Glossary
store and forward to transfer
packets between each network
that it belongs to.
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. Eachof thetwo
nodes of a gateway-half pair hasa
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 Amethod
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 Acommunications
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 3000
Series 900 computers. All of the
controlsoftwareis 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.
