I
idle device timeout A timeout defined by
the Configure: CPU command. When the
timer lapses,a device connected to the DTC
user interface that is still inactive will be
disconnected.
IEEE 802.3 A standard for a broadcast
local area network published by the
Institute for Electrical and Electronics
Engineers (IEEE). This standard is used
for both the ThinLAN and ThickLAN
implementations of the LAN.
IEEE 802.3 multicast address A
hexadecimal number that identifies a set of
nodes. This address is used for multicast
delivery.
IEEE 802.3 nodal address A unique
hexadecimal number that identifies a node
on an IEEE 802.3 LAN.
IEEE 802.5 A standard for a Token Ring
network published by the Institute for
Electrical and Electronics Engineers
(IEEE). This standard is used for the Token
Ring 3000/iX Network Link.
initialization string A sequence of
control characters used to initialize a
terminal, printer, or plotter when a
connection is established from a host on the
network.
interactive communications Processing
that allows users to enter commands and
data at the terminal and receive an
immediate response. Interactive processing
occurs in session mode on MPE/iX systems.
internet communication
Communication that occurs between
networks.
internet hop count The number of full
gateways plus the number of gateway-half
links that a packet must pass through in
moving from source node to destination.
internet protocol A protocol used to
provide routing between different local
networks in an internetwork, as well as
among nodes in the same local network.
The Internet Protocol corresponds to
Layer 3, the Network Layer, of the OSI
model. See also IP address.
internet routing Internet routing
involves all the processes required to route
a packet from a node on one network to a
destination node on another network.
internetwork Two or more networks
joined by gateways.
intranet communication
Communication that occurs between nodes
in a single network.
intranet hop count The number of
intermediate nodes that lie between a
source and destination node on the same
point-to-point network.
intranet routing Intranet routing
involves all the processes required to route
a packet from one node in a network to
another node in the same network.
intrinsic A system routine accessible by
user programs. It provides an interface to
operating system resources and functions.
Intrinsics perform common tasks such as
file access and device control.
IP See internet protocol.
IP address Internet Protocol address. An
address used by the Internet Protocol to
perform internet routing. A complete IP
address consists of a network portion and a
node portion. The network portion of the IP
address identifies a network, and the node
portion identifies a node within the
network.
