What is Xerox Network Systems?
Xerox Network Systems (XNS) is a series of protocols used by Xerox Systems for data communication. Xerox used XNS for file transfers, network resource sharing, packet transfers, routing information forwarding, and remote procedure calls. The basic working mechanism is almost the same as in the TCP / IP protocol, but XNS only contains two network layers. This differs from the seven-tier Open Systems Interconnection (OSI) model, although the functionality is essentially the same.
XNS was a public domain technology, so it became one of the most widely used networking technologies in the 1980s. It has been replaced by the Internet Protocol Suite.
The XNS protocol suite became very popular immediately after its launch in the early 1980s and was used by many local area networks, especially large companies. Over time, changes were made to the log structure to produce more efficient output.
XNS contains two main layers, a network layer and a transport layer. The network layer provides the packet-carrying service and the logical addressing. XNS is designed for many purposes, such as: B. for office applications, transmissions, Communication media and processors. In the XNS suite there is an echo protocol that acts as a door knocker and checks the connection between the two systems. This is similar to pinging in IP systems.
