About NetWare Networking Protocols
The IPX protocol provides both IPX services and RIP services. As LAN
drivers deliver packets to IPX, the IPX driver uses RIP to determine the
route for packets outbound to other networks. Packets addressed to a local
host are routed by IPX to the applications.
When setting up NetWare from the HP-UX server console, you will need to
configure your IPX internal LAN address and maximum hops, plus other
information. See “Managing NetWare Protocols” and “Managing the
Server” later in this chapter or the Command Reference for more
information.
IPX Addressing IPX delivers packets using a 12-byte network address,
which consists of three address components:
• Network address (4 bytes). Identifies a specific logical network or LAN on an
IPX internetwork; all NetWare servers, routers and clients cabled to this segment
with a common frame type must use the same network address.
• Node address (6 bytes). Identifies the individual nodes on the network. The
factory-defined IX number on the NIC usually defines node addresses for client
workstations. Server machines can have a logical node address.
• Socket address (2 bytes). Identifies processes or functions within a node. The
destination for a packet is the socket address.
The following example illustrates an IPX address (it is usually represented
in hex bytes). The address 01010393.0123456789ab.0451 represents the net,
node, and socket as in the following:
Sequenced Packet eXchange (SPXII)
The SPXII is a connection-oriented, reliable, sequenced transport protocol.
This protocol provides message-level service (for reliability) rather than
packet-level service.
SPXII also provides flow control which regulates the speed with which
packets are sent and received by both sending and receiving processes.
