Institute of Electrical and Electronics Engineers
(IEEE)
Institute of Electrical and Electronics Engineers (IEEE). An international industry group
that develops standards for many areas of electrical engineering and computers.
interactive command. In DSM, a command entered by a human operator rather than by a
program. See also programmatic command.
interface. A node's attachment to a link. This is equivalent to a subnet object within the
TCP/IPv6 subsystem and a LIF in the SLSA subsystem.
interface identifier. A link-dependent identifier for an interface that is (at least) unique for
each link. Stateless address autoconfiguration combines an interface identifier with a
prefix to form an address. From address autoconfiguration's perspective, an interface
identifier is a bit string of known length.
International Organization for Standardization (ISO). A United Nations organization,
established to promote the development of standards to facilitate the international
exchange of goods and services and to develop mutual cooperation in areas of
intellectual, scientific, technological, and economic activity.
International Telecommunications Union Telecommunications (ITU-T). An international
body of member countries whose task is to define recommendations and standards
relating to the international telecommunications industry. The fundamental standards
for ATM have been defined and published by the ITU-T (previously CCITT).
Internet. Physically, a collection of packet switching networks interconnected by gateways,
along with protocols that allow them to function logically as a single, large, virtual
network. When written in uppercase, INTERNET refers specifically to the DARPA
Internet and the TCP/IP protocols it uses.
Internet address. The 32-bit address assigned to hosts that want to participate in the
Internet using TCP/IP. Internet addresses are the abstraction of physical hardware
addresses, just as the Internet is an abstraction of physical networks. Actually
assigned to the interconnection of a host to a physical network, an Internet address
consists of a network portion and a host portion. The partition makes routing efficient.
Internet Control Message Protocol (ICMP). An integral part of the Internet Protocol (IP)
that handles error and control messages. Specifically, gateways and hosts use ICMP
to send reports of problems about datagrams back to the original source that sent the
datagram. ICMP also includes an echo request/reply used to test whether a destination
is reachable and responding.
Internet Engineering Note (IEN). A series of notes developed in parallel to RFCs and
available across the Internet from the INIC. IENs contain many of the early theories on
the Internet.
Internet Protocol. The Internet standard protocol that defines the Internet datagram as the
unit of information passed across the Internet, and that provides the basis for the
Internet, connectionless, best-effort, packet-delivery service.
