IPX (Internetwork Packet Exchange)

IPX (Internetwork Packet Exchange) is a networking protocol from Novell that interconnects networks that use Novell's NetWare clients and servers.Ê IPX is a datagram or packet protocol. IPX works at the network layer of communication protocols and is connectionless (that is, it doesn't require that a connection be maintained during an exchange of packets as, for example, a regular voice phone call does). Ê

Packet acknowledgment is managed by another Novell protocol, the Sequenced Packet Exchangeª (SPX). Other related Novell NetWare protocols are: the Routing Information Protocol (RIP), the Service Advertising Protocol (SAP), and the NetWare Link Services Protocol (NLSP).ÊÊ Ê

SPX (Sequenced Packet Exchange)

ÊThe NetWare communications protocol used to control the transport of messages across a network. SPX ensures that an entire message arrives intact and uses NetWare's IPX protocol as its delivery mechanism. Application programs use SPX to provide client/server and peer-to-peer interaction between network nodes. SPX provides services at layer 4 of the OSI model.
