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.
