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). |
