SPX: Sequenced Packet Exchange

The Sequenced Packet Exchange (SPX) protocol is Novell’s legacy transport layer protocol providing a packet delivery service for Novell NetWare network. SPX is based on the Xerox Sequenced Packet Protocol (SPP). SPX operates on top of IPX and is used in Novell NetWare (prior to NetWare 5.0) systems for communications in client/server application programs, e.g. BTRIEVE (ISAM manager). SPX performs equivalent functions to TCP. The newer versions of NetWare services are run on top of TCP/IP.
