Xerox Network Systems (XNS)

The network architecture developed by the Xerox Corporation in the 1970s. The XNS Internet protocol suite is similar to the TCP/IP suite. However, different packet formats and terminology are used. XNS protocols establish a means of transport for data across an interconnection of network or Internet. A sample library provides user applications for XNS, such as the courier, associate printing, filing, and clearinghouse protocols.
