Term:
Internetwork Packet Exchange (IPX)
Definition:
A protocol that allows the exchange of message packets on
an internetwork. The protocol in Novell NetWare that
governs addressing and routing of packets within and
between LANs. IPX packets can be encapsulated in Ethernet
packets or Token Ring frames. IPX operates at ISO/OSI
levels 3 and 4 but does not perform all the functions at
those levels. In particular, IPX does not guarantee that a
message will be complete (no lost packets); SPX has that
job. See also Ethernet, packet, Token Ring network. Compare
SPX (definition 1).
