6 ROUTING WITH IPX

	This chapter provides an overview of IPX routing, including:
■ What part IPX plays in the NetWare environment
■	How IPX works
■ What elements are necessary for IPX routers to transmit packets effectively
IPX Routing in	The NetWare® network operating system was developed and introduced to
the NetWare®	the market by Novell, Inc. in the early 1980s. Much of the NetWare
Environment	networking technology was derived from Xerox Network System (XNS)TM, a
	networking system developed by Xerox Corporation.

The NetWare operating system is based on a client/server architecture where clients request certain services from servers such as file access and printer access. As a network operating system environment, the NetWare operating system specifies the upper five layers of the OSI reference model. It provides file and printer sharing and supports various applications such as electronic mail and database access.

Figure 6-1 illustrates a simplified view of NetWare’s better-known protocols and their relationship to the OSI reference model.
