Internet Protocol, IP datagram, Keepalive timer

Internet Protocol

See TCP/IP.

Internet Protocol. See TCP/IP.

IP datagram

Internet. A basic unit of information transferred over the Internet.

IVP

Installation Verification Procedure. This procedure verifies that the access server software was successfully installed on a OpenVMS load host.

KDC

Key Distribution Center. A Kerberos host that serves to validate a user’s identity with a Kerberos user name and password.

keepalive timer

LAT. Because access servers are responsible for monitoring its balanced virtual circuits, each access server maintains a keepalive timer. This timer determines the length of time that a balanced circuit remains inactive.

Kerberos

An authentication service that enhances security in an open network. It was developed as part of Project Athena at Massachusetts Institute of Technology. Project Athena is a software development project that facilitates communication among file servers and workstations in a distributed network environment.

Key Distribution Center

See KDC.

keyword

A word in a command string that further defines the command.

LAN

local area network. A network in which communications are limited to a moderately sized geographic area such as an office building or a campus.

LAT

local area transport. DIGITAL name for the Ethernet protocol used by the DECserver for terminal connections.
