Novell IPX
Although newer implementations of Novell operating systems use TCP/IP, the Novell IPX
protocols are still required knowledge for the written test. This section discusses the IPX
protocols.
IPX Protocols
Figure 12-8 shows the NetWare protocol suite and the relationship with the OSI reference
model from the network layer and up. IPX runs over the commonly implemented Layer-2
protocols, such as Ethernet, Token Ring, PPP, and so on.

IPX
IPX is the network layer protocol that legacy Novell systems use (especially in version 3.x).
IPX is a connectionless packet-based protocol, which is similar to IP. IPX uses IPX Routing
Information Protocol (RIP) or
NetWare Link Services Protocol
(NLSP) for routing.
SPX (Sequenced Packet Exchange)
SPX
protocol is the NetWare connection-oriented transport protocol. SPX is a reliable,
connection-oriented protocol that supplements the datagram service provided by the IPX,
NetWare's network layer (Layer 3) protocol.
NetWare Core Protocol (NCP)
NCP is a series of server routines designed to satisfy application requests coming from, for
example, the NetWare shell. The services provided by NCP include file access, printer access,
name management, accounting, security, and file synchronization.
