.[1] During the 1980s the need to integrate dissimilar computers with network capabilities grew and the number of networked devices grew rapidly. Partly because it allowed for multi-vendor interoperability, and could route packets globally rather than being restricted to a single building, the Internet protocol suite became almost universally adopted in network architectures. Thereafter, computer operating systems and the firmware of network devices tended to support Internet protocols.[5]

Network device operating systems

Network operating systems can be embedded in a router or hardware firewall that operates the functions in the network layer (layer 3).[6] Notable network operating systems include:

Proprietary network operating systems

FreeBSD, NetBSD, OpenBSD, and Linux-based operating systems
