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.
