LAT architecture
A layered networking model that identifies LAT communications functions, assigns
specific functions to distinct layers, and specifies general rules for communication
between
LAT nodes
.
LAT Control Program
A control program that provides a command interface that allows system and network
managers to set up and manage an operating system as a
LAT service
.
LAT network
All the computer systems, or nodes, on a
LAN
that support the
LAT protocol
constitute
a LAT network.
LAT node
A computer on a
LAN
that contains LAT software. There are two types of LAT nodes:
nodes that access services and nodes that offer services; some nodes perform both
functions.
LAT protocol
An integral part of the LAT architectural model that consists of rules that specify the
actual format and sequence of the messages used for communication between
LAT
nodes
.
LAT service
A resource on the
LAT network
.
learned data
Data entered into a access server database by
DNS
. Contrast with
local data
.
load host
A computer on the same
LAN
as the access server that is used to downline load the
access server image
to the access server. A load host can also receive upline dumps of
access server memory.
load host database
A database that contains information about access servers and that allows the load host
to perform downline load and upline dump operations. This database contains three
databases on the load host: the
DECnet
operational database, the DECnet permanent
database, and the
access server configuration database
(that is, DSVCONFIG.DAT).
local area network
See
LAN
.
local data
Data entered into a access server database by a user.
Contrast with
learned data
