Glossary
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. Eachofthe two
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.
hardware handshake Uses
modem signals CTS and RTS to
pace the data transfer from the
DTC to the attached device. (For
DTC 72MX only.)
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 MPE/iX 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 MPE/iX system that
owns the DTC their terminal is
connected to.
host computer The primary or
controlling computer on a
network. The computer on which
the network control software
resides. For HP purposes, it can
also be used to distinguish the
MPE/iX system (host) from the
DTC.
HP ARPA Telnet Express A
DTC dedicated to providing
protocol conversion between
Telnet on TCP/IP and AFCP to
allow incoming calls from the
ARPA environment to HP 3000
systems.
