G
gateway A node that connects two
dissimilar network architectures. A
gateway can be either a single node (full
gateway) or two gateway halves.
gateway half A node that works in
conjunction with another node on another
network to form an internetwork. The only
protocol used by gateway halves is the NS
Point-to-Point 3000/iX Link. See also full
gateway.
gateway-half link A link between the two
nodes of a gateway-half pair. Each of the
two nodes of a gateway-half pair has a
configured link (hardware interface card)
that is used for the gateway half network
interface. The NS Point-to-Point 3000/iX
Link is the only link that can be used as a
gateway-half link.
gateway-half pair A set of two nodes that
are joined by a gateway-half link. Each
node in the pair must have a gateway-half
network interface configured, using the
link.
guided configuration A method of
configuring a node in which a subset of the
complete NMMGR interface is presented,
and defaults of configurable values are
used automatically.
H
handshaking A communications protocol
between devices or between a device and
the CPU. Provides a method of determining
that each end of a communications link is
ready to transmit or receive data, and that
transmission has occurred without error.
hop count See internet hop count and
intranet hop count
host-based network management A
method of managing asynchronous
communications for HP e3000 computers.
All of the control software is configured on
a single host and is downloaded to the
DTCs that are managed by that host. With
host-based management, a permanent
relationship exists between each DTC and
the host. Terminal users can access only
the single system that owns the DTC their
terminal is connected to.
host-based X.25 The management of X.25
network connections from a host computer.
Host-based X.25 network connections are
made through a DTC Network Access card
installed in a DTC managed by the host.
All configuration is accomplished using the
NMMGR utility. It is not necessary for a PC
to be part of the LAN when you are using
host-based X.25.
host computer Theprimaryorcontrolling
computer on a network. The computer on
which the network control softwareresides.
For HP purposes, it can also be used to
distinguish the HP e3000 system (host)
from the DTC.
HP block mode A block mode
transmission method employed by HP
computers where the system controls the
block mode handshake. When HP block
mode is used, the user program need not
concern itself with data transfer protocol.
HP PPN Hewlett-Packard Private Packet
Network. Hewlett-Packard’s own packet-
switching X.25 network, which gives users
full control over the administration and
security of their data communication.
HP TS8 A terminal server that can
support up to eight asynchronous serial
connections. When used in back-to-back
configuration, users can access HP e3000
MPE/V systems on it through a DTC.
