ICMP
•
3865 GESA-F (T523572): a single-port fiber version compliant with the 1000
Base-SX standard (802.z).
ICMP. See Internet control message protocol (ICMP).
IEEE. See Institute of Electrical and Electronics Engineers (IEEE).
IEEE 802.3. A local area network protocol suite commonly known as Ethernet. Ethernet has
either a 10Mbps or 100Mbps throughput and uses Carrier Sense Multiple Access bus
with Collision Detection (CSMA/CD. This method allows users to share the network
cable. However, only one station can use the cable at a time. A variety of physical
medium dependent protocols are supported.
IEN. See Internet Engineering Note (IEN).
IGP. See Interior Gateway Protocol (IGP).
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.
Interior Gateway Protocol (IGP). The generic term applied to any protocol used to
propagate network reachability and routing information within an autonomous system.
Although no standard Internet IGP exists, RIP is among the most popular.
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 an abstraction of physical hardware
addresses, just as the Internet is an abstraction of physical networks. As assigned to
the interconnection of a host to a physical network, an Internet address consists of a
network portion and a host portion.
Internet control message protocol (ICMP). A maintenance protocol in the Transmission
Control Protocol/Internet Protocol (TCP/IP) suite that is required in every TCP/IP
implementation. The ICMP allows two nodes on an IP network to share IP status and
error information. The ICMP is used by the ping utility to determine the readability of a
remote system.
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.
IP. See Internet Protocol.
