Techopedia Explains Sequenced Packet Exchange

SPX is primarily used for client/server applications to provide connection-oriented network services similar to TCP/IP. SPX sits above IPX, which is a network layer protocol.

IPX/SPX is derived from Internet Datagram Protocol (IDP) and Sequenced Packet Protocol (SPP), which are Xerox Network Systems protocols that provide routing capability and sequenced and connectionless packet delivery support.
