Network Control Program
(NCP): A program that controls
the operation of a
communications controller.
Network File Transfer (NFT):
A user-level protocol that enables
the transfer or copying of files
from one node to another or
within asingle node,interactively
or programmatically.
Network Services Procedure
Error (NSPE): An SNA request
from the SSCP to the LU
indicating an error during session
startup or shutdown.
NFT: See Network File
Transfer.
NMS: See Node Management
Services.
node: A set of hardware devices
and associated software at the
end of a data link. In an SNA
network, a node can be either
distributed or host processors,
communications controllers,
cluster controllers, or terminals.
Node Management Services
(NMS): A major software
component of the HP 3000
operating system that provides a
common set of services to HP
networking products. It includes
utilities and commands for
configuration, event logging,
message tracing, link
management, and subsystem
initiation, termination and
control.
node name: A name assigned to
a node configured into a Local
Area Network (LAN). It must be a
maximum of eight characters in
length and cannot be qualified.
NSPE: See Network Services
Procedure Error.
P
Pass Thru: SNA IMF’s
interactive interface, which
allows a terminal or printer to
exchange data interactively with
an IBM host.
Physical Unit (PU): A component
of an SNA node. A PU controls
the resources of a node and
reports errors and physical
failures to the SSCP. One PU
exists per node. A PU is the
access method in a host node, the
NCP in the communications
controller node,and the hardware
and software in the peripheral
nodes.
PU: See Physical Unit.
R
Request Header (RH): Control
information that precedes a
request/response unit (RU). It
specifies the type of RU and
contains control information for
the RU.
