Sequenced Packet Exchange         
<networking, protocol> (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. http://developer.novell.com/research/appnotes/1995/december/03/04.htm. [Better reference?] (1999-05-27)
Sequenced Packet Exchange         
Sequenced Packet Exchange (SPX) is a protocol in the IPX/SPX protocol stack that corresponds to a connection-oriented transport layer protocol in the OSI model. Being reliable and connection-oriented, it is analogous to the Transmission Control Protocol (TCP) of TCP/IP, but it is a datagram protocol, rather than a stream protocol.
