IPX/SPX was the de facto standard for DOS-era multi-user network games. This greatly simplified maintenance of client workstations on the network. Later implementations allowed the network stack to be loaded and unloaded dynamically, using pre-existing modules.

This executable would be loaded at boot time, and remain resident in memory until the system was shut down. Initial versions required a hard-linked protocol stack, where a separate executable would be created by the network administrator for each network card configuration on the network. Novell's original NetWare client was written for DOS.
#Novell netware disadvantages software
Novell was largely responsible for the use of IPX as a popular computer networking protocol due to their dominance in the network operating system software market (with Novell Netware) from the late 1980s through the mid-1990s. NetWare communication requires an NCP implementation, which can use IPX/SPX, TCP/IP, or both, as a transport. This is in part due to its superior performance over wide area networks and the Internet (which uses TCP/IP exclusively), and also because TCP/IP is a more mature protocol, designed specifically with this purpose in mind.Äespite the protocols' association with NetWare, they are neither required for NetWare communication (as of NetWare 5.x), nor exclusively used on NetWare networks. TCP/IP has, however, become the de facto standard protocol.

IPX/SPX was primarily designed for local area networks (LANs), and is a very efficient protocol for this purpose (typically SPX's performance exceeds that of TCP on a small LAN, as in place of congestion windows and confirmatory acknowledgements, SPX uses simple NAKs). IPX and SPX both provide connection services similar to TCP/IP, with the IPX protocol having similarities to IP, and SPX having similarities to TCP. SPX is used primarily by client–server applications. The SPX layer sits on top of the IPX layer and provides connection-oriented services between two nodes on the network. IPX is a network layer protocol (layer 3 of the OSI Model), while SPX is a transport layer protocol (layer 4 of the OSI Model). IPX and SPX are derived from Xerox Network Systems' IDP and SPP protocols, respectively.
