|(networking, protocol)||Sequenced Packet Exchange - (SPX) A transport layer protocol
built on top of IPX. SPX is used in Novell NetWare
systems for communications in client/server application programs, e.g. BTRIEVE (ISAM manager).|
SPX is not used for connections to the file server itself; this uses NCP. It has been extended as SPX-II. SPX/IPX perform equivalent functions to TCP/IP.
