4 unusual facts about IPX/SPX


Windows Open Services Architecture

These extensions include, among others, ODBC (called the "crowning jewel of WOSA"), TAPI, WOSA/XFS, SAPI and MAPI, and their supporting services, as well as the abstraction of access to printers, modems, and networking services, which run identically over TCP/IP, IPX/SPX, and NetBEUI.

Winsock

Included in the Windows Sockets API version 2.0 are functions to use IPX/SPX, although the protocol was all but obsolete already at the time WSA 2.0 shipped.

It also formalized support for multiple protocols, including IPX/SPX and DECnet.

Xerox Network Systems

Sequenced Packet Protocol (SPP) was an acknowledged transport protocol, analogous to TCP; one chief technical difference is that the sequence numbers count the packets, and not the bytes as in TCP and PUP's BSP; it was the direct antecedent to Novell's IPX/SPX.


Babylon 5: The Shadow Within

The novel details how Anna became involved with the IPX expedition to Z'ha'dum, how she met Morden and how she became the Shadow-infested shell of who she had once been who returned to the station in the final episode of season three of Babylon 5.

Local area network

Although this market segment is now much reduced, the technologies developed in this area continue to be influential on the Internet and in both Linux and Apple Mac OS X networking—and the TCP/IP protocol has now almost completely replaced IPX, AppleTalk, NBF, and other protocols used by the early PC LANs.

OSI model

Roughly speaking, tunneling protocols operate at the transport layer, such as carrying non-IP protocols such as IBM's SNA or Novell's IPX over an IP network, or end-to-end encryption with IPsec.

Small Press Expo

Since 1997, SPX has been held in conjunction with the International Comics and Animation Festival (ICAF) many times.
