SPX, and SAP protocols
Application Programmatic Interfaces (APIs)
Supported NetWare Protocols
NonStop IPX/SPX supports the following NetWare protocols: IPX, SPX, SPXII, RIP,
SAP, and NCP (for a brief description of the protocols, see Supported NetWare
Protocols on page 1-1). Figure 2-1 shows the Novell NetWare protocol suite in relation
to the OSI service layers. In the figure, protocols that are open to application
development are unshaded.
The following subsections describe the protocols supported by the NonStop IPX/SPX
subsystem.
IPX
IPX is a connectionless, datagram-oriented, internetworking protocol, where data can
be transmitted with no established connection. The IPX protocol sends outgoing data
packets onto the network and directs incoming data to the proper area within the
workstation’s operating system or the Network Operating System (NOS). Higher-level
