Qué (quién) es Internetwork Packet eXchange - definición

PROTOCOL MAINLY USED FOR NOVELL COMPUTER NETWORKING

IPX

Internetwork Packet eXchange

<networking> (IPX) A network layer protocol initially developed at XEROX Corporation and made popular by {Novell, Inc.} as the basic protocol in its Novell NetWare {file server} operating system. A router with IPX routing can interconnect {Local Area Networks} so that Netware clients and servers can communicate. The SPX transport layer protocol runs on top of IPX. (1997-03-04)

Sequenced Packet Exchange

PROTOCOL USED BY NOVELL COMPUTER NETWORKS

Sequenced Packet exchange; 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

PROTOCOL USED BY NOVELL COMPUTER NETWORKS

Sequenced Packet exchange; 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.

Internetwork Packet Exchange

Internetwork Packet Exchange (IPX) is the network layer protocol in the IPX/SPX protocol suite. IPX is derived from Xerox Network Systems' IDP. It also has the ability to act as a transport layer protocol.

The IPX/SPX protocol suite was very popular through the late 1980s and mid-1990s because it was used by Novell NetWare, a network operating system. Due to Novell NetWare's popularity, IPX became a prominent protocol for internetworking.

A big advantage of IPX was a small memory footprint of the IPX driver, which was vital for DOS and Windows up to Windows 95 due to the limited size at that time of conventional memory. Another IPX advantage is easy configuration of its client computers. However, IPX does not scale well for large networks such as the Internet. As such, IPX usage decreased as the boom of the Internet made TCP/IP nearly universal.

Computers and networks can run multiple network protocols, so almost all IPX sites also run TCP/IP, to allow Internet connectivity. It is also possible to run later Novell products without IPX, with the beginning of full support for both IPX and TCP/IP by NetWare version 5 in late 1998.
