HP NonStop TCP/IP, Parallel Library TCP/IP,
and NonStop TCP/IPv6
NonStop TCP/IP, Parallel Library TCP/IP, and NonStop TCP/IPv6 provide TCP/IP
connections for the NonStop S-series server. The TCP/IP products connect the
NonStop S-series server to a variety of UNIX systems, including the Integrity series
(the HP fault-tolerant UNIX systems), Sun and HP workstations, Windows-based
personal computers (PCs), and various large systems such as those manufactured by
HP under the DEC name, Cray, Unisys, and IBM. The TCP/IP products also support
the UDP protocol. The Parallel Library TCP/IP and NonStop TCP/IPv6 products
support Ethernet connections and X.25 through the WAN subsystem; only NonStop
TCP/IP supports token-ring and ATM connections.
Figure 10-1 on page 10-4 shows the relationship of the TCP/IP products to other HP
products that you use to achieve a connection. Notice that TCP/IP on the NonStop
S-series server relies on the ServerNet LAN systems access (SLSA) subsystem for
connection to a local area network (LAN), the X25AM subsystem for connection to a
wide area network (WAN) (NonStop TCP/IP only), and the ATM subsystem for
connection to an ATM network (NonStop TCP/IP only).
For WAN connections, as shown in Figure 10-1, the connection passes to the packet
switching data network (PSDN) and for ATM connections, the connection passes to an
ATM LAN or WAN network.
Note. Parallel Library TCP/IP and NonStop TCP/IPv6 do not support subnets of type X25 but
X.25 functionality is supported on these products through the X25AM and WAN subsystems.
See the X25AM Configuration and Management Manual for more information.
