Example types with xns
The same corpus examples are grouped by length and sentence type, making it easier to see the contexts in which the word appears:
AppleTalk used XNS-like routing, but had incompatible addresses using shorter numbers. (12 words)
Nevertheless, many portions of the AppleTalk system have direct analogs in XNS. (12 words)
The protocol suite specifications for XNS were placed in the public domain in 1977. (14 words)
XNS was widely regarded as faster than IP due to this design note.sfn In keeping with the low-latency LAN connections it runs on, XNS uses a short packet size, which improves performance in the case of low error rates and short turnaround times. (45 words)
This led to complete fragmentation of the XNS market, and has been cited as one of the reasons that IP easily displaced it.sfn Authentication The XNS protocols also included an Authentication Protocol and an Authentication Service to support it. (40 words)
Individual XNS host pairs on a particular network might use larger packets, but no XNS router is required to handle them, and no mechanism is defined to discover if the intervening routers support larger packets. (35 words)

AppleTalk used XNS-like routing, but had incompatible addresses using shorter numbers.
A wide variety of proprietary networking systems were directly based on XNS or offered minor variations on the theme.
Because Courier was used by all applications, the XNS application protocol documents specified only courier function-call interfaces, and module+function binding tuples.
Error correction could be optionally added at higher levels in the protocol stack, for instance, in XNS's own SPP protocol.
Further development followed, resulting in the seminal Xerox Network Systems (XNS) protocol, which was completed by 1978.
Nevertheless, many portions of the AppleTalk system have direct analogs in XNS.
Some of the protocols in the XNS suite were lightly modified versions of the ones in the Pup suite.
The primary part of XNS is its definition of the Internal Transport layer (layer 1), which corresponds to OSI's Network layer, and it is here that the primary internetworking protocol, IDP, is defined.
The protocol suite specifications for XNS were placed in the public domain in 1977.
This helped XNS become the canonical local area networking protocol, copied to various degrees by practically all networking systems in use into the 1990s.
This reflects the fact that LANs generally have low-error rates, so XNS removed error correction from the lower-level protocols in order to improve performance.
XNS added the concept of a network number, allowing larger networks to be constructed from multiple smaller ones, with routers controlling the flow of information between the networks.
XNS combined the OSI's Session and Transport layers into the single Interprocess Communications layer (layer 2).
XNS, like Pup, also uses EP, the Error Protocol, as a reporting system for problems such as dropped packets.
XNS predated and influenced the development of the Open Systems Interconnection (OSI) networking model, and was very influential in local area networking designs during the 1980s.
XNS was used unchanged by 3Com 's 3+Share and Ungermann-Bass 's Net/One.
