network subscribed facilities A set of
parameters that the user chooses when he
subscribes to the X.25 network; they include flow
control negotiation, use of D-bit, throughput class
negotiation and extended packet sequence
numbering.
network transport Software that corresponds to
layers 4 and 3 of the OSI network architecture
model. The function of this software is to send data
out over the appropriate communications link, to
receive incoming data, and to route incoming or
outgoing data to the appropriate destination node.
NFT Network File Transfer. The network service
that transfers disk files between nodes on a network.
NI See network interface.
NMCBACK.PUB.SYS The default file name for the
file that contains a copy of the information contained
in the configuration file (NMCONFIG.PUB.SYS). The
backup file is updated each time the configuration
file is successfully validated.
NMCONFIG.PUB.SYS A file that contains all the
network configuration data for the HP 3000 Series
900 computer on which it resides. It includes
information about the DTCs that can access the
system as well as information about any Network
Services (NS) products running on the system. This
is the only file name allowed.
NMDUMP Node management services trace/log file
analyzer. A utility used to format log and trace files.
NMMAINT Node management services
maintenance utility. A utility that lists the software
module version numbers for all HP AdvanceNet
products, including NS 3000/iX. It detects missing or
invalid software modules.
NMMGR Node management services configuration
manager. A software subsystem that enables you to
configure DTC connectivity and network access
parameters for a HP 3000 Series 900 computer.
NMMGRVER Node management services
conversion utility. A conversion program that
converts configuration files created with NMMGR
from an earlier version to the latest format.
NMSAMP1.PUB.SYS Sample configuration file
supplied with FOS that can be used as a template
for DTS configuration.
node A computer that is part of a network. The DTC
is also considered to be a node and has its own
address.
node address The node portion of an IP address,
which consists of a node portion and a network
portion.
Node Management Services Configuration
Manager See NMMGR.
node name A character string that uniquely
identifies each system in a network or internetwork.
Each node name in a network or internetwork must
be unique; however, a single node can be identified
by more than one node name.
node names list List defined on the OpenView
workstation and subsequently downloaded to all
DTCs for which it is the “owner.” The list specifies all
the HP 3000 Series 900 hosts on the LAN that are
accessible from the DTCs.
non-adjacent Describes a node on an NS
Point-to-Point 3000/iX network that is separated
from a given node by intervening or intermediate
node.
non-nailed device A session accepting device that
is not permanently associated with an ldev number
at configuration time. When the user at such a
device logs on to a HP 3000 Series 900, an ldev is
assigned from a pool of ldevs set aside for this
purpose at configuration time. The association
between a non-nailed device and this temporarily
assigned ldev exists only for the duration of the
session. One advantage of the use of non-nailed
device connections is that configuration is simplified,
since it is not required that each non-nailed device
be individually configured.
NS 3000/iX A Hewlett-Packard data communication
product that provides minicomputers. NS 3000/iX
consists of one or more links and network services.
NS 3000/iX Link Software and hardware that
provides the connection between nodes on a
network. Some of the N S3000/iX links available are
the ThinLAN 3000/iX Link and its ThickLAN option,
