network service provider (NSP) process
network service provider (NSP) process. A process in the Open Systems Interconnection
(OSI) subsystem that performs service and protocol functions for the Network Layer
and, for local area networks (LANs), some functions of the Data Link Layer
. NSP
processes are provided by these underlying subsystems: X.25 Access Method (X25AM),
Compaq NonStop TCP/IP, and the Tandem LAN Access Method (TLAM) for D4x-
series releases or the Port Access Method (PAM)
for G06 and later releases.
nonsensitive command. A Distributed Systems Management (DSM)
command that can be
issued by any user or program allowed access to the target subsystem—that is, a
command on which the subsystem imposes no further security restrictions. For Compaq
data communications subsystems, the nonsensitive commands are all those that cannot
change the state or configuration of objects (usually information commands). Compare

NSAP. See network service access point (NSAP)
.
NSAP address. See network service access point (NSAP) address
.
object-name template. In Distributed Systems Management (DSM)
, a name that stands for
more than one object. Such a name includes one or more wildcard characters, such as *
and ?.
Open Systems Interconnection (OSI). A set of standards used for the interconnection of
heterogeneous computer systems, thus providing universal connectivity.
Open Systems Interconnection (OSI) address. The address of an object on the network,
which includes the network service access point (NSAP)
, transport selector (TSEL),
session selector (SSEL), and presentation selector (PSEL). See also Open Systems
Interconnection (OSI).
Open Systems Interconnection (OSI) manager process. A process in the Open Systems
Interconnection (OSI) subsystem that performs subsystem management functions,
including management of the Management Information Base (MIB). There is one OSI
manager process per OSI subsystem. See also Open Systems Interconnection (OSI)
.
Open Systems Interconnection (OSI) Reference Model. A communications architecture,
adopted by the International Standards Organization (ISO) in 1984, that includes seven
layers that define the functions involved in communications between two systems, the
services required to perform these functions, and the protocols associated with these
services. See also Open Systems Interconnection (OSI)
.
Open Systems Interconnection (OSI) subsystem. One Open Systems Interconnection (OSI)
manager process controls one or more TAPS and TSP processes. The OSI manager
processes communicates with NSP processes but do not control them. The OSI manager,
TAPS, TSP, and NSP processes can be on the same or different nodes within the same
Expand network. See also Open Systems Interconnection (OSI)
and Open Systems
Interconnection (OSI) manager process.
